About this entry
79% of key specs known. Missing: weight, hardening, bracelet links, end links.
Brand specs: 316L steel, 40mm (the brand says this is the bezel measurement and gives no separate case diameter), 46.9mm lug-to-lug, 13.95mm including the domed sapphire crystal (11.6mm excluding it), 20mm lugs, "High Clear AR Coating" (side not stated), fixed aluminium bezel, BGW9 lume on dial, hands and markers, screw-down crown with two pushers, brushed screw-down caseback, 100m. Bracelet: "Push-Pin 316L stainless steel", 20mm tapering to 16mm, with a milled safety clasp with five micro-adjust holes. The store also sells a screw-link replacement bracelet for the WD1860-WD1863 and a rubber strap separately. Black dial $105, white $109 (no crossed-out price). No date window on either dial (the VK63's date is not used); the 24-hour register at 3 is the movement's built-in indicator. Homage: the store SKUs name the Speedmaster (超霸). Weight is not stated.
