For your consideration is a November 1974 6139-6012 “Bruce Lee” Automatic Chronograph. All components except for the bracelet are original Seiko (dial, hands, case, crown, pushers and all mechanical components).
The watch is in excellent working condition. The case remains unpolished and is very good shape for a worn vintage watch. The dial is original to the watch and has a date stamp that is one month prior to the case date (4O — shown above). The chronograph hands reset exactly to their vertical positions. Bracelet is an Uncle Seiko branded “Railroad Style”. The crystal is a new Klein Hardlex replacement.

I serviced this watch on 09/25/2022. 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 240-250 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.
