The SN008G listing ("Model: SN008-G") sells the 40mm SN008 with a PT5000 at $326 or a Sellita SW200 at $456; this file is the PT5000 version, sn008-sw200 the SW200 one, and sn008-nh35 the NH35 SN008-G-B. Brand specs: 316L, 40mm, 48mm lug-to-lug, about 11.5mm including the domed sapphire crystal with AR coating (side not stated), 20mm lugs, ceramic bezel (direction, clicks and lume not stated), matte black, blue, brown or green dial with metal markers (a grey dial is also sold, with logo only), GS-style second hand, "retro luminous effect" on the black dial and BGW-9 on the blue (other dials not stated), screw-down crown with hexagon logo, screw-in solid caseback, solid steel bracelet with a "solid turtle back buckle" (clasp type and micro-adjust not stated), 200m, about 140g total. The NH35 SN008-G-B is quoted at 48mm lug-to-lug like this one but 11.95mm thick. Every dial is offered with or without the San Martin logo at the same price. The brand's own image names call it a "BB58 Vintage Diver", kept as inspired_by; photos show no date window, so complications are time only. Every variation showed "Out of stock" on 2026-10-24, so production status is unknown.
