Hey guys. I'm finding technical sheets of the following seiko movement: 5740C and 4s28. If you know where I can access to these files, please let me know.

BTW I'm planing to sort of 'DIY' a wrist watch use these two movement and dial strip down from pocket watches. If you had work on any of these movement, please leave a message I‘ll contact you privately if that‘s OK.

Thank you guys.

Peace

not a lot of information out there at least not that I'm finding. I found a couple articles on each of the watches. I did find a 4S15 sheet not the same one you requested but it's in the same family hopefully it's helpful. Then I did find the  the other one working on my computer no idea where it came from? As conveniently looking online I didn't find one.
