Omega Speedmaster Professional. This is a rare model with a see-through back. It's a famous watch modeled after the Apollo 11. It comes with everything: the guarantee card, box, instruction manual, three extra links, etc. It's a used item, but the degree of use is quite low, so the condition is quite good. There are no noticeable scratches, and it has never been dropped. It has been carefully stored in a dark place. I will pass it on to someone who will cherish it, as I no longer wear it. The surface of the box and card case has cracked due to aging, but there are no problems with the main body or links. It is a manual winding watch. It has not been overhauled, so if you are concerned, please have it overhauled. It has been authenticated, so you can purchase with confidence. The price is increasing day by day, and it is expected to continue to rise in value, so I will not accept price negotiations. 3N (No returns, no refunds, no exchanges) strictly enforced.
