yema yachtingraf regate

Regatta Yachttimers

An overview of sailing regatta watches.

The only French brand in this regatta-yachttimer overview is Yema. Founded in 1948 in Besançon (Doubs) by Henry Louis Belmont, the company distinguished itself in the very beginning by creating the first automatic chronometers manufactured entirely in France. The brand became fairly popular in France in the 1960’s and 1970’s with both consumer and military sales, including the watches related to the French space missions!

On March 3, 1967  Henry L. Blum of Montres Yema S.A. filed a patent for a ‘Watch for Yachting and Underwater use’ . You can download the complete Swiss patent (CH 483.047) as a PDF here , or here if you prefer English (USA 3,427,800).

  Yema patent US3,427,800 filed by H.L. Blum.

This resulted in the introduction of the Yema Yachtingraf   in 1966. All together 6 different models (7 if you count type 6 in standard or jumbo case as two) of the Yachtingraf  were sold between 1966 and 1970. Type 1 (Valjoux 92), type 2 ( Valjoux 7733 or 7734) and type 3 (Valjoux 7734 with date) have a subdial counting the seconds at 9 o’clock, and an oversized 30 minutes subdial at 3 o’clock, divided into 6 differently coloured segments representing 5 minutes each.

Yema Yachtingraf, 3 versions, 3 different calibers.

Model: Yema Yachtingraf – type 1.

• Reference: the first model, rare, two subdials at 3 and 9 o’clock.
• Caliber: manual wound Valjoux 92 movement.
• Case size: Ø 38 mm
• Year: 1966.

Model: Yema Yachtingraf – type 2.

• Reference: two subdials at 3 and 9 o’clock.
• Caliber: manual wound Valjoux 7733 / 7734 movement.
• Year: 1966/1967.

Model: Yema Yachtingraf  – type 3.

• Reference: two subdials, and a date window at 6 o’clock.
• Caliber: manual wound Valjoux 7734 movement.

Type 4 and 5, the Yachtingraf Croisière models, have an extra third subdial at 6 o’clock with a 12 hour register. By means of a red cross over this subdial it counts double, up to 24 hours. Type 6 has an indicator disk underneath the dial, for an optimum countdown.

And the Yema Yachtingraf versions 4, 5 and 6.

Model: Yema Yachtingraf Croissière – type 4.

• Reference: 92 001L. Silver subdial at 9 o’clock, third subdial at 6 o’clock,
• Caliber: manual wound Valjoux 72 movement.
• Year: 1969.

Model: Yema Yachtingraf Croissière   – type 5.

• Reference: 9314. Black subdial at 9 o’clock, third subdial at 6 o’clock.
• Caliber: manual wound Valjoux 7736 movement.
• Case size: Ø 38 mm.

Model: Yema Yachtingraf Régate  – type 6.

• Reference: with a special indicator disk in stead of a hand.
• Caliber: manual wound Valjoux 7733S movement.
• Case size: either normal case Ø 39 mm or jumbo size Ø 44 mm.
• Year: 1970.

The Yema Yachtingraf Régate was available in two different case sizes, the first one with the black logo at 6 o’clock measuring Ø 39 mm and with a tachymeter along the outer edge of the dial, and a second version with the blue logo at 6 o’clock measuring Ø 44 mm. The last one is also referred to as Régate – Jumbo.

How the countdown function works:

Definitely type 6 is the most interesting one. It has a 15 minutes register at 3 o’clock, and a smal indicator disk that rotates under a special cut-out in the dial. The indicator disk moves every 30 seconds, jumping half a minute further to the start of the race.

The Yema Yachtingraf Régate has the crown to set the time at 3 o’clock and two pushers for the countdown function. One pusher at 2 o’clock for start/stop, and one pusher at 4 o’clock for reset.

