8999€ for this scarce yema jumbo Yachtingraf régate " Blue-ship " Patent Pendind : The rarest version of the Yema Yachtingraf (already very rare and sought-after) in exceptional condition. Year +/- 1969 (she's 55 years old!) Very few examples on the market. The ultimate evolution of the 1967 Yema Yatchingraf cruiser, adopted by the greatest sailors (Éric Tabarly...) A large-size model with its mythical "blue-ship" logo at 6 o'clock, surmounted by the no less famous "patent pending" mention. A breathtakingly charming and technically sophisticated dial in unique condition! Specialists best describe the charm of its specific operation: "On the special totalizer on the right-hand side, this countdown timer, which operates over a ten-minute period, animates the apertures in the upper part of the totalizer as soon as the chronograph starts. These apertures report and break down the 5 minutes preceding the start, while the blue and red zones on the lower graduations are a precious visual aid for the skipper, enabling him to estimate the time remaining before he can cross the starting line. Modified Valjoux 7733 movement with 30-second increments: "a device that ensures the utmost precision in the final minutes of the countdown. To achieve this, the wheel that drives the large central seconds hand has a double "finger", so it remains to follow the progress of the disc, which turns red in the upper part, in order to release the ship's power and start the race at the sound of the cannon that marks the starting signal" This watch, a true icon of navigation, remains one of the most emblematic models of racing and water sports".
