A study in proportion and restraint.
The NOMOS Glashütte Tetra 27 Duo Doré Ref. 405 brings a refined simplicity to the distinctive square Tetra form, with compact 27 mm proportions and subtle gold accents. Its two-hand display removes everything non-essential, allowing the geometric case and clean dial to take centre stage, while the hand-wound DUW 4001 Duo calibre delivers precise Glashütte craftsmanship.
We carry it for collectors who appreciate considered design — where distinctive geometry, mechanical simplicity and independent watchmaking come together.
A refined calibre built for essential timekeeping.
The DUW 4001 Duo is an in-house, manually wound manufacture movement that pares timekeeping back to its essentials while retaining the hallmarks of Glashütte watchmaking. Its three-quarter plate, Glashütte stopwork, tempered blue screws and fine ribbing and perlage are complemented by the NOMOS Swing System and DUW regulation system. Regulated in six positions with a 53-hour power reserve, it combines mechanical simplicity with meticulous finishing.

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 NOMOS Glashütte 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.