After a reset the countdown subdial shows 1-2-3-4-5 and red in the 6th small window. When the chronograph is activated at the first gunshot the countdown starts and the big white sweep hand is set in motion clockwise. After 30 seconds the indicator disk moves half a minute, and so it does again after 60 seconds, now showing 0-1-2-3-4. A slide bar shows the first minute in blue. After the first 5 minutes of the countdown, when the second gunshot is fired, the 6th window in the dial takes over the countdown: 5 more minutes to go.

Again one minute later, with another 4 more minutes to go, the first window is showing red. Three minutes later, only 1 more minute to go, and 4 windows showing red. Then, as the final gunshot sounds, all 5 windows are red and the 6th window shows 0. Off you go!

Variations:

The Yema Yachtingraf’s are unmistakable recognizable by their big colorful minutes countdown subdial, which is also well described in the patent listed above. And although they are not related to Yema in any way, several smaller watch brands have used the same subdial for a Yachting version of their watch. Probably with a license by Yema for the dial layout. The only exeption is the brand Le Jour, which was actually the North American rebranded distributer for Yema in the 1970’s and 1980’s. Here are some examples:

Branded Alsta Le Jour Yachtingraf , Le Jour Yachtingraf   (US version) and Thermidor De Luxe Yachtingraf :

Branded Puerto Azul (without it’s bezel),  Technos Sportsgraph  (with a Landeron 248 movement) and Relide Spacemaster :

Branded Yachting Chronograph  (Valjoux 7733),  Jaques-Droz and Gallet :

Branded Datzward Seamagnum (Valjoux 7730), Lider Yachtingraf   (Valjoux 7733) and La Martine   (Valjoux 7733):

Branded Lunich Watch (Valjoux 7733), Dichi Watch (Valjoux 7730) and Wingo :

x – x – x – x – x – x – x – x – x – x

In the mid 1970’s the first quartz movements were introduced, and also Yema decided to invest heavily in the research en development of new models with a quartz movement. This resulted among others in the second (quartz) generation of the Yema Yachtingraf   in 1977.

In 1982 John Henry Belmont Jr. takes over as CEO of Yema from his father. But he has other plans with the company, and decided to sell Yema in 1988 to the Japanese Seiko Watch Corporation. In 1995 Yema became a subsidiary to the Hattori-Seiko group under the name Yema S.A. It’s obvious that many of the Seiko movements are used in a Yema watch during that period.

In 1992 Yema is sponsoring the French team with skipper and helmsman Marc Pajot as competitor fort her America’s Cup (with yacht Ville de Paris).  For that occasion Yema launches the  America’s Cup France , with a Seiko 8M35 quartz regatta movement.

Different movement with three pushers, at 2, 4 and 8 o’clock:

And a third movement with two pushers at 8 and 10 o’clock:

From a more recent date are the Yema Yachting   models with an ISA 8270 movement, also quartz:

In 2004 the Yema brand is purchased by its CEO Louis Eric Beckensteiner, with financial help of the French Montres Ambre, a watchmaking and jewelry company. That makes Yema a 100% French watch brand again, with the name being changed into ‘Yema Horlogère Maison Francaise 1948’.

For their 70th anniversary Yema announces in 2018 the Heritage collection, to pay tribute to the brand’s most iconic timepieces: a Superman, a Rallygraf, a Yachtingraf and a Flygraf. The Yema Yachtingraf Heritage is an almost identical copy of the Yachtingraf Crossière (type 5) from 1969. The first 1948 watches will be numbered.

1970s Yema jumbo Yachtingraf Regate “Blue Ship”

The brand Yema, founded in 1948 by Henry Louis Belmont, has a rich history in the realm of French watchmaking. Yema quickly gained recognition for its innovative and affordable timepieces, becoming popular among watch enthusiasts.

In the 1960s and 1970s, Yema made history with iconic models like the Yema Superman, a renowned dive watch celebrated for its durability and advanced features. It was used by professionals and military divers.

Over the decades, Yema continued to expand its range of watches to include models for various activities, from sports to aviation. The brand has also been associated with exceptional achievements, including providing watches for French space expeditions in the 1980s.

