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 movements fit, but do any others fit?

I read a thread where a Pulsar movement was also fitted but it needed another case back.

Alternately, any 7C43 movements gathering dust out there?

All things 7c43 are rare now.
Personally I wouldn't TST it, not when 6309-72xx are so abundant or even 7548-7xxx if you wanted quartz.
People would frown on that mod too but less scarce than 7c's
Plus when done, especially if modded you'd hardly tell the difference and probably no difference in value later on either.
The doner watch was a sample case and the case back is stamped SAMPLE. I have swapped the almost NOS case itself for another one of my 7C43 watch cases that was pretty banged up. Hence me being comfortable in using the case remaining for the TST mod and the sterilising of the case back will remove the sample stamp.
