This is a wristwatch that was sold in-flight on UNITED AIRLine. According to the owner's grandfather, it was only used a few times, but it has been stored at home, and it's probably about 30 years old, so there is some age-related deterioration. It's a retro and rare item that is no longer available. Items from this era are durable, so I think it can still be used, but since the operation has not been confirmed, please purchase only if you understand this. Feel free to ask about price negotiations! To ensure early detection of damage during shipping and prevent trouble, we appreciate your cooperation in checking the item and providing an evaluation on the day of arrival. Returns and exchanges are not accepted to prevent product substitution. Overseas buyers and proxy purchases are welcome! * We will take waterproof measures and ship with a tracking method. Immediate purchase is welcome. No smokers, no pets. We will offer a discount for bulk purchases. #wristwatch #ladies #men #stylish #rare #double #analog #battery
