How to fix the noisy winding construction at a PAM389 (A7750 movement) tutorial

[PaBrBe]

Great tips, thanks!

What kind of oil is recommended for oiling the rotor?

 

[aflop]

Möbius 9015

 

[chris3007]

Or moebius 9010

You're absolutely right! I'm not sure if there's such a thing as 9015!

Sticky this thread is a must i think... Not sure if this will work for AP's 7750, asking a watchsmith to test..

 

[chris3007]

It will work for every A7750 but it's much harder to do with a AP A7750. Because the bearing at a AP rotor is fixed with a clip and this clip can be pain in the arse. Also setting the bridge with a working chrono is much harder.

Alright, Moebius 9010!

Where do you buy that kind of oil, internet, watch repair store or what (I live in Sweden)?

And while I'm at it, I need silicon grease for the gaskets, too, right?

 

[chris3007]

You can find the oil and the grease at eBay. But eBay is the most expensive place for watch parts.

Hey mate, any idea where I can get a couple of the stop clicks 52.053.00 ?
I've searched the net and can't find any.
I've got a 389 and a 382 that are in desperate need

I found them here but you need to order over $100 worth of stuff

Thx Mate, you think it would be better to replace the rep rotor with a oem eta?

 

[chris3007]

You must glue or press the new bearing to the PAM rotor. So it's better to change the whole rotor. And with a closed case back is it no problem. I would change the bearing just with a open case back.

Ok so does cousins uk have a complete rotor/bearing part as a set?

 

[PAMaholic]

I found this one: http://www.uhren-roemer.de/Uhreners...tor-fuer-Valjoux-ETA-7750-runder-Schliff.html is it the correct one?

 

[chris3007]

It's the correct one.
