Breathing New Life into a Legendary Seiko Chronograph - Lessons in End-Shake

Join us as we revive a legendary Seiko 6139-6010 Chronograph from March 1970, famously associated with Bruce Lee. This 'Proof' model required multiple repairs and precise end-shake adjustments to bring it back into running condition.

Experience the challenges and triumphs of reviving this well-preserved timepiece, as I am reminded of valuable lessons about end-shake adjustments.
