  1. Well I got a Radex RD1212-BT Outdoor edition - obviously so I can take it off roading in a hurricane. Actually it was nominally more expensive than the base model but offered with next day Amazon Prime delivery. Fired it up and tested it on my suspect dial...nothing. Nothing at all. Well, it did indicate 0.10 background radiation. I suppose that's good but part of me was hoping it would indicate Radium just so I could see it work. But this poses a question for me - this particular device only detects Beta, Gamma, and X-Ray. NOT Alpha. I'm no nuclear scientist so here comes my dumb question: do I need a geiger counter that detects Alpha particles to determine if I have a Radium dial?
  2. Long silence but I’ve finally gone and picked up a couple of jewels and replaced both brass bushings with the appropriately sized jewels. I may have a little bit of end shake adjustments to make but this has certainly helped the situation. Tweaking and testing now - hopefully this will solve the issue for good. Thanks for all of the help and advice! You’ve helped me level up my watch making skill set. Oh, with the added jewels, should I scratch out the “17-jewels” engraving and scratch in “19”?
  3. Thank you! That's what I'll order and give a try.
  4. I have a UG218.2 with WAY too much sideshake in the main barrel. I have all ready replaced the arbor and will be moving on to dealing with the bushings. I'd like to try my hand at replacing the bushings with jewels. I'm going this route because 1. watch supply stores don't seem to sell the bushing and 2. I don't have a lathe. I'm basically at the point that I can try this because the next option is replacing the main plate and barrel bridge. So if I mess up the jewel replacement, I'm where I would be anyways. I measured the arbor: Top Pinion is 0.70mm Bottom Pinion is 0.80mm The bushings are still installed but measuring them on the main plate and barrel bridge comes up with: Barrel Bridge Bushing: ID: 0.80mm OD: 1.20mm Main Plate Bushing: ID 0.90mm OD 1.80mm It looks like I can get Seitz Center Jewels 30714 in sizes that will fit these measurements. Question is, how much space should I have for the arbor? For example, if the measurement is 0.70mm, do I get 76, 78, 80? Please let me know if you have any recommendations on this. TIA!

  6. What did you do to resolve it? We’re you able to remove the bushing and replace? If so, did you use a jewel, brass, or bronze?
  7. So I cleaned and re-oiled the mainspring and barrel. This time using 8217 braking grease on the walls and 8141 on the spring itself. I then worked the spring to latch securely onto the arbor - just in case something was slipping there. And it happened again! But I got to observing things as I wound I witnessed the slip. The whole barrel whizzed around without effecting the ratchet wheel or stem. What I’ve discovered is the barrel has quite a bit of wobble when installed. So much that it can wobbles off the teeth of the drive train. Which explains why it releases on an autowinder but was not releasing when wound and set perfectly still. So now I’m on to suspecting either the arbor is worn or the brass jewel is worn (or both). I can readily order a new arbor from Ofrei so I’ll start there.
  8. Aha! Thank you! 8217 en route to me. That's what I get for listening to advice on an online forum without confirming if the person providing the advice is legit...
  9. I have Moebius 8200 on hand. That's what I have been using on barrel walls to date. So far no issues. But that isn't to say I'm using the wrong stuff. I'll order some Kluber P125 if you think that's a better one to use.
  10. Update: I went to wind the watch this morning - the mainspring unwound after 18 turns of the crown. When it unwound, it zipped free without effecting the crown. This leads me to think either the double ratchet is not catching properly or the arbor is slipping.
  11. The issue is no the bridle slipping inside the main barrel. The issue is the mainspring unwinds after 4 hours(ish) - like what would happen if you release a click without holding on to the winding stem - ziiiiip! Now I have not observed if the winding stem spins or not. Because it happens at approximately 4 hours +/- 30 min I haven't set myself up to observe the watch for an hour, four hours after winding. Obviously this would indicate if the click is releasing. I did not have a chance to get into it last night but I will look into the double ratchet wheel - perhaps try cleaning it again and relubricating. I treated it similarly to a reversing wheel with a small amount of 9010. Perhaps I should compare it closer to a Rolex reversing wheel and lubricate like that?
  12. That's a great idea to investigate - the double-decker ratchet wheel. It has a slipping mechanism internal to it that allows the hand-winding to work independent of the autowind. I did not pull it apart to inspect the inner workings. I wonder if it is slipping and releasing the mainspring! Sorry about my original description, I was trying to describe my process of elimination. I started with a full movement reassembly and testing. Upon giving it a full, hand-wind (50 turns) I placed it in an autowinder to see if it would continue to go perpetually powered by the autowind mechanism. In this case, the mainspring unwound after approximately 4 hours. Because the oscillating weight had a bit of wobble (due to a worn axle I suspect) I thought perhaps this was causing a problem. I removed the oscillating weight, gave it a full, hand-wind (50 turns) and placed in autowinder. Same mainspring release after 4 hours. Replaced mainspring - same results. I'm trying to determine what would cause a mainspring to release after approximately 4 hours of working fine. For what it's worth I audibly hear the main spring release when it happens. I have had one instance of reassembling completely after installing the new mainspring that I fully wound it and left it sitting dial up. That was the one and only time it was held it's power reserve for 32 hrs.
  13. Hi, Right now I’m working on a Universal Geneve Polerouter with a cal. 218.2 micro rotor movement in it. It’s been cleaned and relubricated. Micro rotor is a little loose and could really use a new axle. But I want to see if I can get it going leaving that aside for now. They’re expensive and I can be patient on the replacement. I changed the mainspring as well. Put in a Best Fit WA89. Seemed it fit fine. Movement regulated nicely and showed good numbers. upon putting it all back together and popping it in a autowinder to confirm it’s doing okay. After about 4 hrs the mainspring unwound suddenly. Okay. So I tried tweaking the connection to the arbor - broke the spring. That’s okay because I stumbled upon a UG mainspring from Ofrei. New spring in. Good fit, good everything. Reassembled and test dial up on my desk. Power reserve holds for 32 hrs. Time to try the autowinder. Same issue. After 4 hrs or so, mainspring unwinds. My next guess is the wobbly micro rotor is causing the issue. It’s weakly engaging the click and letting the mainspring unwind. I pull out the micro rotor. Try again. Same result. My last guess is to replace the barrel arbor. Any thoughts or advice on this riddle? TIA!!
