Thank you for viewing this item. I am selling a SEIKO game clock used for Go, Shogi, Chess, etc. My father used it in a Go club, but I am selling it because the club disbanded. It is a personal item, but it was used in the club, so "Go Room No. 3" is written on tape on the back of the clock. Please see the photos. Please refrain from purchasing if you are concerned. There is no instruction manual. I have confirmed that it works with batteries. SEIKO, the color is navy. There are no noticeable scratches or stains, but it is a used item. Please refrain from purchasing if you are concerned. Batteries are not included. I will put the clock in its box (last photo) and then ship it in a Yu-Packet Plus box. Thank you.
