    • That's great advice - thank you. What do you use to polish the function?  On a related note - I would assume it is equally important to obtain a mirror finish on the surfaces of the hammers and the hearts for the chrono wheels. Would you use the same technique?? Regards, Stu
    • They usually are so brittle so if you don't want to buy one I think making one is the best alternative I think, will take an hour or two but is faster than ordering em. The thing with that minute jumper I guess is that it sometimes will not work correctly, people then tend to bend them to make them "stronger" and they crack, but if one think about it they worked fine as they came from the factory and probably never will lose their springiness. The trick to get them into shape again and get a snappy  minute tick is to polish the faces of the function ( the part that goes inbetween the gears), this should be mirror polished. Often one can see it is neglected when servicing this beauty.  On the valjoux 72 version 1 it is fixed into place by two pins and should not move. On the version 2 it can be moved up and down by an excentric wheel.  Both are fixed in place with one screw when in position.
    • Thank you - these parts are so very delicate so it's not surprising that after many decades and however many services that they break. The one I have is slightly fractured and a bit of a twist at the fracture as well. I wonder if there's a way to repair it? I fear that an attempt to solder it will just cause it to break from the heat.  This is the exact same watch as Mark's video: https://www.youtube.com/watch?v=pFOQm9sAzE8&t=932s. He runs into the exact same issue. Mark chose to make a replacement and was kind enough to record the whole process. I am leaning towards doing the same. In Mark's replacement, I do not believe that he created the alignment pins to the part. I am curious as to whether or not this is a concern as I would not want the jumper to move over time. I was thinking about ensuring the new part was in very close proximity to the balance cock and/or the chrono bridge to prevent rotation.    
    • Most of the cylinder watches are not worth a lot.. to be fair, some are quite nice but many are not, and as said, most repairers don't repair them. Over in the UK it's not so easy to sell a cylinder pocket watch to a dealer - working or not.. it seems people just don't want them for the most part. A gold example is nicer but still not highly prized unless particularly rare or special. Rare would be something early/ fitted with a ruby cylinder / a watch with a complication. I've got a load of cylinder watches but most don't work and aren't worth repairing (the working ones are often terrible timekeepers by modern standards - maybe 10 minutes a day) - one or two would be pretty enough to make a nice gift for someone who's just into that sort of thing.   The watch in your pictures is actually sort of nice but the gold price is really high at the moment so it may be more expensive than that type of watch may usually dictate - due to the gold content.
