The Bremont Supermarine S301 Type 300 range was made to be a professional men's diver watch in a slightly smaller version. The watch has a minimalist, vintage appeal. With faux-aged Super LumiNova (as on Bremont’s ALT1-ZT/51 and P-51) and a traditional Sub-like use of dots and hashes for the markers, the S301 is a nod to the early, vintage diving watches of the '50s and ‘60s.
The name ‘Supermarine’ comes from the 1930’s British aircraft manufacturing company, Supermarine. Supermarine’s first Spitfire prototype was named the ‘Type 300’ and it became a very popular aircraft in the country. The S301’s case is narrower and slimmer than its older versions, the S500 and S2000, being only 40mm wide and 13mm thick.
The case is hardened steel combined with Bremont's multi-pieceTrip-Tick design. The Type 300 uses a domed anti-reflective sapphire crystal and a solid steel case back that is printed with a portrait of one of the 30’s Supermarine aircraft designs.The S301’s case is narrower and slimmer than its older versions, the S500 and S2000, being only 40mm wide and 13mm thick.
