San Martin SN0036-GC: what the model offers

The SN0036-GC is a 41mm automatic dive watch built around the , sapphire crystal and a 316L stainless-steel case. The listing specifies 600m water resistance, a screw-down crown and a helium escape valve. Those are finished-watch specifications; the movement itself does not determine the water-resistance rating.

How large does the SN0036 wear?

The case is listed at 41mm, while the bezel is 40mm. For wrist fit, also compare the 48.5mm lug-to-lug length and 13.4mm thickness. The watch is listed at about 179g, so it is substantially heavier than a titanium diver of similar diameter.

Bezel, crystal and lume

The product uses sapphire crystal with AR coating and a 120-click unidirectional bezel with ceramic insert options. The 12 o'clock bezel marker is luminous. The dial and hands use BGW-X1 blue and C3 green lume according to the current listing.

Bracelet and OTF clasp

The stainless-steel bracelet tapers from 20mm to 18mm and uses an On The Fly adjustable clasp. The OTF mechanism lets you make small fit changes without removing bracelet links, which is useful as wrist size changes during the day.

Who is this watch for?

The SN0036-GC is a fit for buyers looking for a full-size steel automatic diver with sapphire crystal, a ceramic bezel, high stated water resistance and an adjustable bracelet. If lower weight or smaller dimensions matter more, compare other models in our collection or the broader collection.
