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.
