This is a model equipped with the famous old International Watch Co. (IWC) caliber 83. It has a large 35mm case. Furthermore, it's an Inca-type with a shock-resistant device, which was only made in the final years of the 83. The classic script logo, bar hands, and bar indexes create a simple, IWC-like combination, and the slender lugs give it a very classic and refined atmosphere. Many 83s have small cases, and most don't have shock resistance, so an old IWC that's easy to use is rare and valuable. Purchased in Europe, it has not been serviced in Japan. Currently, it runs within one minute per day, but no warranty is provided. Please consider this as a guideline at the time of listing. I've sold IWC watches like the 83/88 in the past, but they've become difficult to obtain. I hope you'll consider this opportunity. Returns and exchanges are not accepted to prevent issues such as parts swapping. Please be sure to inquire about any concerns beforehand.
