Hi All

Here's a beginner question:  an old Timex 29 movement looks to be spot on after 24 hours.  However,  it looks very erratic on the timegrapher with rate varying from + 60 to +330.  Amplitude varies as well.  I'm wondering if the timex design can be measured on a timegrapher at all??

Thank you

Charlie

Any time you get random dots on the machine then the numbers are meaningless.

So I did an experiment for you same timing machine different Timex unfortunately I only have one Timex that's running. So initially it wouldn't even display unless I set the machine to 18,000 beats per hour watch. So occasionally something resembling a pattern of dots like in the image below or totally random dots and occasional the machine resets because it can't read it at all.

I think these machines were designed for jewelled levers, so that probably has something to do with it as the sounds produced are different. I've had some pin pallets that do measure reasonably ok on mine though (including Timex).

      What is this tool !

      By mikepilk · Posted

      I was pleased to pick up a selection of some tools on ebay (v cheap 🤣), and they've just arrived,  I've been looking for a crystal press for a while, and this one is ideal But in the selection is this thing - what is it for?  (it's about 3" long) Something to do with stem tubes?

      You'll have to strip it back anyway.

      Epilame / Fixodrop

      I think I've heard that more than from just Alex. That doesn't make it right though, but I'm convinced i saw some literature diagram explaining why to do that. There must be good info here in the archives, I'll have to have a dig around.

      That will mean dismantling the gear train, which with 5 pivots to align was a pain. Probably going to have to though. I'm convinced it's something to do with the great wheel.

      By VWatchie · Posted

      As far as I know, the only time an epilame treatment has potential drawbacks is when something is rubbing on the treated part w/o lubrication in between creating abrasive dust. That is, I don't believe in the method of "running the watch to make a groove through it first in the pallet stones where the lubrication is then placed". So, I think the rule would be; do not epilame treat parts where rubbing is going on without lubrication. Other than that I don't think we have anything to worry about. That said, I'm not an expert, and I'm always happy to learn more. Has any other repairer than Alex suggested or explained the "making-a-groove" method? My impression is that it's just something he constructed in his mind. I have not perceived it as a generally practiced method. Again, I could be wrong!
