Watch is very rare in this gold model. The PanAm was made for pilots back in the 40s and was one of the first of its kind. Watch dial and crown were replaced at some point way back when I’m assuming around the 60s. These dials and crowns are relatively inexpensive and would be an easy fix for a watch. Watch is running though I have not timed it for accuracy and recommend a service by a watchmaker as I don’t know when it last was.
