IWC 32111 (Sellita SW300-1 base)
IWC(base: Sellita SW300-1)
IWC's slim automatic caliber based on the Sellita SW300-1, itself a clone of the thin ETA 2892-A2. IWC extends the power reserve to an impressive 72 hours through mainspring modifications. The slim 3.6mm profile makes it ideal for dress watches like the Portofino, and it carries IWC's rigorous in-house decoration and testing standards despite its third-party base architecture.
