My friend has a Longine's Five Star Admiral Doctor's Watch. It runs as soon as you move the watch, and keeps great time. I am looking for any information to help him out, as the only thing I can find online about it is that is it uncommon. He knows it is at least 50 years old, and the band has since rotted away. Please let me know any information on this watch (years manufactured, value, etc.). Thank you so much for looking and for any help you can give me!
