About this entry

68% of key specs known. Missing: lug-to-lug, hardening, bracelet links, end links, link attachment, clasp micro-adjust.

The SN086-G listing ("SN086-G MM") sells one NH35A diver with a matte black, blue sunburst enamel or green sunburst enamel dial, each with or without the logo at $268 (a "Custom Logo" option is listed but has no orderable variation). Brand specs: "Time Mudule NH35A", "±15s/day" (recorded as the brand's regulation claim; positions not stated), 316L, 44mm without crown, 13.5mm including crystal, 20mm lugs ("lug to lug width"), sapphire with AR coating (side not stated), applied markers, C3 lume, screw crown, screw-in caseback with shark logo, solid 316L bracelet about 210mm long with a solid steel clasp (type not stated), 300m, about 192g (not stated what was weighed). Lug-to-lug is not stated. Photos show a date at 3 and a 60-minute bezel matching the dial colour; bezel direction and insert are not stated. Inspired_by is read from the design (MM300-style case and bezel, arrow hour hand, large lume plots) and the "MM" in the brand's title; the brand does not name the Seiko. Every variation showed "Out of stock" on 2026-10-25, so production status is unknown.
