Hi guys,

I was given a Zenith alarm pocket watch to have a look at, the watch runs fine, but when the crown is set to the hand-set position, the hands do not move, only budge slightly, and you can feel quite a bit of resistance.

I removed the movement from the case and inspected the keyless works, I attempted to remove the cannon pinnion and it is quite stuck, I've tried both my presto tool and canon pinion remover, there seems to be no budging it.

On closer inspection you can see some rust at the top of the cannon pinion, and also mid way down the metal seems to have degraded somewhat and more rust is visible.

Is there any chance of getting this removed? I've tried a little bit of oil but it seems to make no difference.
 

Thanks in advance!

The cannon pinion is a unusable cal shape it almost looks to have been squeezed in a lot. Wondering if a previous preparer have tightened it while in situ. Do you know the calibre 

I do know from the volume of 3in1 oil that has leaked onto my workbench, that the previous visitor to this movement was fairly clueless.

This is the calibre, http://www.ranfft.de/cgi-bin/bidfun-db.cgi?13&ranfft&207&2uswk&Zenith_19_Reveil

I don't think I will have any luck finding parts for it...

      Gilding after silver soldering

      By AlanB · Posted

      When faced with say a pocket watch bridge which is cracked, silver soldering to repair is often the only option (hopefully someone wasn't there before hand with soft solder). I can generally do this succesfully and tidily with a small torch and miniscule pieces of silver solder, but on parts which were mercury amalgam gilded the heat can have have a deleterious effect on the finish.   I keep wondering if there's a good way to refinish these - and despite having the needful items would rather avoid using the mercury process.   In the past for electronic work I've gold plated PCBs but this involved gold potassium cyanide solution, which also doesn't realy belong at home. I've read that there are now safer alternatives but couldn't find more detail (and importantly how similar are the results to amalgam gilding, since I wouldn't want to refinish the whole watch). Pointers would be very welcome (and yes, I know solutions containing gold won't be cheap!) Alan

      Ok so with the great answers for my previous question may I ask what these two attachments are used for. The one with the red knob is I assume used for hand setting the seconds hand? Jon

      Roamer Searock Crystal problem

      By Zedster · Posted

      According to Cousins site I need to look at document G22 as I think I need an ATGB at 304 but I cant find this size in G22 doc. The last thing I want to do is order the wrong one😳  Unless I cant see the wood for the trees 😆 I could be looking at the wrong style, I assume its classed as Round plastic Armed  https://www.cousinsuk.com/product/wide-ring-gold-atgb

      Dial feet removal

      By JonC · Posted

      When building a new Watch I have tended to use a file to remove the remnants of dial feet that are not needed as many dials come with four feet to accomodate different movements, but this can be a bit messy so now I use this with a great deal more precision as you can use an appropriate bit for the job and keep it very localised.
