About this entry
80% of key specs known. Missing: weight, hardening, bracelet offered.
Cushion-case racing/pilot chronograph made with The League of Microbrands to re-case the ST19 from Hemel's Air Support series; also sold with a Peacock SL4617 automatic (Sky Racer (SL4617)). Brand specs: Seagull ST19 hand-winding caliber; 316L polished and brushed case, 43mm, 49mm lug to lug, 14mm thick, 20mm lugs, 50m; screw-down engraved caseback with sapphire window; signed push/pull crown; box sapphire with AR coating (side not stated); 120-click rotating bezel with ceramic insert and BGW9 lume; sandpaper-textured panda dial with BGW9. The Time Bum confirms 43 x 14 x 49mm; no source says whether the 14mm includes the box crystal. The store lists the four colourways both in one listing and as single listings with the same SKUs. The Time Bum also reviewed a Full Lume White colourway that is no longer listed, and describes a tenths-of-a-minute outer scale on most dials. Leather strap. No weight published or found.
