About this entry

93% of key specs known. Missing: hardening.

Combines the SN029-G listing (written "SN0029-G" in its spec list) and its SN029-G-V2 version, which quote the same 38mm (without crown), 47.5mm lug-to-lug, 11.5mm (including crystal) case with 20mm lugs and show the same sandblasted case. The V2 names an Epson YN55A; the SN029-G says "we have just few with Time Module NH35 movement, most will be with YN55 movement", so YN55A is recorded and a few early SN029-G watches may have an NH35. Brand specs: 316L (V2: sand-blasted), sapphire with AR coating (side not stated), lumed hands (V2: sword hands), vintage-tone lume (SN029-G: yellow-green; V2: Super-LumiNova C3), screw-down crown (7mm, "S" logo on the V2), screw-down caseback, 20mm straight nylon strap with a stainless steel pin buckle (no bracelet offered), 200m, about 89g for the V2 (not stated what was weighed). SN029-G dials are listed as black, retro yellow and retro gray; the photos show black dials with gilt print and cream lume (likely the retro yellow) but the retro gray isn't clearly shown, so its colour is left blank. SN029-G dials come with a text or hexagon logo, the V2 with or without logo, all at $158. Photos show no date window, so complications are time only. Both listings showed "Out of stock" on 2026-10-24, so production status is unknown. The 41mm SN029-G2 is a different case (sn029-8215, sn029-8315).
