Presented in 1993 to commemorate the 125th anniversary of the manufacture in Schaffhausen, the IWC Il Destriero Scafusia ('The Warhorse of Schaffhausen'), ref. IW1868 comprises:
- a perpetual calendar (in German in the particular example below, ref. IW1868-01)
- a flying tourbillon
- a minute repeater
- a split-second chronograph
The
watchmakers who collaborated on this piece are no less than:
- perpetual calendar: Kurt Klaus, best known for “Operation Eternity” and inventing the genius crown-operated perpetual calendar
- tourbillon and split second chronograph: Richard Habring, founder of Habring2
- minute repeater: Robert Greubel (cofounder of Greubel Forsey), Giulio Papi and Dominique Renaud (cofounders of Renaud & Papi)
- design: Hanno Burtscher, designer of the Da Vinci
- production: Lothar Schmidt, who later would take over Sinn
Exact case dimensions are unclear online: diameter is 42-43 mm and thickness is 17-18 mm. Calibre 1868 is based on the Valjoux 7750.
This particular example is in
yellow gold and
was sold as
lot 322 at Dorotheum in 2023.
Best, Emmanuel
