This is a vintage men's Waltham watch (XAX71-136) with a gold-colored dial, hour indices, and hands. The dial also features a diamond accent at 12:00, just above the Waltham logo. The movement is from Japan.
The case and band are gold and silver colors. The watch is "NOS" and still has its tag as well as the little spacer between the case and crown, indicating the crown has never been pushed in.
The watch is untested. I do not know if it works. It is very clean and the watch shows no signs of wear. Very strangely, there appears to be a pin missing from one link in the band. I've tried to show this missing pin in the last image. Let me know if you have any questions!
The watch comes with the box and booklet. The watch is sold as is and the price includes domestic shipping!
