Mystery (self-healing RA clock!)

Recommended Posts

What could be a possible explanation for this?
1)This clock, previously working, began to only swing for a few seconds after I started the pendulum. Tried several times.
2) I left it alone for years.
3) then I shipped it across country in a moving van, laying on its back in a cushioned box.
4) I left it in that box for years, on its back.
5)I took it out finally and noticed a small amount of oil had leaked out (that may not be relevant.) I started the pendulum (and days later noticed that it was stored in an almost wound-down state). Without any further intervention, from the first pendulum swing, it has now been working beautifully for 1.5 years!
Anyone have any guess as to how to explain this?

    • @Jon The link is no longer working and I wanted to see that demonstration again. Is there any chance you can make it available again? I'd appreciate it!
    • Or, if you have a staking set or jewelling too, just use one of the stumps. You can choose a fine tip to fit inside a jewel if necessary.
    • Good morning,   To be honest, I'm not sure I trust my own logic anymore 😅. But here's a picture of my own (failed!) attempt to install a new rotor axle. I punched way to hard and even split the metal of the rotor. My thinking was that, in my case, the axle sits "deeper" in the rotor and hence the rotor would be closer to the movement plates. Vice versa, I was thinking that a very light punch could cause the rotor to sit rather high. But not sure that makes sense because in both cases, the flat part of the axle and the rotor align equally.     Sorry, but is he saying that the outside of the caseback has been polished to such an extent that the inside of the caseback has deformed/sunk??? That sounds crazy to me because those casebacks are thick! Can you see any signs of that on the inside of the caseback? Have you tried screwing in the caseback a litte bit more or less so that the supposedly "sunk" part of the caseback would move from 9 o'clock to e.g. 6/7 or 11/12 o'clock?  If the caseback is truly deformed, maybe it could be punched/pressed back into shape (e.g. with glass/caseback closing press).      I agree with your choice. But yea, Rolex makes it VERY hard for independent watchmakers to do a perfect job because we can't get (original) parts easily.      Your pictures aren't too bad. But still impossible to see if the rotor isn't perfectly flat. You'd have to look at it with your loupe, from the side (like the pictures), and turn the rotor to see if the gaps (with the automatic bridge plates) increase/decrease.     Finally... how is the up/down play of the rotor? To test, take a toothpick/pegwood and press on the small triangular side of the rotor next to the axle (NOT the big side where the weight is. But the opposite side.). Does that lift up the weight-side of the rotor? There can be some play, but it should really be minimal. If there's too much play, a new spring clip is the first thing to do. After that, one could play around with the jewels. This is too much:
    • could start a new sub-brand: Bergeon-Pro Worked for Apple phones! Ah they already beat me to it:  
    • Hello, those RR pocket watches are nice watches, there are still parts around...
