About this entry
74% of key specs known. Missing: hardening, bracelet links, end links, link attachment, clasp micro-adjust.
The first SN0005 GMT listing (the brand writes both SN005 and SN0005). Kept apart from the later 40mm Hangzhou 6460 version (sn0005-hangzhou-6460) because the brand gives different case dimensions: 40.5mm without crown, 48mm lug-to-lug and about 13.5mm including crystal, against 40mm, 48.5mm and 13mm for the SN005-G2-GMT and SN005-GMT-4; the listing adds that its figures are hand-measured and may contain errors, so this may be the same case. Brand specs: 316L, 20mm lugs, domed sapphire with Swiss AR coating (side not stated), curved sapphire bezel insert with lume, matte black or white enamel dial, GS-style hands, retro yellow-green lume (no grade given), screw-in crown with shark logo, screw-in solid caseback, 200m, about 140g (not stated what was weighed). The bracelet is described as a "solid five-ball steel bracelet", but the listing photos show a three-piece oyster-style link, so style and link count are left blank; the clasp is only called "solid clasp". Bezel direction and click count are not stated. Black or white dial with or without logo, all $399. Every variation showed "Out of stock" on 2026-10-24, so production status is unknown. Inspired_by is read from the design (red and blue 24-hour bezel); the brand does not name it.
