Hello all. I recently purchased what I though was a Seiko 5 project watch. The case back says the movement is a Seiko 6309- 7200 movement. However when I removed the works (and disassembled) it was not a 6309, at least I don't think it is. FE 5612 is stamped on the movement plate and when I looked that up I found pictures of the exact movement on the Ranfft Watches site. So I guess I have two questions. First did Seiko use this movement on their watches and somebody perhaps changed case ba
