Its Crown Protection System™ helps to guarantee its water-resistance.
Its bracelet can only be closed if the crown at 6 o’clock is perfectly screwed down.
Its ECS™ system ensures optimal rinsing after a dive and eliminates impurities and salt crystals lodged between the unidirectional rotating bezel featuring a ceramic insert and the case.
