The innovative case design consists of a robust carbon-fibre frame that houses the movement and acts as the case middle. This is then sandwiched between a separate case back and front and fixed by sprung titanium screws. To ensure even greater robustness, the rubber strap is integrated into the case itself and fixed by the same screws that hold the sapphire crystal case back in place. The result is a remarkably sturdy timepiece that offers a unique form of shock absorption and guarantees optimum reliability from the movement.
