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

[Max50916]

Hello! The outer part of the rotor on my grandpa's lucien piccard seashark (AS 1580 movement) has come loose. Is there any way to repair this rotor or must it simply be replaced?

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!

Many knowlegable and hands on memebers can help only if they knew of your thread ,  like @praezis or @nickelsilver .

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!
