Description
With its navy blue/black gradient dial, satin-finished steel case and metal bracelet, this version represents the quintessence of the Grands Fonds 300® diver’s watch. 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. Its hands are orchestrated by a reliable Swiss Made self-winding calibre.
