I have a Seiko 7005 movement that I have taken apart, cleaned, oiled and reassembled. It would stop running when I placed the hands on it so decided to service it.
The hairspring seems to move freely but it will not start running. I've seen no issues with any broken parts and when the hairspring it bumped or hit with a little air, it will move the pallet fork and the escapement wheel will move a few ticks, then it all stops again.
I've wound it quite a bit (it's an automatic) but nothing seems to get it going.
Any ideas welcome. Thanks in advance!
