The Supermarine Descent is named as a tribute to the original Limited Edition Bremont Supermarine Descent, Bremont's first limited edition dive watch. The watch is powered by the self-winding chronometer-tested BE-93-2AV movement, with the patented anti-shock case mount. The Descent II can withstand depths of up to 500M. The 43mm titanium case, with bronze bezel, has a black dial that features the hours, minutes, seconds, date and GMT. It also has an automatic helium escape value for professional diving requirements.
