This is a VINTAGE GOLFER'S SCORE KEEPER that is Mechanical. The color is Black and Silver Tone and it was made in Hong Kong. I'll be honest. I don't know much about GOLF. I do know this counter is made to keep a tally of your strokes using the click of a button. All three knobs work to turn the dials back to zero. There are some scratches from wear on the front which make it all the more interesting. The band is in excellent condition and is original. This is a pretty low tech option for keeping score. Pick up this little bit of HISTORY and keep your golf game accurate. Check out the other items in my eBay store. You might just find another treasure!
