Openly described by Timefactors as an homage to the Blancpain Air Command. Product page: 316L steel, brushed with polished lug chamfers, 42mm (45.3mm with crown), 50mm lug-to-lug, 13mm to the top of the box crystal, 20mm drilled lugs, anti-magnetic to 4,800 A/m, 100m, 95g on the strap and 157g on the bracelet, screw back; 120-click unidirectional bezel with a sapphire insert; box sapphire crystal; semi-matte black dial with Super-LumiNova C3 hour indices and 12 and 6, white lumed hands. Seiko VK64 mecaquartz chronograph, Japanese made; its 24-hour indicator is at 3 and the 60-minute counter at 9, and no date window shows in the photos, so complications omit the movement's date. Sold on a stainless steel beads-of-rice bracelet (£310) or a leather strap with deployant clasp (£265). Made in Hong Kong. Marked "Final production run"; both options were available on 2026-10-25.
