For your consideration is an August 1972 6139-6012 “Bruce Lee” Automatic Chronograph. All components original to this watch (dial, hands, case, pushers, crown, and all mechanical components).
The watch is in excellent working condition. The case remains unpolished and I would rate the condition as excellent vintage. The dial is original and all hands are original to the watch. The dial is the beautiful Seiko “deep blue” sunburst pattern and has a date stamp one month prior to the caseback (27 — see images). The dial and hands retain their original Seiko factory lume. The chronograph hands reset exactly to their vertical positions. This watch is listed without a bracelet or strap, but if you are interested in adding one, please let me know. The crystal is a new Klein Hardlex replacement.

I serviced this watch on 12/12/2022. That process includes a full cleaning and evaluation of all movement components and proper lubrication and the installation of two new jewels in the arbor ports (a $180 upgrade). Lubricants are Moebius synthetic varieties appropriate for this watch movement type. The amplitude numbers are 230-235 range and the rate is +/- 2 sec/day. The case back, pushers and crown all have new, and factory correct seals.
This watch comes with a 100% money back promise of originality and a 1-year limited warranty on the movement from the time of sale. Shipping is to CONUS through USPS 2-day. International is a flat fee using USPS international priority.