From 1969, Yema produced a handful of regatta chronographs featuring a 10 minutes countdown instead of the traditional second chronograph disc. Based on a modified Valjoux 7733, these watches were produced in the strong and distinctive 850737 Yema case, thick, large (42mm) and with beautifully designed crown-guards.

It is commonly admitted that only 25 of them are known, which makes it a very hard catch. And as you will admit that the condition of the example we are offering is simply outstanding, we are not afraid to say that this one is among the best examples out there.

Yema Yachtingraf Regatta Timer 'White Ship'

Why We Love it

We've been fans of Yema for quite some time. While you don't see too many Yachtingrafs on the market in general, this specific variant is as rare as they come.

This particular piece is a Régate, or Regatta Timer, which Yema launched in 1969. Unlike the previous models of Yachtingraf, the Régate featured a modified Valjoux 7733 as its drivetrain, which showed the regatta countdown in numerical format. Moreover, the Régate is the first Yachtingraf to feature crown guards, as well as a ship on the dial, giving rise to the nickname “white ship.”

As rare as it is distinctive, only about 25 of these awesome watches have emerged on the commercial market, so catch this one now before it sails away.

SECOND GENERATION QUARTZ MODELS

In the mid 1970’s the first quartz movements were introduced, and Yema decided to invest heavily in the research and development of new models with a quartz movement. This resulted in the second generation of the Yema Yachtingraf in 1977.

From 1988 until 2004 the Japanese Seiko Watch Corporation was the owner of Yema. The Yema company was then bought back by French investers and renamed as ‘Yema Horlogère Maison Francaise 1948’. For that reason a Seiko movement is used in a Yema watch during 88-94. In 1992 Yema sponsored the French team as competitor at the America’s Cup, with the launch of the Yema Yachtingraf America’s Cup France with a Seiko quartz movement.

Yema Yachtingraf “Regatte”

Description

• Additional Information

This is a rare, late execution Yema “Yachtingraf” Regatte, developed circa 1969-1970. This execution is also nicknamed the “white sail” model, for the placement of a white sail ship at the 6 o’clock marker. This later execution Yachtingraf is the only model to incorporate crownguards on the case.

This Yema Yachtingraf is in great vintage condition. The case does not show signs of overpolishing, and features thick and even lugs. The dial shows only minor blemishing in the 9 o’clock register.

The watch also comes equipped with its original, signed Yema stainless steel bracelet.

YEMA Yachtingraf Croisière

Specially designed for sailing regattas, the YEMA Yachtingraf Croisière is a unique model instantly recognizable by its asymmetrical sub-registers in bright colours inspired by the 1960’s legendary chronograph of the same name. This new, more refined interpretation features an elegant 38.5mm steel case with twisted lyre lugs and is equipped with Seiko’s VK63 tricompax caliber. The Yachtingraf Croisière will be available on yema.com as from July 26 2024 with delivery planned August 10 2024.

Yachting tradition since 1960s

Since the 1960s YEMA has a longstanding tradition in designing purpose-built yachting and regatta chronographs to equip renowned French regatta professionals, as well as regularly acting as official timekeeper of transatlantic solo races like the Route du Rhum.

Historic “Big-Eye” Regatta Chronograph

Vintage-inspired design, the Yachtingraf Croisière has personality thanks to the “big-eye” oversized sub-register. The emphasis of the minutes counter changes the dynamic of the watch greatly, making it stand out from other chronographs. Specially designed for purpose, it acts as a countdown to the start of a sailing race.

A dial that turns heads

The dial is the star of the show mixing bright coulours with YEMA ’s neo-vintage signature quirk. The dial consists of a primary matte surface with raised steel facetted markers in polished finish elegantly matching the polished facetted hour and minute steel hands. The coloured sub-dials is where the magic happens: At nine is the oversized minutes regatta countdown, at six is the sweep seconds hand and at three is the 24h counter in the form of an inverted Swiss-cross.

