Outer part of automatic rotor fell off, can it be fixed?

Its repairable, remove the two little screws to detach the rotor from the axel its mounted on.

The two pieces were not pinned, the inner part fits in a groove of the outer part, the groove is to be closed a little for a fit tight enough to keep both pieces together.

If you don't have the tools, you might can get a local repairshop to fix it for you, you are sure to ruin it all if you try it free hand.

Some watch destroyers glue which is not a standard practice and will eventually rust.

Got it! Is there a specific tool for this job? I've got access to a huge assortment of jewelers tools, anything you'd suggest?

Personally have no tools for the task, always had to ask my late watch maker to do any repair of the sort that required shop tools.

Others will join in you thread, suggest a suitable tool and how its done.

What makes repairing this a prefered optian as opposed to replacing with a spare rotor is the makers logo lucien piccard.

Admirable looking movement, isn't.

Good luck

Yes I love the look of it! Hoping others will chime in, thanks for your help!

You might be able to peen the underside in a couple places using a prick in the staking set. Set the bottom plate so there is not a hole under the top plate (or put some stout plastic there), and then peen just the flange on the underside. NOTE: don't use the pointed alignment tool for peening!

It may require making a stake with a small enough taper to be sure it clears everything else- I don't know exactly what that underside looks like.

So, please show the underside of the inner part once you remove it, also of the outer part and underside view of the groove. thats where you will leave punch marks.

I guess he fixed it?

My apologies for such a late reply! For some reason my notifications didn't show and I didn't think anyone had made further responses. I've tried putting it in and pinching the outer groove with some jewelers pliers and it seems to be holding well, if that doesn't work I will definitely be trying what you've suggested, thanks so much!

    • nevenbekriev- You nailed it with your description of me and my reaction when the clock started ticking again. I am a newbie.  I love the sound and idea of mechanical clocks but the idea of owning one and trying to keep them running has never appealed to me. My wife bought this one and an antique German wall clock.  When I looked into having someone repair them for me, the universal response was "it's really expensive to work on them, you should just replace the movement". So, I had nothing to lose, I started researching them and opened them up. The wife is happy because she hears the sound of the clocks again. But I have gone down the "accuracy" rabbit hole. In the vertical position, the balance wheel was not floating. It was sitting on the bottom of the frame. I adjusted the lower spring collet and got it floating. It easily passed the 270 degree 3 to 5 minute oscillation test. It took 8 minutes for the wheel to completely stop moving.  I put it the unit back in the movement and checked the safety pin. It does not touch the safety roller anywhere in +/-270 degrees rotation from neutral position. But the amplitude of the rotation with the spring fully wound is weak based on what you are saying. It rotates +/-90 degrees from the neutral position.  No, I did not take the movement completely apart.  That seemed way outside my skill set at the time. There is a reason I became an electrical engineer and not a mechanical engineer. I am much more comfortable with moving electrons than tiny moving metal parts. Will I do it in the long run? Anything can happen. I don't seem to be able to let it go.
    • Isn't that the same guy who told Zelenskyy to escalate the war with Russia/Putin when they already had a peace deal? 2 years later and we have half a million young Ukranian boys dead. He doesn't seem very clever...
    • Thanks guys.  quick question. For automatic movement, particularly this one. can I power down the main spring by pushing this rachet down?  i've gotten pretty used to SW210 and powering down a manual movement. But so far i've only been waiting for the auto movement to run out of juice before opening the case.     
    • @Murks the problem you have mate is most watch cases out there to buy are for Seiko NH3X, ETA 2824 and maybe Myota 8XXX movements, oh also the big ETA 6978/9 movements which the dials start around 28.5mm. You might find one on a Google search but I suspect your main chance will be buying cheap quartz ladies watches and hopefully find one of the right size and condition that is acceptable. 😞   Tom
    • The anchor pin should be perpendicular when the anchor is sat on a flat surface and if you post a close up picture of the backplate I will be able to tell you the correct torsion spring , running fast or slow is usually wrong Torsion spring. Here is a video from my YouTube channel showing how I set the beat
