The IWC Schaffhausen Calibre 89 watch is a cornerstone of mid-century elegance, housing one of the most respected manual-wind movements ever produced.
The Calibre 89, designed by the famous Albert Pellaton, was originally developed for military service (found in the legendary Mark XI pilot's watch) but transitioned into these refined dress cases starting in 1946.

It is celebrated by collectors for being built like a tank, featuring thicker bridges and heftier pins than typical dress movements of its era. This specific example features a beautiful tropical patina on the dial, where the original finish has aged into a unique green-flecked texture, paired perfectly with the premium Hirsch green leather strap.
