Thread bump. I just bought one and it's freaking awesome in a terrible way! This isn't a 70s homage or fancy reissue - this is a watch from the 70s. It wouldn't surprise me if what actually happened was someone from Orient found a basement in the factory where these things had been stored and forgotten about for the last 40+ years.
Anyway, the head itself seems pretty weighty and solid and it's keeping excellent time. The bracelet is typical 70s cheapo utter crap and an absolute pain in the arse to adjust. But hey, 70s! I shall be wearing it lots.
£118 on Amazon if anyone is interested.
