Folks, I have a 7C43-7009 case, bezel, case back etc - in fact everything bar the movement. The watch was a Seiko sample case. I am thinking of doing a TST mod to it, but need to know what movement would fit into the case. Would a 7C46 movement fit? I understand the 6309 / 7548 cal movement fit, but what others? I read a thread where a Pulsar movement was also fitted but it needed another case back.
