Compact 37mm vintage diver, listed since June 2024 (product handle "bb54"); the page compares it with the Tudor Black Bay 54, and the code follows Tudor's 1954 Submariner 7922. Brand specs: Seiko VH31 sweep quartz, 316L steel, 37mm without crown, 45.5mm lug-to-lug, 11.4mm including the crystal, 20mm lugs, sapphire with 5-layer AR coating (side not stated), 120-click unidirectional aluminium bezel (a steel bezel on the Light Blue and Pink dials, per the page and SKUs), signed screw-down crown, brushed screw-down caseback, 200m, solid 316L bracelet 20mm tapering to 16mm with a new applied-logo milled clasp with 5 micro-adjust holes (16mm buckle; OTF clasp sold separately). Lume is "C3 green / BGW9 blue" without saying which dial gets which; the latest C3 version has warmer, yellower markers. Every dial comes on a 3-link bracelet ($119) or a 5-link jubilee-style bracelet ($129); crossed-out $149 not recorded. Sold out on 2026-10-24: Black with Benz hands on both bracelets, and Red Bezel, Deep Ocean Blue and Green Bezel on the 5-link bracelet. Weight is not stated.
