This is a SEIKO 7T36 6A30. I purchased it in Hong Kong around 1996. I used it quite frequently, so it has some scratches. Please check the photos and make your judgment. I have lost the box and instruction manual. Also, the battery is dead, so you will need to take it to a watch shop to have the battery replaced before you can use it. I will include a box from another watch for shipping, so please don't worry.
