Longines 9l rusted pallet fork help


Recommended Posts

Hello everyone, I have a Nice long Jean watch with an 8L movement that got rust on it. I have a spare movement that had a broken pallet fork. The pallet fork in the original has some rust on the pivots but it does swing. I'd like to transfer the pallet fork to my nice donor movement. The question is is it safe to put the pallet fork into a rust remover solution, will it hurt the shellac on the pallets. What would you guys recommend I do to use the pallet fork.

Depends what rust remover you are going to use. Have you tried using a very fine small emery stick or the cloth. If the rust is only surface you could also try a fiber glass scratch brush, but if its embedded your best bet is a replacement.

    • Chief- The picture below shows the three parts from the dial side that are most useful to "fingerprint" a movement in conjunction with the diameter of the movement.  That's why forum participants are always asking for dial side photos in posts asking for identification.  As far as the setting lever screw, it actually sits loose in the main plate. The threads engage the setting lever below, and the elongated stem above the shoulder sticks through a hole in one of the bridge plates so that it's held captive if unscrewed all the way.  So you may be fine as far as that goes. 
    • So I found what I believe is the setting lever screw! Am I right in thinking the screw next to the click is the correct one for the setting lever? However if it is, it doesn't fit in the hole which I believe is for it! I can get the lever to sit nicely on the stem and line up with a hole, but the screw only goes as far as the shoulder and stops. It's as though the hole is too small! The dial side has been disassembled by the way, the other wheels are in my tray
    • 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
