Pressure is the defining force of a dive watch. Every meter below the surface increases the load on the crystal, the case, and crown. As the water presses inward, every component answers in kind, maintaining the integrity of the watch while the automatic movement continues its steady rhythm inside. A mechanical movement gives a watch life. Pressure reveals its character. The GSAR was engineered to meet that challenge, dive after dive, long after the surface is out of sight. #purposebuilt
