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.
