About this entry
79% of key specs known. Missing: hardening, end links, link attachment, clasp micro-adjust.
GMT-Master II-style automatic (the title says "GMT-Master") in a left-handed case: the crown, its guards and the date window (under a cyclops lens) sit at 9, as on Rolex's left-crown "Sprite" GMT-Master II, with a two-colour 24-hour bezel, an arrow-tipped GMT hand, lumed dot and baton markers and an oyster-style bracelet; the dial reads "GMT, Automatic, Water resistant 20BAR/200M". Brand specs: "Japan Seiko NH34" (Seiko NH34A, recorded; the title, the description's parameter table, a "Japan NH34A" panel and the movement photo agree), stainless steel case, 40mm, 13mm case thickness, 20mm band width, 20 bar, "AR coated sapphire" (AR side not stated), "BGW9 super luminous", stainless steel band 21cm with a "Folding Clasp with Safety". The parameter table (NH34A, AR coated sapphire crystal, stainless steel case and band, 200M, 40mm, 20mm, 210mm, 13mm, "Lug to lug 48mm", "Weight 160g", recorded as unspecified) agrees. Bezel: detail images describe a "one-way spin diving chrono lap" with "anticlockwise rotation" and "120 clicks chronograph bezel", recorded as stated (a GMT-Master's bezel turns both ways). Detail images also show a "cyclops lens", a "screw waterproof crown", an ice-blue "BGW9 luminous" display and a "bottom cover display, three-fold clasp"; the photos show a solid caseback and a fold-over clasp. Three-piece links are counted from the photos. The spec list's "Complete Calendar" is not borne out (date and GMT only). $149.99 for all colours on 2026-10-24, all sold out on 2026-10-25. No independent review was consulted.
