You are looking at a Seiko 6139-6002 Pogue Day, Date Chronograph Automatic Wrist Watch. The bracelet is aftermarket and no extra links are included. Good crystal with minimum wear, bezel, and case does have some scratching. I am only able to get the watch run about a minute and then it stops. Repeatedly only run about a minute. Watch has been in the drawer for long time. I do not know how to set the watch, you can hear the automatic wind smooth and function. Because of the age and not able to confirm fully function, I will sell as is. Sold for part or repair no exchange no return. Please read all the description examine all photos for reference and ask questions before bidding. Picture are very important part of the description.
