A refined dive watch with serious engineering underneath.
The Supermarine 300m brings Bremont’s professional dive-watch expertise into a slimmer 40mm 904L steel format, built around durability, comfort and legibility.
We carry it for its naval-inspired design, gradient green dial and versatile construction suited for both exploration and everyday wear.
For clients who value performance with refined sports-watch character, it is Bremont’s modern approach to underwater adventure.
A proven automatic calibre, refined for Bremont performance.
The Modified Calibre 11 1/2’’’ BE-92AO powers the Supermarine 500m with Bremont’s performance enhancements, delivering reliable precision and a 42-hour power reserve. Modified and tested to Bremont’s standards, it is built to withstand the demands of a professional dive watch.
Servicing is handled through Bremont’s authorised service network, with specialist care to maintain the calibre’s long-term reliability.

A relationship, not a transaction.
Every watch we sell stays close to us. We organise servicing, source straps, and answer the telephone ourselves — for as long as the watch is yours, and the wrist after that.
When the time comes, we arrange the full service through Bremont and handle the shipping both ways.
Replacement straps and bracelets at cost, in any material the manufacture offers, fitted in person at the bench.
You speak to Jason — for a warranty question, a service interval, or simply a second opinion — for as long as you own the watch.
Hold it once. Turn it over.
A watch makes more sense in the hand than on a screen — particularly through the sapphire back. Book a viewing at 900 West Hastings St., Vancouver and we will put a loupe in your hand.
