Case issues !!


Question

Having been in the business for many years I have recently come across a couple of watches that have had issues I’ve not seen before. Out of the case the watches work perfectly with great amplitude and timekeeping. Once inside the case and the case clamps are tightened, the timekeeping is terrible and both watches I’ve serviced stop !! I’ve tried tightening the case screws in various orders and tried the stem in several combinations but to no avail. The only conclusion I’ve come to is distortion of the case.

Loosening of the case screws solves the issue but loose screws are not good!! Any ideas??

the old Omega did the same thing.   mvt. screws were special springs.  new spring tabs solved it.  if the  mvt. is of the tight type,  perhaps a washer is missing.  i am eager to hear the  solution.  vin

The honor goes to other watches too, not just Omega.  I have a Peseux that dose the same. My late watchmaker showed one that had no screws to tighten, stopped without hands and crystal or stem installed. 

Sorry Peter don't mean to sound discouraging or disagree, most common cause is the dial plate though.

    • Chances are the hairspring is touching somewhere. Othe possibilities are insufficient end play, try loosening cock screw, or severely bent balance pivots, inspect visually.
    • hey guys i need the nut (see pic 3) to go inside the hole (see pic 1 and 2) but as you can see if i try and drill it to size the bearings just rotate. I have tried putting a needle inbetween the bearings but that don't stop[ it spinning with the drill either. really just looking for some suggestions on how i can widen the hole without it spinning. cheers gary
    • There is absolutely no reason to install the balance without the pallet fork being fitted first unless you did some work on the balance (staff replacement, hairspring adjustment, pivot straightening / polishing, jewel replacement, etc). A few questions for you: - you did not by any chance lubricate Pallet Fork Pivots / Jewels? If you did, remove the Pallet Fork, clean it, remove any remaining oil from Top and Bottom Jewels, reinstall the Pallet Fork. That should resolve your "stopping" issue. - also, do not forget to very-very-very lightly oil contact surfaces of both Pallets with light oil. Not even a drop - just a touch with red oil pin. Good luck
    • Ok I didn't make a 3D model or anything, but laid out the most important part, the plate. The back piece is 40mm x40mm, the arm can be anything hinged any way just so that it comes down over the balance rim. The support piece for the inside of the rim can also be anything, on the old tools they were V shaped and pressed into a hole, on my friends it's a simple pin that has a notch filed in it. The notch/V permits whatever bit of screw that is sticking out inside the rim to be unharmed when working on it. The threaded holes for the pins are a 2mm thread, but anything near that would be fine.    You can see in the pics that there were different ways to hinge the arm, either with a hole drilled all the way through the 40mm back plate and the arm recessed in, or with pressed in hinges, both would have been a test of the student's patience, not becuase they are necessary. A simple hinge from a hobby store for dollhouse work or whatever is fine.   I don't know what the pin sticking out the front of the tool is for. They all have it, but?
