Why we carry it

A dive watch defined by colour and capability.

The Sommerso Ceramic Green brings U-BOAT’s bold Italian design language to a modern dive watch, pairing a deep green ceramic identity with the brand’s unmistakable oversized proportions.

We like the balance between technical purpose and visual character. Its 300-metre water resistance, ceramic construction and vulcanised rubber strap make it ready for adventure, while the green and black palette sets it apart.

We carry it for clients who want a sports watch with personality—functional, distinctive and far from conventional.

For the life of the watch

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.

i.
Service, organised through us

When the time comes, we arrange the full service through U-Boat and handle the shipping both ways.

ii.
Straps & bracelets, for life

Replacement straps and bracelets at cost, in any material the manufacture offers, fitted in person at the bench.

iii.
One person, not a call centre

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.
