So had chance to take pics of the Immaculate movement. Engraved on back A44891 LR Gordon MT Gambier.... Just had newer movement fitted the other one was giving me problems watch maker said it was worn luckily he had a 6106c hacking movement it cost me way to much but without a movement there's no watch. I've been wearing this watch all morning running great good time keeping , took it off and it stopped , picked it up and it started it's still running now after an hour... I called the watch guy that supplied and fitted the new movement, he says although it's a minty movement it may need a service...The item "Seiko Vintage Sports Diver 6106/8100 Almost Mint 1968 Automatic Rare Stunner" is in sale since Saturday, February 24, 2018.
