Well, the car was equally ancient and bashed up anyway
Seiko 6139-6020, from 1979. Quite a common old classic but i like the pepsi bezel and black dial on this one (some are horrible 70s gold)
Chrono pushers and chapter ring stuck (common problems) but otherwise looks pretty original and intact, keeping fairly good time.
I plan to send it away for complete restoration. Removed the bracelet and put it on a Zulu, been wearing for the last 2 days.
