I'm new here and into watch/horology world as well. I recently tried to replace the dial on my 7750 watch.
1) Open the wathc case
2) removed rotor
3) removed stem (gentle push of remove stem pusher and pull the stem out)
4) removed the movement from the case
5) put movment to movement holder
6) removed hands
7) removed dial
8) put new dial
9) pressed the hands back, hovewer during setting it up I realized the movement is not running - even when I wind it up - it is solid/stable and not ticking at all..
Kind of out of ideas what can went wrong, the movement was functional correctly before..
Thank you for any ideas.
I'm wondering what tool is commonly used to manipulate the regulator arm? I've used everything from tweezers to a plastic stick used to help open up computers. My main issue is that all of the things I've used are risky for slippage and I find it incredibly hard to just nudge a little when you're really trying to dial in the timing. I would think there would be a special tool for this (there's a special tool for EVERYTHING), but I haven't managed to find such a tool if it exists. Today I made my own tool using an old broken spring bar tool that I reshaped that should make life a little easier, but I'm very curious to see what everyone else is using.
in order to buy appropriate spares in my attempt to service an Omega 175.0083 (7750) I need some advice:
I've already been suggested to replace MS:
Barrel is Ok and I'm thinking of buying a new MS and moebius 8217 for barrel lubricating as I don't want to spend money on recommended Kluber 125 grease.
Should I consider instead buying a barrel complete (assuming Barrel complete (180.1) comes with MS installed) wich supposedly comes prelubricated ?
Attached image shows automatic device bridge with evident sign of wear from where, to my understanding, the problem orginated: a screw came off
I cant find original part.
ETA part is different from Omega in that the Omega is larger and partially covers hammer two function and the chronograph cam.
Beside that and since the watch has no crystal back case I think those parts are perfectly interchangeable.
Do I need to replace the bridge or are there alternative aproaches to this problem?
A new 7750 movement, cleaning and assembly again, why watch swing only 260 °?

The rub-in jewels in question are those with a cap jewel held by friction or some kind of claws to secure it, no easy way to take the cap jewel out. I know the easiest way to lubricate it is just use a automatic oiller. Is there any method to oil it if I dont get an automatic oiller? Thank you!
Hey I hope I can help you. I live in China and there's a considerable amount of spare parts of 7001 taking out from the original movement including the whole barrel assembly and mainspring. Where do you live? I see if the selling can ship to you or not? As for the prize I guess one barrel assembly will be ¥100 that's around $14.
Just took a look and PUW movements in general has a crown wheel with a small bearing. And by the looks of your ratchet screw I would say it is missing the small bearing and is upside down. I just pop a picture on a common PUW ratchet wheel here so you can see what it might look like.
