Designed to push the limits, the compressor case stands out thanks to its dual crowns. The first allows the internal bezel to be adjusted, thus avoiding any risk of inadvertent manipulation. It is not screwed onto the case to allow its adjustment underwater, while maintaining the water resistance of 200m (20 ATM). The second crown at 4 o'clock is used to wind the automatic movement and to set the time. An engraved grid finish completes the aesthetic of the two crowns.