Thin & Stylish case with lyre lugs

The 38.5mm case in 316L stainless steel is thin (10.30mm) and stylish. In the absence of an external bezel, it offers a large dial opening ensuring perfect readability.The “twisted” lugs, also known as beveled lyre lugs, invented by the famous watch designer Genta, with their polished-brushed finishes ensure a play of different textures which bring relief and personality to this model.

Mechanical-quartz calibre

The time functions of Seiko’s VK63 hybrid movement are powered by a quartz caliber while the chronograph’s function is controlled by a mechanical module which results in a smooth sweeping secondhand movement.

Stylish mesh bracelet

The Yachtingraf’s steel bracelet is made in Milanese mesh for more flexibility and finesse. The clasp is engraved with YEMA ’s historic logo and adjusts quickly and very easily.

• Leather strap

Made by a French manufacture of our region, the grained leather strap with stitches has been specially designed in the Yachtingraf’s matching colours.

YEMA Yachtingraf – THE COMPENDIUM

Yema – a wellknown brand in France, got a eventful history with some take-over. In the 60s Yema produced 300.000 watches per year.

1963 was launched the “Superman”, a 300m water-resistant Watch for professional diver.

1966/67 sold about 400.000 Yema watches. 1968 they constructed the 200m water-resistant Yachtingraf, with Valjoux movement.

The company still exist in other hands till today and produced Yachting watches with Quartz movement in the 80s till now. The Team of the Americas Cup (Marc Pajot, 1991) took the time with Yema watches for example.

But here is the overview of the Yachtingraf watches with real movements.  Feel free to send all comments, facts and things about them if you can add some information please!

There are 7 different main executions of Yachtingraf:

1. 1966 yachtingraf valjoux 92, the first, very rare to find.

Yachtingrafs with differend brand on the dial.

Some dials are known with different brands printed on.

Interesting one found on eBay in Uruguay – Yachtingraf with brand LIDER. Serial doesn´t fit in the line of 2compax Yachtingrafs.

Lider seems to be a brand of Borel Fiels & Cie. SA from Neuchatel, Switzerland or Montres Leader SA. Keep on research.

Yachtingraf with co-branded dials

ALSTA LeJour

The brand seems to owned by Alstater Watch Corp. which was located in N.Y. since 1948. 2-3 are of that co-branded ones seen till now.

LeJour O´day

Justin found this cool 2Compax Yachtingraf with a co-branded dial from O´day Corporation.

O´day was one of the most successful sailboat builders in the US. (source: wikipedia read here )

Luckily Justin found the commercial ad for the cmpaign to “get a free racing watch” with a purchase of a sailing boat.

LeJour KENT Yachting Timer

Just by chance found this LeJour with KENT Yachting Timer on the dial.

credit: unknown. please give us a ping, if you are the owner!

Watches with similar dials but in different cases, not really derivates of the Yachtingraf.

Credits all by Mark or from ebay. Different brands used the dials: Thermidor, Technos, Jaques Droz, Dichiwatch, Sigel and some more.

About the quality and known issues of Yema Yachtingraf watches

Just my point of view, please. Feel free to send my comments if you know something better. Just in case you looking for one to buy these points may help you. The Yema Yachtingraf watches got mostly problems on:

– pushers (not available, normaly screwed in but mostly glued with metall glue) – lumen (uneven made) and many are bad relumed – cases often polished to death – glasses not to find as NOS, no good substitutes – hands are not to find if there are not the original ones – dials could have paintloss or paint bumpinesses (subdials left too!) – bakelitbezels are mostly losses the paint (but that´s not a yema thing alone) – Alubezels are mostly sold as NOS on ebay from France as 70s, they fit perfect and looks good. You can see if it is a “NOS” one on the green triangle at 12, it looks different to the old ones – numbers on the casebacks: different, earlier seems to be upcounting, later ones got mostly the same numbers, unsure about some numbers too (Yema seems to put the numbers on other models too, still to prove) – unbranded bridges / movements – maybe an advantage for doing the service but you will never know if the movement is original built in the watch, only some LeJour got signed bridges

About the different mounted regattahands on the subdial

Wonder why 50% of all bubbles looks to 12 and the other half looks to 6? Simple explaination but very good usability for different types of the regatta countdown (5/10 or 15 min) you find here at the Club Yema , Jerry found out!

