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

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

Back home, will check this out tomorrow. Bugs me as it took a lot of work to get this one working again...needs to fully work.

And this is the reason I stopped doing favours for people and their old watches, I had one not so long ago that I eventually spent about 6 weeks working on it, spent about £100 trying to source parts ( old cylinder movement ) and in the end only got it semi working, very frustrating and added pressure to ones life. 

But nice job done there mate, I’ll jump on the side shake train of thought and new jewel required.

Turned out the impulse jewel shellac was completely gone on the roller table. Now works, however, can't get it to run fast enough Ahhhhhhhhhh!

    • So fsr as assembly, I don't think you would find 5646 different from 5606, just that GS is 36000 beater. No unknown chalange is there as long as the escapement reamins undameged. Rgda
    • no, I have no alternatives and don't know of any. I've bought Mobius and that's all I have. 9010, 9104, 941, D5, 8000 and Moly-Kote.
    • I've just had the wood stove door seal replaced. I was hoping not to need to do that again for a few years. In the name of science I can't say I'm not tempted. I mean how dangerous can it be? Says the man who encouraged his friend the plumber to use phosphoric acid to dislodge the solidified sodium hydroxide that had blocked the bath U bend. We did take that outside first though, and yes, adding concentrated phosphoric acid to sodium hydroxide crystals and drain sludge is as bad an idea as it sounds.. so we did it several times, laughing like delinquent school boys until the explosions of brown goop stopped. The operation was a success, but sadly the patient died (or rather, melted), and we had to replace the U bend anyway.  Children, please don't try this at home.
    • I don't usually fancy the yellow crystals but it seems to work with that dial... ...and you can't set fire to it unless you share video. I speak for all of us...
    • For the last couple of evenings, I've been working on an Amida 15 Jewel based on the Amida 500 movement from sometime around 1950. This is a slightly odd mechanism, as it has the initial appearance of a jewelled lever arrangement, but is in fact a pin lever. The movement is well made, and pretty easy to work on. After a little swithering, I did change the crystal. It looked original, and I would probably have left it alone, but it had yellowed somewhat, but the thing that sealed its fate was the crazing that became evident if the light struck it from just the right direction.  As you can see, it made a marked difference to its appearance, although some might argue that the yellowing gave it a warmer look. I'm in two minds also regarding the hands. I suspect they might polish nicely, but the nagging voice in my head is saying, they might also end up looking uneven. It does run reasonably well all things considered. It doesn't quite qualify for the 404 club, as it came in at a rather too hefty price tag of £4.99 GBP. but since I've made a few other exceptions to the rules recently, it may just get an honorary membership. There are a couple of other issue I need to address. The first is the fixed pins and rather small lug width, which measures at a rather odd 15.3mm. I'll either need to source a strap, or perhaps use this an opportunity to make a custom sized strap for it.  The second issue is.. do I dare set fire to the old crystal, just to see if it is made of nitrocellulose? If you hear a loud bang and detect the smell of singed eyebrows, then you will know the answer.
