IWC 32111

High confidence

The caliber that replaced bought-in bases in the Mark and smaller Portugieser references — a significant change for the Mark line in particular, which had run on outside movements for decades. The five-day reserve is the practical distinction from the ETA-based Marks that preceded it: a Mark that stops after two days is an earlier generation.
