Dependable Divers with shock resistance of 7,500 Gs.
The "Safety Lock Crown System" protects the crown, the weak point of mechanical watches, and has passed a shock test equivalent to the shock a watch would receive if it fell from a height of approximately 1.5 meters to a wooden floor due to a free fall. Furthermore, the movement is equipped with a chronometer movement that has been inspected and passed by the C.O.S.C., an official Swiss institution.