About the movements

Just to know: Valjoux 7730 is the 1966 following movement to the Venus 188 (built from 1948-1966) after the take-over of Venus from Valjoux in 1966. The main difference is the cheaper cam-switching instead of high-end column wheel. Yema was one of the first that uses the Valjoux 7730/7734/7736 as substitute for Valjoux 92/72.

Variants: height: 6,00/6,65 mm | diameter 14 line (31mm) | 45 hrs power reserve | 17 rubins | 28.900 A/h (4Hz) – all variants were built over 2Mio. pieces

7730: basic version, built 1966 – 1973, 175k pieces 7731: like 7730 but with new balance piston 7733: redesigned 7731 in 1969 with different reset hammers 7733S: 7733 with regatta-module disc drive 7734: date wheel, not quickset 7736: chronograph with 12 hrs counter (built 1969-1978) 7737: with 10min regatta countdown (for example in Memosail)

Trying to specify the production years with movements for the Yachtingrafs. Help is needed here for the research.

first to last:

1966 – ???? V92 1966/67 – ???? V7730 (following V92) and later 7733 (starting when 1969 with launch of the movement – ????) 1966/67 – ???? V7734 Date 1966/67 – ???? V72 Croisiere 1969 – ???? V7736 (following the V72 Croisiere) 1969/70 – ???? 7733S Regate “white ship” 1970 – ???? 7733S Regate “blue ship”

Next to the Yachting Chronographs there are the well-known Car-Racing Chronographs – the Rallygraf and the Chronograph for the pilots Flygraf (1970).

Le brevet yema yachtingraf….

… ou le mystère d’une aiguille montée à l’envers… par R.C alias Jerry (mise à jour : 3 février 2019)

Qui ne s’est jamais dit, en voyant le compteur ci-contre, « Pfff… Encore une aiguille de Yachtingraf montée à l’envers… » ?

D’autant plus que le catalogue et les publicités de l’époque mettent bien en scène une montre dont l’aiguille est montée dans l’autre sens, non ?

Eh bien selon moi, c’est tout à fait discutable !

D’abord, remontons un peu le cours du temps. En juin 1966 et août 1966 ont été déposés par Henry Louis Blum , et publiés respectivement aux Etats-Unis et en Suisse pour le compte de la marque YEMA, les brevets d’invention horlogère N°3.427.800 et N°483.047 portant sur la création d’un chronographe doté d’une fonction de décompte de départ de régate. Ces deux brevets portent les doux noms de «  Watch for Yachting and underwater use  » pour le brevet américain et  «  Chronoscope » pour le brevet suisse .  Tu noteras la sobriété du second. On est en Suisse. Pas aux «  States « …

Bon. De quoi s’agit-il ?

Petit préambule utile, si tu n’es pas familier des courses nautiques : le départ d’une régate est une phase stratégique de la compétition, qui peut avoir de grosses conséquences sur la suite. Comme les voiliers peuvent difficilement partir à l’arrêt, surtout quand ils sont imposants, il existe un temps préalable au cours duquel les concurrents vont chercher à se placer le mieux possible pour franchir la ligne de départ à pleine vitesse lorsque le top est donné. Evidemment, le concurrent qui franchit la ligne avant le départ est disqualifié, ou doit effectuer une tour de pénalité qui lui fait regretter chèrement son erreur et compromet sérieusement sa course. Le début du décompte et les différentes séquences de cette phase préliminaire sont scandés par des coups de canons et des levées de pavillons. Pour se positionner le mieux possible, et autant que faire se peut, pénaliser leurs adversaires, les concurrents exploitent savamment le sens du vent et les règles de priorité en vigueur. Pour illustrer l’enjeu de cette phase préliminaire, j’ai en tête qu’il est arrivé, au cours de la fameuse compétition de la Coupe America, que les adversaires ne franchissent jamais la ligne de départ, chacun ayant systématiquement réussi à empêcher son rival de se lancer.

