The GS case family — find your size
| Case | Diameter | Lug-to-Lug | Character |
|---|---|---|---|
| GS Watch Case 39mm v2 | 39mm | 46mm | Faceted dress case, largest |
| GS Watch Case 36mm v2 | 36mm | 43mm | Faceted dress case, classic mid-size |
| GS Diver 36mm · YOU'RE VIEWING THIS | 36mm | 43mm | Dive-styled GS, 200m bezel look |
All three are the same GS platform — 316L steel, 200m / 20 ATM, a double-domed sapphire pre-installed, 28.5mm dials, an SKX013 chapter ring, and a 20mm bracelet or strap. The 39 and the Diver are NH34 GMT-ready; the 36mm dress runs NH35/36/38 plus Swiss ETA and Sellita.
Heads up — what's in the box, and what's sold separately.
This case ships with the sapphire crystal pre-installed. The dial, hands, chapter ring and movement are chosen separately — build it to fit our full dial range .
Chapter ring. This case needs an SKX013 chapter ring to seat the dial correctly — it is mandatory and never included. It takes both normal and ultra thin chapter rings; the choice depends on your dial, not the case. If your dial has applied (raised) indices, pick an ultra thin chapter ring for clearance; a flat-printed dial works with either. Browse SKX013 chapter rings .
Crown. Screw-down, SKX-style — chosen separately. Browse SKX013 crowns .

The case ships with the sapphire crystal pressed in. You choose the rest below — every part is an Add dropdown on this page — and the caseback you select sets which movement family the case fits.
Five more parts make a complete watch, each a dropdown above, in the order you'd assemble them:
Building an NH34 GMT? Add a GMT 24H hand and a GMT / NH34-specific dial — the 24-hour hand is the one optional extra.
Optional extras (also dropdowns above): a 20mm bracelet or leather strap , and a Côtes de Genève decorated bridge + rotor — only visible through a sapphire caseback, and our bridges pair only with our rotors, so pick them together.
Want it built for you?
Under ADD, tick Assemble Watch (+SGD $100) and we'll do the full build in our Singapore workshop — movement seating, caseback fit, crown alignment, dial and hands, and a final function check.
Heads up: assembled watches need 2–5 business days of workshop time before they ship.
