Thank you for viewing. This is an OMEGA Seamaster wristwatch. Serial: 1036 Automatic winding Wrist size: Approximately 18cm It has been appraised at a nearby買取専門店 (kaitori senmon-ten, a store specializing in buying items), so it is definitely authentic. According to what I was told, it's a piece from the 1960s, and the belt is also genuine, making it very rare. I was even told that the dial is in very good condition, without any stains or spots. There are fine scratches on the case, belt, and crystal. *Please refrain from purchasing if you are nervous about home storage. *There may be small stains and scratches due to aging. *The outer box may have discoloration, stains, and tears. *Please judge the condition from the photos and purchase only if you are satisfied. *All accessories are shown in the photos.
