Bremont has announced an update to their GMT Supermarine collection, the S302 in multiple colors including a green/blue design that shows off the watch’s GMT movement.

From the release:

A distinctive bi-colour blue and green aluminium unidirectional rotating bezel is introduced for the first time with the two tones giving the indication of day and night and new numerals. The S302 Jet edition boasts a black DLC case complemented by a black ceramic unidirectional rotating bezel and a sandblasted black dial, a classic Bremont ‘Jet’ design. Both models are punctuated with accents of vibrant orange, from the outline of the GMT hand, across key markers on the inner bezel through to the ‘Supermarine’ wordmark on the dial. With visibility being of paramount importance, Super-LumiNova® has been applied across both models with blue emission indexes and hands. A contrasting green emission lume has been applied to the GMT hand.

Caller GMT

The watch is a caller GMT which means the GMT hand moves instead of the hour hand. This is because the watch uses a modified ETA 2893-A2 aka their own BE-93-2AV.

The grey Ocean model is special in that its a partnership with “Ocean Ramsey and her partner Juan Oliphant. Based in Hawaii, Ocean is a marine biologist, shark and marine conservationist, professional freediver and scuba instructor, author, and model whilst Juan is a marine conservationist, award-winning photographer and videographer.”

The Ocean is limited to 400 pieces.

“Juan and I are honored to be working with Bremont on the release of this special timepiece and to be raising funds for a cause we care so deeply about,” Ocean said. “We look forward to showing you the watch in action through the content we’ll be sharing, and we hope to inspire and educate others about the incredible marine environment we’re lucky to experience on such a regular basis.”


The watches cost a heady $4,000 but it’s a pretty handsome bit of kit so it might be worth it.
