I am selling a recently acquired IWC. I think I'm satisfied with owning just one good one. You're looking at a 1960's Tiffany and Co Signed IWC watch, with a caliber 8531 movement. The movement is a higher grade than most 8531's, being five times adjusted, as specified on the movement. As with all 8531's, it also has a microregulator. Keeps very good time. 34mm, excluding crown. $2,050 OBO via Paypal + Shipping
