Help with Lower Jewel fitting

Recommended Posts

I am working on a Illinois 12S Aristocrat pocket watch and the previous maintainer simply dropped a jewel in the pocket for the lower balance jewel; resting on the jewel end cap. I think the plate requires a friction fit jewel setting with the cap jewel, so I found a setting that sort of fits with a jewel that is the right hole size. So should I just go ahead and press in this setting? Anyone experience this situation before. I did not think that there were pressed in lower Balance jewel settings. My watch is the third model.42a7dd060f322825cf6b91a6eabaf79a.jpg1f951b80270f81354efc0fb96c6c5a40.jpg76fb62ec64573dee995f53fe2e8741d5.jpge6926e4dbbe89fa3d5a7b63ee85463cd.jpgNot presses in yet.3ea2007563cc7a4016aa69c983c1e9c7.jpg

the lower  jewel in some vintages elgin pocket watch balance staffs  have caused a problem for me.   one experence;   bought a watch that appeared to have a broken balance staff,  on dissassembly,  the staff was in tact with the lower jewel pushed out.   this could have hapened when the former owner pushed the jewel down when fitting the balance cock.?  vin

Was it friction fit in place? This one appears to be a friction fit, even from the data I included.

Anytime were working with American pocket watches it's nice to have the serial number especially when looking for parts. Then because this is not your normal 12 size it's extra thin looks like you're right it's a friction jewel setting.  So image extracted from a listing so we get the diameter and the thickness. Then the other minor problem with Illinois all the different part numbers to make for a confusing mess.

Thanks for the data. Friction fit is odd.

    • Thanks everyone, food for thought and I’ve learned some by reading your posts. More research needed! Sent from my iPhone using Tapatalk
    • The Spiedel wasn't really doing it for me, so I popped it on a plain leather band, somewhere between rosewood and burgundy.  Much more appropriate I think, and a sight more comfortable I might add. I was almost tempted to post it in "Watch of Today" again, since I'm still wearing it. Not a single issue so far, and hovering somewhere less than +20s/day aver the last couple of days. 
    • I figured it out. I totally overlooked that this particular 974 has the little blue locking screw to lock it in the winding position when out of the case which explains why the hands wouldn't move. I didn't have it locked which kept it in the setting position when out of the case and thus not having enough power to turn the hands....I'm an idiot
    • I think this is possible if there is very low friction to the cannon pinion. The balance and the trainwheels run but the cannon pinion and all following wheels and the hands do not as one of these parts is stuck somehow.    I would try and analyze step by step. Take of dial, hands, hour wheel and intermediate wheel, put the minute hand on the cannon pinion and observe. If the minute hand does not stop at 12.05 take the next step and add the intermediate wheel and observe. After that add the hour wheel and so on until you find the step where the error occurs.  
    • The watch never stops, just the minute and hour hands at 12:05 (seconds hand still tics). I've replaced the hour wheel as well and the cannon pinion isn't rubbing. I can't understand why they would move for 5 minutes and then stop every time even though it still runs. If something was binding I would think it would stop the whole watch?