Le document du brevet, dans sa version suisse comme américaine, contient un schéma de présentation des différentes fonctions du chrono :

Après le brevet, la montre :

Et là, tu te dis… « Ben ? Elle est dans le même sens que sur le catalogue, là, l’aiguille ?! C’est juste pour me montrer ça qu’il me fait tout un sketch, le gars ? » Ttt Ttt Ttt… Attends !

Le brevet repose sur le postulat qu’il existe dans le monde de la compétition nautique deux zones, au sein desquelles les règles de départ de régate sont différentes. Le compteur du chronographe Yachtingraf est donc coupé en deux, dans la verticale. Petit croquis :

Dans la zone B (Oui, je commence par la Zone « B ». C’est mon droit… non mais sans blague.), on est plutôt cool. On aime bien prendre son temps. Au début je me suis dit « Tiens, ça doit être du côté de la Suisse » (Que les Suisses me pardonnent. C’est grâce à leur calme et patience légendaires qu’ils produisent des montres magnifiques). Ma fille de 4 ans m’a alors fait remarquer sur un ton ironique que la Suisse c’est plutôt montagneux… Je lui ai rappelé l’existence du lac de Genève et je l’ai envoyée au lit. Puis j’ai relu la publicité presse présentée plus haut… et constaté que la Zone « B » se trouve plutôt à gauche de la Bretagne, de l’autre côté de l’Atlantique. Assez loin de la Suisse, finalement. Mais bon… ça, je ne l’ai pas dit à ma fille. J’ai mon orgueil.

Bref. Jon Snow, yachtman émérite qui participe chaque week-end à des compet’ de ouf dans la zone « B » dispose donc de 15mn, divisées en 3 tranches de 5 minutes, pour se taquiner avec ses concurrents et chercher à gagner la meilleure position de départ qui lui permettra, in fine, de monter sur le trône. Euh. Sur la première marche du podium.

Jon Snow utilisera, pour ne pas rater ses départs de régate, la partie gauche du compteur. Le décompte commence en bas du compteur, à 6:00 et remonte par la gauche vers le point « Zéro » du top départ. La partie droite du compteur ne lui sert strictement à rien !

Ragnar Lodbrok navigue, lui, dans une zone du globe où il fait beaucoup plus froid. On n’a pas de temps à perdre avec des ronds dans l’eau diplomatiques. On fait bref et efficace. Donc 10 minutes pour se mesurer à grand coup de « Tribord, nom de Thor ! », c’est largement suffisant. D’autant plus que dans cette zone, plus tu es sorti longtemps de chez toi, plus tu risques de retrouver un autre gars assis à ta place sur le trône, voire dans le lit de ta femme. Tout ça peut se terminer assez vite au grand banquet d’Odin. Chez Ragnar, on aime bien rigoler, mais on n’est pas forcément pressé de trinquer avec les dieux. Donc, dans la zone « A », les départs de régate se font seulement avec un décompte sur 10 minutes, en deux tranches de 5mn, et on rentre vite chez soi avec le butin si on a remporté la coupe en précieux métal. Dans ces conditions, inutile de te préciser, tu l’as déjà deviné, que la partie gauche du compteur de 15mn, Ragnar s’en tamponne très largement la partie inférieure.

Pour terminer la présentation du compteur de décompte, ta sagacité t’aura fait noter que le troisième secteur de la partie droite du cadran n’a absolument… aucune utilité.

Bon. Mais il y a eu dépôt de brevet, quand même ! Il doit bien y avoir une petite particularité horlogère ?! Alors je suis vraiment désolé de te décevoir, mais non. Ce compteur est un tout « bête » compteur de 30mn. C’est d’ailleurs ce qui a permis à la Yachtingraf, sans aucune modification de cadran, d’être animée indifféremment au cours de sa période de production par un Valjoux 92, un Vajoux 7730, un Valjoux 7734 avec date à 6h00, et même un Valjoux 7736 et un Valjoux 72 pour la déclinaison 3 compteurs de la Yachtingraf « Croisière ». De ce point de vue la Yachtingraf « Régate » qui fera son apparition quelques années plus tard, présente un intérêt horloger supérieur. En effet, ce chronographe est équipé d’un Valjoux 7733 modifié : un ergot a été rajouté à la roue du compteur de telle sorte que celui-ci se décale toutes les 30 secondes et non toutes les minutes. Si t’es sage, je te montrerai un jour.

