About this entry

68% of key specs known. Missing: weight, hardening, AR coating, end links, link attachment, clasp micro-adjust.

Two listings sell the same GMT: the SN015-G (V2) with a choice of standard folding clasp or the new hidden clasp of the SN015-G-C, and a separate SN015-G-C listing with the hidden clasp only. Specs and prices are identical: Hangzhou 6460, 316L, 40.5mm, 48mm lug-to-lug, about 13.5mm including the sapphire crystal (AR coating not mentioned), 20mm lugs, fully lumed ceramic bezel insert in red and blue, green and black or blue and black (direction and clicks not stated; image file names say "bidirectional"), enamel black dial, lumed steel hands, BGW-9 lume, 7mm screw-down crown, screw-down caseback, solid jubilee bracelet 20mm tapering to 16mm, 200m. The clasp type is left blank because the watch is sold with either a folding or a hidden clasp, at the same price. No weight is given. Blue and black is $379, the other two $399, with or without the logo. The cyclops over the date is from the photos and image names. The Pepsi, Sprite and Batman-style bezels on a jubilee bracelet are the GMT-Master II's, kept as inspired_by. Every variation of both listings showed "Out of stock" on 2026-10-24, so production status is unknown.
