Like OHSaid some of the cheaper ones do not adjust. I have used the method shown to open up the grains of rice and refitting, time consuming but can be done but mind your fingers. Best done in a block to support the bracelet. -

All I could find, there might be a small indentation as on a snap on case back to insert a blade between the case and the rivet. -

Hi all. This is my first time I disassembled and assembled a movement. My project consists on building a Seiko 6349A. I have all the pieces I need. Most of them come from a donor movement, the 6309 which is running and most of its pieces are compatible. The ones that aren't I have them from the 6349. So, the 6309 is working, so I disassembled it. I started assembling the 6349, everything was OK. I managed to install most of the pieces, until the train bridge. I wound the movement and it worked. It "hisses" for quite a while and all the wheels rotate well and fast. So, I picked up the fork and installed it. I put its bridge, wound the movement a bit and tried the peg wood trick on the fork to see if it "snaps". No, doesn't happen. It moves if I push it with the peg wood, but it seems it's not getting any power at all. Of course I won't bother to install the balance until I fix this. All these pieces were working under the 6309, so I assume they're OK. What do you gents think? Thanks -
You will find with the cheaper bracelets there is no way of removing links. -
In fig 2 you can see the washer which is press fitted, press it back with .01 mm tolorance to the balls of the bearing, obviously theres a risk of damaging the balls in the bearing or deform the washer if you punch. Support the other side of the bearing on a anvil.
