About this entry

Hemel's 40mm hand-wound ST19 pilot chronograph line, which the brand calls the Air Support series (store collection "HF Series Air Support"; the Sky Racer page refers to "our Air Support pilot series"). The store sells it under separate names (Air Defense, Air League Special, Air Wing, Airfoil, Air Power, Air Strike, the Hawkeye Chronograph made with Long Island Watch, and a Widget Watch Club project); every listing gives the same case, movement and crystal, so they are recorded as variants of one model. The 42mm Airfoil option is a separate model (Air Support 42mm). Brand specs: Seagull ST19 hand-winding column-wheel chronograph (the Hawkeye and Air Wing pages specify the swan-neck regulator version), 45-hour power reserve claimed; 316L polished case, 40mm, 47mm lug to lug, 20mm lugs, 100m; screw-down exhibition caseback (sapphire per the Hawkeye and Widget Watch Club pages); signed push/pull crown (not screw-down); double-domed sapphire with AR coating (side not stated); 120-click rotating bezel with C3 lume. Thickness 13.4mm is the brand's figure on the Air League, Air Wing and Airfoil pages and matches The Time Bum's figure for the Air League; no source says whether it includes the crystal. Bezel direction is not stated. Bezel insert and scale vary by variant (black ceramic 60-minute or 12-hour, steel, orange aluminium); scales are read from photos where the brand doesn't state them. Lume: C3 on most dials, BGW9 on the Air Power, the full-lume Hawkeye dials and the Widget Watch Club; bezel lume C3 throughout per the listings. The Air Strike adds a tachymeter scale and a jumbo crown (Hemel also sells a "Large Air Support Crown Upgrade"); the Air Power has a big-eye subdial. Leather straps (Italian leather per the Air Power and Air Strike pages); a separate Air Support Commander Bracelet is sold as an accessory. The Widget Watch Club version was a $800 made-to-order project for club members (five to six months' lead time, all sales final), shown only as a rendering; recorded as limited, number not stated. No weight published or found.
