A naval-inspired tool watch built for exploration.
The HMAF Supermarine 40 Date reflects Bremont’s Royal Navy heritage through robust engineering, water resistance and purposeful design.
We carry it for its ultra-matt 904L steel case, ceramic bezel and limited-edition military provenance.
For clients who value performance with a connection to service and adventure, it is Bremont’s modern dive watch with enduring character.
A robust automatic calibre built for life beneath the surface.
The BB64AH powers the HMAF Supermarine 40 Date with a 56-hour power reserve and a 28,800 vibrations-per-hour frequency. Designed for Bremont’s Supermarine collection, it combines reliable performance with protection against the demands of professional tool-watch use.
Servicing is handled through Bremont’s authorised service network, with specialist care to maintain the calibre’s long-term performance.
The watch, by the number.

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.
