Looking to sell my February 1972 (serial number 220848) Seiko 6139-6012. This chronograph works great and all of the pushers work as they should. The Chrono snaps back to the 12:00 position and it keeps very good time. I have worn it all day and it is right on the minute. The crystal is in great shape and I do not know if it was replaced. Minor scratches on the watch due to being 50 years old. There are two knicks by the right lower lug (see picture) I bought the watch in 2021 from a watchmaker in Atlanta. He picked it up from a client who had it a long time. He serviced the watch and showed it to me as I was getting another watch band shortened. Needless to say that I was hooked and bought it. I am asking $400 OBO for the watch which includes shipping to CONUS (only) via USPS priority mail. Zelle is preferred but I can also take PayPal G&S (buyer assumes any fees) or Venmo. I will ship as soon as payment clears. Here are the specs Reference: 6139-6012 Complications: Date, Weekday, Chronograph, Tachymeter Features: Luminous hands, Luminous indices Bezel Material: Steel Dial Color: Gold Case Material: Steel Dial Numerals: No numerals Crystal: Mineral glass Case Diameter: 39mm Lug Width: 19mm Movement Type: Automatic Frequency: 21600 bph Number of Jewels: 17 Power Reserve: 45 hours Movement Caliber: 6139 Verification photos, pictures, and videos can be found [here](https://imgur.com/a/XBhlDPc) Let me know if you have any questions.
