For your consideration is a quite rate January 1970 6139-6010 “Blue Bruce Lee” Automatic Chronograph. This is a proof/proof with its original 2-part sweep hand. All components except for the bracelet are original Seiko (dial, hands, case, crown, pushers and all mechanical components).

The dial and hands retain their original lume. The chronograph hands reset exactly to their vertical positions. Bracelet is a Seiko branded “Railroad Style”. The crystal is a new Klein Hardlex replacement.
