IWC Calatrava Cal. 89 1960s

The IWC Caliber. 89 dress watches of the 1960s represent a particular moment in Swiss watchmaking — an era when function and form were held in careful balance, and when a dress watch was expected to disappear beneath a cuff as readily as it commanded attention across a table. Produced in Schaffhausen from 1946 through to 1979, the Cal. 89 was IWC's workhorse manual wind movement: robust, reliable, and housed across a range of case configurations that evolved meaningfully across its three-decade production run.
