Can you buy chronograph pusher extensions?


Recommended Posts

Hello everyone!

I am working on a Chronographe Suisse with a landeron 48 movement. I had to replace the pushers since the original ones were in terrible condition. However, the new pushers are only 1mm in diameter where the pusher pin and the movement levers meet so it slips all the time and misses the lever. I would need an extension that makes the diameter a little thicker. I have been searching fo such parts everywhere but can't seem to find them. I don't have a lathe so I can't make my own. Is there anywhere I can buy a part like this or are there any other solutions?

Thanks(:

    • hi watchweasol,  I probably called it by the wrong name, I called it jumpstart but I think its just shorting I have posted my query in the safezone forum I am hoping its a simple fix, otherwise its sending to seiko to fix. thanks from England voith  
    • watch repair is all about practicing
    • what happened to the old spring? according to the website below no parts are available but they do give a mainspring listing not sizes unfortunately. Then taking that number to the home page looks like it's available cheaper than eBay. http://cgi.julesborel.com/cgi-bin/matcgi2?ref=PP_10-200 http://www.julesborel.com/s.nl/it.A/id.27029/.f because I was curious about the number I found up above I looked at bestfit online. Here's what I found out that looks like it's the right number unfortunately because it's an original spring we don't get any dimensions.  
    • After trials and tribulations, I got the balance spring working! Now I can move on to the disassembly. There's something preventing the watch from running. I suspect it was dropped and that messed up the hairspring.
    • I haven't been keeping a written log or hall of shame, but I can tell you that my early attempts to unwind mainsprings have resulted in two barrel arbors entering the ionosphere. Still MIA. I've launched but subsequently found incabloc and trior springs, a few yoke springs, and a third barrel arbor, but those first two remain elusive. (and one was from a ST36... not a small piece of metal, really)
