A choice we can defend in person.
Bremont has made British tool watches since Nick and Giles English founded it in Henley-on-Thames in 2002, with genuine aviation and maritime lineage and a refusal to pretend a watch is more than its job. We carry the house because that honesty holds even when the materials turn dressier.
The Supermarine 300m Date Bi-Colour proves the point, pairing 904L steel with 18ct rose gold across the bezel and crown while keeping the 300m rating and unidirectional dive bezel intact. A brown gradient dial carries marine-instrument crosshairs, and the case back is engraved with the world's oceans. It suits someone who wants a true diver's tool with a warmer, more formal finish.
Hand-finished, made to be serviced.
The Modified Calibre 11 1/2”’ BE-92AV carries 25 Jewels jewels, 50-hour of power reserve, beating at 28,800bph (4Hz).
Servicing is organised through us and the manufacture, and the watch comes back to your wrist — with a loaner in the meantime.

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, handle the shipping both ways, and put a loaner on your wrist while you wait.
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.
When your watch is at service we will put another independent on your wrist, so the wrist is never empty.
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.
