79% of key specs known. Missing: hardening, bracelet links, end links, clasp micro-adjust.
The 38mm SN0004 case with an Epson YN55A instead of the NH35. The SN004-G-V2 listing says the whole V2 ("new model with YN55A movement") has it: a brown leather-texture dial (S logo on the crown) and a black dial with 3/6/9 numerals (hexagon logo on the crown), both with gilt Mercedes hands. The SN004-G-V3 listing sells its leather dial with the YN55A (DLC gold pencil hands) and its black dial with an NH35; the black one is in sn0004. Each dial comes with or without logo at the same price. Brand specs (both listings): 316L, 38mm, 46mm lug-to-lug, 13mm including crystal, 20mm lugs, sapphire "imitating bubble mirror effect" with Swiss AR coating (side not stated), screw-down crown, screw-down solid caseback, retro yellow-green lume (no grade given), solid steel bracelet with screws and female end links, "solid steel clasp" (type and micro-adjust not stated), 200m, about 140g (not stated what was weighed). The bezel is not described on these listings; photos show the same black 60-minute insert as the other SN0004s. The YN55A has a date but the dials have no date window, so complications are set to time only. Both listings showed "Out of stock" on 2026-10-24, so production status is unknown. The brand's "6200" naming of the SN0004 is kept as inspired_by.
