About this entry
74% of key specs known. Missing: hardening, bracelet links, end links, link attachment, clasp micro-adjust.
Two listings sell the same YN55 diver case: the SN088-G ($249; black or blue with or without logo, green with logo) with enamel dials and polished hands, and the later SN088-G2 ($248; black, blue or green, with logo) with wave-pattern dials and sword hands. Both are recorded as the YN55A, as on the published SN0004, SN006 and SN074. The SN088-G quotes a 41.5mm case with a 42mm bezel, 49.6mm lug-to-lug and 13mm; the SN088-G2 quotes 42mm, 49mm and 13.5mm. San Martin hand-measures and the photos show the same case, bezel and bracelet, so the two are recorded as one model with the larger figures (neither says whether the thickness includes the crystal). Shared brand specs: 316L, 20mm lugs ("lug to lug width"), sapphire with AR coating (side not stated), 120-click ceramic bezel with lumed 12 o'clock marker (direction not stated), BGW-9 blue lume on hands and markers, screw-down crown with hexagon logo, screw caseback, solid 316L bracelet with a folding clasp with safety (micro-adjust not stated), 200m. Weight is the SN088-G2's "about 165g" (not stated what was weighed; the SN088-G leaves it blank). Photos of both show no date window, so complications are time only. Inspired_by is read from the design (Seamaster-style bezel with 15/45 numerals, wave dials and sword hands on the G2); the brand does not name it. Every variation of both listings showed "Out of stock" on 2026-10-25, so production status is unknown.
