The Bremont Supermarine Full Ceramic Tactical Black is a high-performance dive watch with 500m water resistance and a helium escape valve. An evolution of our previous Supermarine 500M, the case has been re-designed in mono-block ceramic, a first for Bremont, with a titanium movement container and a new knurled uni-directional titanium bezel. Black and grey woven fabric NATO style strap, meticulously woven on 18th century Jacquard French looms. Self-gripping fastening ensures a secure and comfortable fit.
