Watch Makes Scrapping Sound Crown Up

Recommended Posts

I just finished repairing an old 7J Waltham for a friend. Got it going well face up, face down, crown down: but scraping sound and slows down and sometimes stops crown up. Is this the impulse jewel closed to the opening back of the palate fork or could it be the hair spring. This is a very cheap watch so I don’t want to spend to much more time. Already replaced the mainspring and cleaned it up significantly. And I made a bow out of a coat hanger wire and a lot of pounding.67234001858654b499674c8b1808ad55.jpga54ecfef068a30020dbca5707249527c.jpg71d3d62d4931fd54018ff89c74712060.jpg3390c897d7ca9e21336ddfcdbbfda278.jpg

Do you get the sound only when cased or is it ok  out of the case.

Not sure, will need to remove it from the case. The balance looks good and it runs really well in all positions except pennant/crown up

I too, suspect the roller and guard pin rubing, since excess side shake reduces the distance between the two in dial up position. 
 
 
 

I think you may be correct.

    • Some updates, I measured the  mainspring barrel of a 6498 and it's 16mm. I also tried loading a 10mm mainspring on an undersized winder, it did not load fully. So I answered my own question hehe. thanks.
    • Thanks. A small correction to my earlier post,  it is a Poljot 2614.2H, not a Vostok. http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&&2uswk&Poljot_2614_2H
    • I've been thinking about getting a Russian watch myself. Nice piece Andy.
    • This is the progress so far. The first image is the ebay seller's pic and the description was "Does not start, maybe battery but unable to confirm". In reality, it wouldn't wind, wouldn't set and the scratched up crystal looked even worse in real life (and the second hand had fallen off in the post), but I figured it had to be the twin of the one I already had, and therefore was well worth the 0.99p I bid.
    • Thanks for the correction regarding the movement. You are spot on  with the fiddly calendar works, the first one I looked at, I launched those two springs more times than I care to mention, however forewarned is forearmed, so this one came as no surprise, and I even remembered which way round everything went without having to dig out my pictures of the first teardown.  If you are aware of the issues and take care to do things very gently, the calendar works go back together reasonably easily. I did mange to gocha myself with the keyless works by pulling the crown out with the stem in the wrong position, but I knew I had been an idiot the moment I did it, so I only managed to indulge in that one screwup. The watch is running well, but I haven't attempted to adjust it yet. Beat error is around .1 to .3ms and it kept up a good pace, within 20 seconds or so over the course of the day even without me tinkering with it. I'll let the lubrication settle and do a bit more with it tomorrow. The amplitude is still a little low at around 240 fully wound, so there is scope for a little improvement in that too. The other one runs around 270, so there is no reason to think this wont. I have an almost complete spare movement, including a mainspring, etc.so if I need parts I have them.   That red and gold Poljot on your "About me" page is a cracker, as are the others in your collection.
