Named after the Supermarine Seafire, the carrier version of the Spitfire, with an aircraft-instrument dial. Product page: 316L steel with satin black PVD, 40mm, 45.5mm lug-to-lug, 12.3mm to the top of the crystal, 20mm lugs, anti-magnetic 4,800 A/m, 100m, screw back, 80g head only; flat sapphire 32.4mm x 1.4mm with AR on the underside; semi-matt black dial and index hands with Super-LumiNova C3. Movement: ISA (Swiss) quartz 9500-1010, whose seconds hand steps four times a second, CR2032 lithium battery (48 months) with end-of-life indicator, and an unconventional time-setting procedure; no ISA spec sheet was found, so no movement file was added and only the type is recorded. No date (dial photos). 20mm custom "Seafire" NATO strap. Case made in Germany, movement Swiss. Marked "Final production run"; available on 2026-10-25.
