The present IWC caliber 83 has remained in remarkably good condition since it left the factory on April 7th, 1942 and sold to Weinstabl, Prague. While the case has seen at least one sympathetic polish it retains its strong proportions and clean line. The dial has aged over the years and turned a lovely golden brown hue, which is uniform throughout, giving the watch a star quality. The hue of the dial is perfectly complimentary to the stainless steel. This is a rare chance to own a watch from the 1940's that has been well maintained and with the rare tropical dial.
