OMEGA Speedmaster automatic chronograph with tachymeter and black dial. I received this about 20 years ago. There are many fine scratches and scuffs overall from use. Please check the condition in the photos. The operation has not been confirmed. The original belt was damaged, so it has been replaced with an aftermarket belt. (Therefore, the belt is not genuine Omega) It was authenticated as genuine when the belt was replaced. However, there are no accessories such as a warranty or box. It fits perfectly on a 17cm wrist. Due to the high price of the item, returns are not accepted to prevent switching. If you have any concerns, please comment before purchasing. Thank you for viewing.
