A watch that refuses to look like anything else.
The Darkmoon is unmistakably U-BOAT: bold, technical and designed with a presence conventional sports watches rarely attempt. Its signature Oil Immersion system creates striking depth beneath the domed sapphire crystal.
A black PVD-treated steel case and black dial provide the stealth-like foundation, while yellow Super-LumiNova across the numerals, indexes and hands delivers an unmistakable flash of colour.
We carry it for clients who want something different — a watch with attitude, technical character and a distinctly Italian point of view.
Swiss quartz precision, immersed in oil.
The Ronda 762 quartz movement brings reliable Swiss precision to the Darkmoon, with its distinctive construction lubricated by an oil bath. This signature U-BOAT approach supports smooth operation while contributing to the watch’s characteristic sense of depth and technical identity.
Quartz means straightforward ownership: accurate, dependable and designed for minimal intervention. When service is required, we coordinate it through U-BOAT’s authorised service network.

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 U-Boat 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.
