Listed in October 2026 as an update of the WD1863 with the same case, VK63 movement and domed sapphire crystal; the change is a new three-link bracelet (20mm tapering to 18mm, "tighter tolerances and reduced lateral play", from the original bracelet supplier) with an on-the-fly adjustable clasp. Brand specs: 316L steel, fixed stainless steel bezel, matte black dial, 39mm bezel on a 41mm mid-case (41mm recorded), 46mm lug-to-lug, 12.9mm including the domed crystal, 20mm lugs, "High-Transparency Anti-Reflective (AR) Coating" (side not stated), screw-down crown, screw-down stainless steel caseback with brushed finish, 100m. The lume line says "C3 Luminous Material (C3 versions only)"; the only option is Vintage Black, which matches the WD1863's C3 "Vintage Black" dial and shows vintage-tone markers in the photos, so C3 is recorded. The VK63's date is not shown on the dial. Homage: the WD1863's store SKUs name the Speedmaster (超霸). Weight is not stated.
