Mission-timer chronograph after the concept Sinn introduced with the EZM 1 (Timefactors' description), listed in August 2022. Only the running seconds (at 12), the centre chronograph seconds and the centre 60-minute counter (aeroplane-tipped hand) are used; the movement's other counters and date aren't shown (no date window in the photos). Movement: ETA 251.264 BD with 27 jewels and a 394 battery; Timefactors says the BD suffix means PreciDrive and PowerDrive with a typical accuracy of ±10 s/year, and the chronograph has a split/lap function. Product page: 316L steel, bead-blasted or full DLC, 40mm (43.4mm with crown), 44.5mm lug-to-lug, 14.5mm to the top of the crystal, 22mm lugs, anti-magnetic to 20,000 A/m with an anti-magnetic cover, 100m, 170g on the bracelet, screw back; 120-click unidirectional bezel in steel or ceramic with luminous triangle and numerals; flat sapphire with AR on the underside; semi-matte black dial with Super-LumiNova C3 hour indices and 3-6-9, white lumed hands. Bracelet in steel or DLC with custom solid end links, screwed links and an adjustable twin-pusher clasp (adjustment type not stated). Made in Hong Kong. The page says "Now sold out" and every option was unavailable on 2026-10-25, with no word on a restock, so the status is unknown. The DLC is listed as a finish; whether it hardens the case isn't stated.
