So I have this Chinese movement, it's really nice, horrendously overoiled, partially my fault when I first got interested in watches. Now I took it apart to see why it was acting up. I'm different positions it would either gain a few minutes a day or lose a few minutes so I wanted to get it working nicely again like I had it.

 

I think the escape wheel moved while I was disassembling. I reassembled and it won't move. Any help is appreciated, just want to make sure my assumption is correct before disassembling it again. If it's an easy fix then I'm hoping not to disassemble it because it's a pain.dce62fd789bb67e2200a528b4a89721c.jpg080187d48746a9b598ac3efb55edac52.jpg6207e1d7cc66fd2644978d93d854b10f.jpg

Are you sure that you have all the pivots installed correctly?

If you have a wheel out of place and one side not in its pivot hole that would stop it working?

No the pivots are fine, that one is shorter to fit into the train bridge. Everything meshes good, it all runs but it's like the escape wheel isn't properly locking with the pallet fork. When it's out together all the gears run fine, the balance wheel ( it's open heart) spins nicely, the pallet forks move but the escape wheel doesn't seem to want to. It will Rick back and forth in the pallet fork.

Is the train bridge on too tight? Or perhaps did something get into it? I've taken it apart and reassembled twice. The only other thing I don't have the oils yet. Is it that much of a difference? It was overoiled.

My goal was to be able to properly reassemble then make it a hand wind because it has that and leave the rotor off. Thanks again for any help. If you require more pictures I will try. My camera is very finicky.

Do you have the palate fork upside down?

It was because the train bridge was too tightly screwed down. I unscrewed one of the screws a bit and it started right up. But then it spun out completely so I removed the train bridge to see if any damage was done and got lucky, then I went to replace it and lost both the screws! I'm furious with myself for being so careless. I finally had it too. Can I just buy like one of those sets of screws on the bay? Will it be in there you think?

Hi Mattaphysics,

The train bridge screws are supposed to be tightened fully. If the watch works when a bridge screw is loosened then there's a problem. I would guess a bent pivot.

You need to remove the balance and pallet fork, wind the barrel a bit and observe how the wheels move. If you can't identify the problem wheel then you have to dismantle everything, install one wheel, tighten the bridge and check that it moves freely when blown with a dust-blower. Check all the wheels and jewels.

    • 🤔 leaving the EU meant that UK was no longer part of the convention and have already been turned down an independent reapplication. I'm pretty sure courts have to be held in Switzerland in this case. There will be a lot more watches stashed away in draws  tbh, folk wont be able to afford to maintain them. Cheap watches will be bought and top end watches by folk with plenty of cash that can pay for service and repair. The expensive once in a lifetime gifts and everything else inbetween will be at the forgotton when they stop working. I know i was being a numpty, get used to it 😄
    • although not in this case.  It was the Lugano Convention and its deficiencies that allowed a Swiss court decision in the first place.  This isnt really a Brexit issue at all.  A decision that affects both the EU and the UK should never have been heard in Switzerland. I bet the authorised service centres in the UK are pretty pleased.  It's a massive shame, though; I believe watch owners should be able to choose to have their watch serviced by whoever they trust.
    • Hi guys I think that old hippy is correct, it opens the gates for china to manufacture aftermarket spare parts. considering that they already do work on behalf of the Swiss I guess this decision gives the a little more legitimacy to tool up and I am sure they will take advantage of the situation either with or without the blessing of the Swiss watch industry  Having read about the protectionist machinations of the Swiss in the history of Europe they were the only ones to get fat at everybody else’s expense. I think the outcome could have been guessed at but ,  fair play to Cousins UK for standing up to them.  Now the question,  will everybody boycott Swiss watches and Swatch, no way they will still fill their coffers.  Me I stick with the Japanese once renowned for cheap shitty watches who came good through industrial effort and don’t for get the Russians that most dismiss as low grade crap. Wouldn’t buy a swatch product ever how about you all.? a
    • Hold the crown when in winding position, move the click away from the crown wheel, and then while holding the crown let it slowly unwind. I recollect that you must remove the automatic device bridge first, but maybe I'm wrong. You can first try without removing the automatic device bridge.
