Hello,

I’m a uk based watchmaker mainly working on early verge escapement pocket watches. Although they are, in principle, a lot less complicated than modern wrist watches there aren’t any spare parts available, so I end up having to make from scratch or adapt something.

I’m now starting to learn a bit more about wrist watch work, mainly vintage watches, so have joined here for some tips and information. At the moment I’m cleaning and repairing my own Universal Geneve polerouter date, with a lovely caliber 69 microtor movement. 

Thanks for reading!

Hi wildboar, welcome and keep it up !. Nice hobby but can be a bit trying at times. I have almost given up on an old verge watch. Trouble is that I did not get there first.!! Regulator plate screws missing and balance seems a bit too worn. Cleaned it and assembled then chain came off so it is back in the junk box !. Maybe later, who knows !. Best regards, Mike.

I usually wind the chain on last. I wind it onto the fusee then hook it onto the barrel and slowly wind it off the fusee onto the barrel using a watch key on the square on the barrel arbour. Of course make sure that the verge and balance are out of the watch are out when you do this! It’s then just a case of getting everything set up and in beat....

Thanks wildboar. I have torn it down again, you gave me the inspiration.  I will "make" the missing screws and put it together after further inspection. I have put the escape in the correct position but now need to check the balance bearings, particularly the one that goes thru the escape into the bearing there.  My method of chain assy is to fix and wind the chain round the barrel first and then hook the other end in the fusee. Then wind a little tension to keep it there and stick a dressmaking pin thru the contrate "crown" wheel if you like to hold it there whilst installing the balance and paddles. Fit regulator, pin h/s and  install balance bearing plate and then remove the pin. I hope to have better luck next time. Thanks again for your comments. Regards, Mike Nr. Soton UK.

G'day Mike,

It's been a while since you posted, but this is the way I was shown to stop a verge drivetrain.

Fold over the edge of a piece of paper and cut a dart out of it.

If the point of it is too long and fine I snip it off.

Then poke it through the contrate wheel. Can't cause any damage as it's structure is way softer than any of the components.

One of the old texts I have, as a PDF, by Berthoud, says to stop the train by means of a hair or piece of paper. I'm wondering if the hair he's referring to is pig's bristles? They were in use for all sorts of things back in the 1700's, and would be stiff enough to do it. I use them as needles on the threads I hand sew my shoes with, and they are very resilient things :)

Hope this was helpful.

Cheers
Duncan

      Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!

      Gamblin Gamsol for cleaning?

      By joelcarvajal · Posted

      Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?

      Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.

      Movement inserted from crytal side

      By Zedster · Posted

      Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?

      Main spring

      By nevenbekriev · Posted

      Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
