Blancpain aims to raise €250,000 for ocean conversation with limited edition Flyback Chronograph


Blancpain has created a limited edition Ocean Commitment II Flyback Chronograph that will raise money to support scientific marine expeditions.

The Fifty Fathoms Bathyscaphe Flyback Chronograph Blancpain Ocean Commitment II (BOC II) comes for the first time in an all-blue ceramic case.

Only 250 numbered pieces have been released and, for every one sold, Blancpain will donate €1000 to support scientific expeditions until its €250,000 target is reached.


Blancpain has been funding research and protecting ocean expeditions since 2014 under its Blancpain Ocean Commitment project, which has so far paid for ten expeditions and secured three million square kilometers of ocean.


The new Flyback Chronograph BOC II is equipped with an F385 caliber whose mechanism beats at 36,000 vibrations an hour (5 Hz).

The F385 has a variable-inertia balance with gold screws for 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. In addition, like all recent movements made by the Manufacture Blancpain, this caliber is equipped with a silicon balance-spring.

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.

Blancpain has not revealed a price for the limited edition piece, but its Flyback Chronograph BOC II typically sells for around £9000.
