About this entry

79% of key specs known. Missing: hardening, end links, link attachment, clasp micro-adjust.

The 40mm SN0005 GMT with a Hangzhou 6460 (the brand writes both SN005 and SN0005). Two listings with identical case specs: SN005-G2-GMT ($368, "Vintage" full-lume SLN C3 green) and SN005-GMT-4 ($378, BGW9 blue lume), each in matte black or enamel white with or without logo at the same price. Brand specs: 316L, 40mm, 48.5mm lug-to-lug, 13mm thick (not stated whether including crystal), 20mm lugs, domed ("bubble") sapphire with AR coating (side not stated), bidirectional 24-click bezel with red and blue sapphire insert and full lume, four-hand GMT, screw-down crown with 3D hexagon logo, circular satin-brushed screw-down caseback (solid or display not stated), 316L 5-link bracelet (jubilee style in the photos), folding clasp with safety (no micro-adjust mentioned), 200m, about 143g (not stated what was weighed). The G2 listing also gives the movement's 25 jewels and 28,800 vph. Inspired_by is read from the design (red and blue 24-hour bezel, jubilee bracelet); the brand does not name it. The NH34 versions of this case (SN005-B1/B2/B3, 48.7mm lug-to-lug) are in sn0005-nh34, and the earlier 40.5mm SN005-G is in sn0005-40-5mm-hangzhou-6460. Both listings showed "Out of stock" on 2026-10-24, so production status is unknown.