Bon, mais alors ? Tête en haut, ou tête en bas ?

Si l’on retient l’idée que la tête de l’aiguille est la partie portant le cercle évidé, plus facile à identifier d’un coup d’oeil (je te rappelle que Jon Snow et Ragnar Lodbrok doivent simultanément tenir la barre, border leurs écoutes, observer leurs voiles et les concurrents à gauche comme à droite), il est tout à fait cohérent, d’une point de vue fonctionnel, de monter l’aiguille tête en bas ou tête en haut selon que l’on régate respectivement dans zone « B » ou la zone « A » du globe. Les deux sens de montage sont donc parfaitement acceptables, si l’on privilégie la fonction à toute autre considération.

CQFD ! QED ! Ça c’est de la démo !

Euh… Non… C’est pas fini… malgré tous mes efforts de recherche, sur internet, dans les ouvrages spécialisés, comme auprès d’éminents membres et arbitres de la Fédération Française de Voile, je n’ai JAMAIS réussi à mettre la main sur un règle de départ de régate en 15mn… Le texte du dépôt de brevet est assez imprécis : la zone « B » du compteur comprend «  trois tranches de 5 mn de différentes couleurs, représentant les 3 fois cinq minutes accordées généralement au départ des régates dans certains pays « . « Généralement », « certains pays »… Pas bien précis tout ça. Cet usage de zone « B » ne serait-il pas une pure invention marketing ? Il existe pourtant de nombreux autres modèles de chronographes « Yachting » qui présentent le même compteur 15mn, et accréditent donc l’existence de ce type de décompte… sous les marques Heuer (en particulier avec le chrono Heuer Skipper), Jacquet Droz, Technos, Relide… Mais, mais, mais… ils sont contemporains de la Yachtingraf, pour laquelle YEMA a déposé un brevet… Partenariats commerciaux ? Droits d’exploitation de brevet ? Le mystère reste entier.

Quoiqu’il en soit, ce compteur cocardier fait encore courir les amateurs et offre largement de quoi refaire la course au bar !

Concrètement, ça marche comment ?

Rien de mieux qu’une petite mise en situation. L’occasion aussi de découvrir un dernier détail, celui qui m’a le plus amusé dans la compréhension de ce brevet. Pour te présenter tout ça, pas de schéma. Des photos. Comme si tu y étais.

BLAM ! Le premier coup de canon vient d’annoncer le début du temps réglementaire de 10mn (tu ne croyais quand même pas que j’allais te commenter en « direct live « une phase de préliminaire de 15 mn ?! Suis pas assez payé pour ça…)

Ragnar, pensant déjà au doux réconfort de sa magnifique épouse Lagertha lorsqu’il rentrera victorieux, s’est laissé surprendre. Il fait rentrer les avirons, borde sa voile, fait sonner la trompe à la poupe. Ce soir, il doit ramener la coupe à Lagertha ! Sinon, réconfort que dalle ! Il jette un oeil à la Yema Yachtingraf qu’elle lui a offert au solstice dernier. Déjà 1 mn 25 écoulée !

Ragnar aperçoit du coin de l’oeil un concurrent qui le rattrape sur son bâbord arrière. Il vire lof pour lof afin de le contraindre à changer de cap compte tenu du jeu des priorités. Menace momentanément écartée.

BLAM ! Nouveau coup de canon. Tout à sa manoeuvre, Ragnar n’a pas vu le temps passer (‘faut dire aussi qu’un drakkar, ça ne vire pas très vite…). D’où l’intérêt du décompte sonore. Déjà 5 minutes ?!

