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.

      Can someone please explain watchmaker service mark interpretation?

      By HorologyHead · Posted

      H Watch Repairers—is there is a ‘standard format’ for the service marks or codes lightly engraved inside cases of pocket watches or wristwatches?   Sometimes I can see there might be a reference to year/ month but other times am confused. I’ve included an image of the rear of a 1951 Hamilton 992B Railroad pocket watch as an example. Thank you for all information you can give, Mike

      Hi to Blackminou29–am a collector/ caretaker—good luck to you following your repair course—with hindsight I wish I’d pursued a career in both watchmaker/ jeweler fields—good luck with whatever career passion you engage.   Thank you Watchweasol for posting the amazing TZIllustratedGlossary! Best wishes, Mike

      Seiko 6601 Tech Sheet?

      By JohnR725 · Posted

      yes I noticed the new site and I miss the old site. It's the unfortunate problem of the Internet here today gone tomorrow sometimes some of the stuff gets backed up and sometimes well it does not then the problem with the early Seiko's were there were not necessarily designed for distribution across the planet and as such there is no customer support for them. So trying to find early stuff like technical information or sometimes even parts list for older Seiko is is problematic. But I did find you a you tube video. A quick look he seems to take a heck of a lot of time to actually get to the service single I did not watch all that but it does look like he did disassemble or started to say there's a tiny bit here

      An intro…

      By HorologyHead · Posted

      RichardHarris123: Hello and welcome from Leeds, England.  I have family all over Australia, went as £10 poms Thanks Richard. Hope you’re able to visit your family here and that they’ve all done well 🙂 My relatives arrived from England in the 1790s transported on the ‘Second & Third Fleets’—a story of timber sailing ships, of convicts and doing well in this huge Country of Australia. When I visited the UK in the 1980s, I was too young to comprehend the depth and breadth of its history…  Best wishes, Mike William Chapman, my 4th great Grandad’s charges, at age 23 read at the Old Bailey; sentenced to 7 years of transportation to Sydney.

      New balance staff not riveting to balance

      By Endeavor · Posted

      The whole process and the progress are closely observed, it's hand-driven and very controlled. I can't see the "danger", unless you are watching the TV while doing it. As you could have read, and in this quote "wheel" is the balance-wheel.
