For your consideration is a May 1971 6139-6012 “Blue Bruce Lee” Automatic Chronograph. All components except for the bracelet are original (dial, hands, case, crown, pushers and all mechanical components).
The watch is completely original unto itself and is in excellent working condition. The case has not been polished and shows wear commensurate with the watch. The dial is very clean but has a minor imperfection just above the hold in the sub-register. The lume is original to the watch, but has darkened slightly. The hands reset to their vertical positions (+0.5sec on the sweep hand). Bracelet is an Uncle Seiko “Railroad” that very closely matches the original bracelet style. The crystal is a new Klein Hardlex replacement.

I serviced this watch on 05/23/2022. 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 +/- 3 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.
