Please help identify movement UT 36-CA

[jguitron]

I have a vintage diver with a broken stem. I have been searching for quite some time for any reference about the movement.

 

The closest I’ve got is that it may be interchangeable with a Seiko movement, but not sure what model.

 

I don’t think it’s Unitas, it’s not in the bestfit encyclopedia. Not UTC either.

 

Please post any info that could help me get out of the ditch.

 

Thank you!

 

Here’s a pic from the web:

Hi  From what I can gather from other sites It is a Unitas but data on the 36-ca seems scarce. I will have another look as time permits.

Really need a few more pics to identify.

Thank you. Here a few more.

There’s a T and 328 identifier under the balance.

The construction looks like a Seiko 7625 e.g. http://www.ranfft.de/cgi-bin/bidfun-db.cgi?11&zenoshop&0&2uswk&Seiko_7625D

It's an earley Seiko movement. Hence the seiko shoksprings . Not supercommon.  http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&0&2uswk&UTC_233

The 6601 itself is based on the manual Cal.66, might be helpful if your looking for parts.
