Very nice IWC Yacht Club International Watch Company Schaffhausen Swiss. All stainless steel original folding clasp IWC band. Watch is mechanical automatic reference 811. I wear this watch often keeps excellent time with a big reserve. Case is 36mm, band will adjust to a fairly large wrist. Watch has minor scratches consistent to age and the fact that I do wear it. A competent watch or jewelry tech could polish it easily . Dial is extra nice and and date works accurately. Really nice watch
