About this entry

84% of key specs known. Missing: hardening, end links, link attachment.

Merges the three steel NH35 listings of the SN0111 (G-A, G-B, and G-A3/A4), which quote the same case. Brand specs: 316L, 40mm (the A3/A4 listing gives 39mm for the case, 40mm at the bezel and 41.8mm to the crown guard; the larger figure is recorded), 47.5mm lug-to-lug, 13.2mm (not stated whether it includes the crystal), 20mm lugs (drilled lug holes on the G-A and A3/A4), sapphire with AR coating (side not stated) and no cyclops, unidirectional ceramic bezel with lumed 12 o'clock marker, enamel dial with applied hexagon logo, BGW-9 lume on hands and markers, screw-down crown and brushed screw-down caseback, 300m, about 154g (G-A) or 155g (G-B; not stated what was weighed; the A3/A4 listing gives none). Bracelet: solid 316L, brushed with polished sides, 20mm tapering to 16mm (three-link oyster style in the photos), folding clasp with safety and the "New Fly Adjustable Clasp" (on-the-fly; positions and range not stated). The G-A and G-B dials have no date window, while every A3/A4 variation photo shows a date at 3, so complications are left to the movement. All listings are $238. The 60-minute bezel scale and crown guards are from photos. inspired_by is read from the design (Mercedes or sword hands, ceramic dive bezel, crown guards, oyster bracelet; the G-B's snowflake hands follow the Tudor Submariner); the brand does not name it. Helium valve and hardening are not mentioned for the steel versions. Every variation of all three listings showed "Out of stock" on 2026-10-25, so production status is unknown. The Grade 5 titanium SN0111-T-A1 (PT5000 or SW200) is a separate model (sn0111-titanium-pt5000, sn0111-titanium-sw200).
