Cal 83 IWC

International Watch “Detective”

The IWC Cal 83 was produced between 1939 and the early 1940’s and regarded as a transitional movement between the pocket watch and the wrist watch. I also note that this case style has straight sides and straight thin lugs and appears to have precedent as it’s reminiscent of No 58 and some others in IWC’s 1941/2 Blue Catalog.