BLAM ! Coup de canon. dernier décompte de 5mn !

Tu te souviens que Ragnar a été un peu surpris par le premier coup de canon annonçant le début du décompte. Il a donc déclenché son chrono avec quelques secondes de retard. C’est contrariant. Mais Henry-Louis Blum a pensé à tout ! Regarde bien…

Pour Ragnar, le temps s’arrête. Il amène posément le triangle situé à 12:00 de la lunette de son chrono en face de la grande aiguille tachymétrique. Il dispose maintenant, en plus du compteur de décompte, d’une mesure très précise du temps réel restant, essentiel à maîtriser sur la dernière minute précédant le départ.

Bon. Je te rappelle quand même que Ragnar effectue cette manipulation au milieu des embruns, de la houle et des cris… t’imagines ce que ça aurait donné si le temps ne s’était pas suspendu et que l’aiguille avait poursuivi sa course … Si j’ajoute que Ragnar peut avoir dépassé la cinquantaine et qu’il est devenu presbyte… C’est ça, le vrai secret du Brevet Yema Yachtingraf. Il arrête le temps et le mouvement. Mouarf !

BAOOUM ! Plus qu’une minute ! La grande aiguille tachymétrique permet maintenant à Ragnar de suivre avec précision le temps restant avant le coup de canon qui annoncera le départ. Paré à virer ?! Choque tes écoutes ! Vire !

BLAM !  Dernier coup de canon. La course est lancée ! Fonce, Ragnar, Fonce ! Pense à Lagertha !

Accessoirement, si tu regardes la partie gauche du compteur, tu constates que si tu avais été en train de régater à bord du Yacht de  Jon Snow, le coup de canon annonçant le départ de la course pour Ragnar viendrait seulement d’avoir annoncé le début du décompte des 5 dernières minutes avant le départ.

BRAOUM ! Le coup de canon vient de prévenir Jon Snow (celui qui navigue dans la zone « B » et sur le bateau duquel tu n’as pas embarqué étant donné que tu as préféré régater avec Ragnar dans la Zone « A ». Ce serait sympa de suivre quand je t’explique…) qu’il ne reste plus qu’une minute avant le départ (en haut à gauche du compteur). En bas à droite, la tête de l’aiguille parvient à la dernière minute du secteur blanc, « zone morte » inexploitée.

Et voilà. Tu sais tout du brevet Yema Yachtingraf.

En synthèse , si tu t’es endormi au fond de la classe en rêvant de courses de F1.

• Si tu régates avec les règles de course internationales en vigueur, dans la zone que j’ai appelée « zone A », avec une phase préliminaire de 10 mn, tu utiliseras la partie droite du compteur. Le suivi du décompte s’opère en observant la course la tête de l’aiguille (cercle évidé) qui descend vers la droite quand tu lances le chrono. Le « go » du départ est donné lorsque la tête de l’aiguille atteint la limite de la zone rouge, au bout des 10mn.
• Si tu régates avec les règles (introuvables…) de la zone « B », supposée être américaine, avec une phase préliminaire de 15 minutes, tu utiliseras la partie gauche du compteur. Tu suivras cette fois-ci le décompte en observant la course de l’extrémité opposée de l’aiguille (extrémité effilée), qui remonte vers le haut par la gauche du compteur. Le « go du départ sera donné lorsque la pointe effilée atteindra la limite de la zone rouge, en haut à gauche.
• Et si, naviguant dans la zone « B », tu souhaites une meilleure lisibilité, tu optimiseras ton chrono et demanderas à ton horloger de te monter l’aiguille tête en bas, pour que la lecture du temps de décompte soit plus facile !

Il a quand même dû se passer un truc entre ces deux là pendant que MikaWatches et moi-même avions le dos tourné… Tu n’as en effet pas pu manquer la naissance récente de la Yachtingraf Héritage , qui a emprunté à l’une son cadran, et à l’autre son boîtier ! Je dis ça, je dis rien.
