Blancpain: Fifty Fathoms Bathyscaphe Chronographe Flyback14 October 2016
Blancpain introduces the new Fifty Fathoms Bathyscaphe Flyback Chronograph Blancpain Ocean Commitment II. For the first time, this piece features an all- blue ceramic case. For each timepiece sold in this 250-piece limited edition, an amount of 1000 Euro will be donated in support of scientific expeditions. The 250,000 Euro resulting from this will be added to Blancpain’s contributions in support of the oceans.
The new Flyback Chronograph BOC II is equipped with an F385 caliber whose mechanism beats at 36,000 vibrations an hour (5 Hz), an ideal frequency for a chronograph as it enables each second to be divided into intervals of a tenth of a second. The flyback chronograph is driven by a column-wheel. The F385 has a variable-inertia balance with gold screws, ensuring increased robustness and more precise adjustment than the usual index device. This has a vertical clutch that ensures faultless operation of the chronograph and eliminates any unexpected jerking of the watch hand when the chronograph is engaged. Moreover, this solution allows the chronograph mechanism to operate freely without having to worry about any negative effect on the watch’s rate accuracy.
The Flyback Chronograph BOC II incorporates all the technical characteristics of a mechanical diving watch. In particular, it is water-resistant to 300 m and its unidirectional bezel features gray inserts and hour-markers in Liquidmetal®. Aside from this, it has a flyback function that enables immediate resetting of the chronograph to zero or restarting simply by pressing a pusher at 4 o’clock. This 250-piece limited-edition watch is also distinguished by its oscillating weight engraved with the words “Ocean Commitment” linking it to Blancpain’s commitment to the exploration and preservation of the oceans, while the sapphire crystal case-back also reveals the watch’s sporty and sophisticated bridges.
