Patek Philippe

Hi all, I thought some of you guys and gals might find this very interesting. It gave me some ideas for restoration of vintage watches. https://watchesbysjx.com/2019/08/patek-philippe-pendant-watch-restoration.html

Thanks for sharing Graziano.

 

Question:

Aren't escape teeth polished?     He didn't on this one.   Bumpy rid for pallets running on teeth! 

How is it accomplished on mass produced escapes in industry?

Not that I plan to make any, just curious.

I agree, that escape wheel could have been more "Patek-y". Normally a Patek escape wheel from that time would have been thinned in the center, on both sides, leaving raised teeth. The center would have a very uniform matte finish, and the sides of the teeth would be black polished. The teeth would have also been beveled on the impulse surface with a very fine finish. I'm a bit surprised as Korpela normally is a maniac for doing things 110%.

Hi Nucejoe, as far as I know mass produced escape wheel teeth are polished with compound loaded disks of wood on a machine.That one looks like it was cut from a coke can. Surely it was finished off before final assembly. One would think that it would go without saying in the watchmaking industry that the escapement must highly polished and hardened to specification for reliability, accuracy, longevity. Anyway I reckon that was an interesting story

Sure eats amplitude,. Lots of friction.

Yes the extent a watch maker would go to for his love of fine crafts, interesting. 

Thank you for sharing.

In addition to some serious skills on display, there are some truly awesome tools shown in that post.

I'm sooo jealous.
