About this entry

79% of key specs known. Missing: hardening, end links, link attachment, clasp micro-adjust.

The SN036 is a 20mm-lug steel diver sold as the SN036-G (41.5mm, 200m, Miyota 8215 or 8315), the SN036-G-B (helium valve, 300m, NH35, sn036-nh35) and the SN0036-C (helium valve, 600m, Seagull ST2130, sn036-st2130). The SN036-G listing sells the same watch with a Miyota 8215 at $258 or a Miyota 8315 at $278; this file is the 8315 version and sn036-8215 the 8215 one. Brand specs: 316L, 41.5mm, 48.5mm lug-to-lug, 13.7mm (not stated whether including crystal), 20mm lugs, sapphire with AR coating (side not stated), enamel blue, black or green dial, broad arrow luminous hands, BGW-9 blue lume on hands and markers, screw-down crown with hexagon logo, screw-down caseback with a deep-pressed 3D shark, solid 316L bracelet, folding clasp with safety, 200m, about 168g (read as on the bracelet, the only option offered). The listing doesn't describe the bezel: photos show a 60-minute dive bezel in the dial colour; its direction and insert material are not stated. Bracelet style and link count are from photos. Each dial is sold with or without the logo at the same price. The movement has a date but photos show no date window, so complications are time only. Every variation showed "Out of stock" on 2026-10-25, so production status is unknown.
