Stealthy & refreshed for a new era of exploration

The Bremont Supermarine S302 "JET" with its stealthy black DLC case is a mission-ready mechanical timepiece with GMT function, 50-hour power reserve and 300m water resistance — all features that together yield the ultimate adventure companion, wrapped up in a highly wearable 40mm silhouette. 

The trademark of the Supermarine collection is that it highlights the connection between sea and air, a range that has been designed for the water but very much inspired by aviation principles. Turning the watch over reveals a closed case back with an etching of the Supermarine Seaplane, a nod to the watches’ namesake, the 1930s aircraft company, Supermarine, whose first ever Spitfire prototype (the Type 300) led to one of Britain’s most iconic aircraft.

Newly refreshed for 2023 with a lightly updated dial aesthetic, this reference now incorporates a bi-directional ceramic rotating bezel, with a 60-minute index now dedicated to the inner dial chapter ring. It is manufactured using Bremont’s signature Trip-Tick® three-piece case construction with a black DLC-coated case barrel, which protects a beautifully finished and chronometer-tested movement that beats within.
