About this entry
93% of key specs known. Missing: hardening.
Timefactors' first monopusher chronograph, listed in November 2021 and now marked "SOLD OUT & DISCONTINUED". Product page: 316L brushed steel, 40mm, 46mm lug-to-lug, 15mm to the top of the crystal, 20mm drilled lugs, full anti-magnetic cage (20,000 A/m), 100m, 95g including strap, screw back, screw-down crown; flat sapphire with AR on the underside. Black: matte black dial with white markings and white painted hands. White: cream dial with blue markings and heat-blued steel hands. Super-LumiNova X1-C3 on both. Movement: "Sellita SW510 MP, 27 jewels, Automatic, 28,800 BPH, 62 Hour Power reserve", linked to the SW510 file (whose base version has a 12-hour counter and date); the photos show running seconds at 9 and a 30-minute counter at 3, a single pusher at 2 and no date window, so complications are set from the photos. The store tags say "36mm" and "Hand Wound", against the specification's 40mm and automatic movement (the product type also says automatic); the specification is recorded. Supplied in a three-watch travel roll with two sailcloth straps. Price as last listed.
