Info needed: vintage, solid gold cal. 8531

Jun 25, 2021,15:21 PM
 

A gentleman who knows I'm into watches came by with this beautiful IWC. I think it's gorgeous!

Looks to be early 60ties, with a stunning bracelet, calibre 8531, 18ct solid gold, 34mm, I believe ref. 603, but I'm not sure.

Can anyone shed some more light on this? Production date, price range now and then, numbers produced,...anything

TIA!

Kind regards,
Bart
