It is thought lately (at least by many) that with the escape wheel and pallet fork that only the stones and wheel teeth should be treated. This due to complications otherwise.

Why then when doing the reversers is the whole part including pivots treated. While the escape and pallet move quickly and the reversers slowly, I would have thought that the extra forces involved would have made the pivots also wanting no treatment.

The force involved in the motion of the escapement is orders of magnitude smaller than the force involved in the automatic module.

If there was a build up of residue or impurities in and around the pallet pivots or the notch of the fork it would have a noticeable affect on the amplitude and ultimately the running of the watch.

It is not really as big of a concern for the escape wheel pivots although good practice is still to not to epilame them. There is no concern at all with the reverser pivots because the rotor provides enough momentum to keep things moving even after the oil has long since dried out

Thanks much.

According to Rolex specifications there is no issue coating the escape wheel pivots. If there was an issue, then the center seconds wheel shouldn’t be coated either. Or the 4130 clutch wheel. It is my understanding that it has to do with lubrication. If you epilame the pallet pivots then you are applying a coating. If that then runs dry, that coating has no option but to come away.

I'm lazy and I've always dunked the whole pallet fork and escape wheel in there. Never had an issue.

Just doing the pallets is only easy to do if you use the white Rolex 'box thingy' which is supplied with RL-0 epilame, but I refuse to use that thing, it's awful.

Rolex box vs the hour glass type, you will extend the lifetime of epilame a bit more with the latter.
And it is a lot easier in use IMO.

I certainly missed something else. There are a lot more parts ready to be epilamed than I ever heard about. What is the complete list of 3035 parts that are now to be processed?

Reversers, escape wheel, seconds wheel, pallet fork. And ever since I learned about the 32×× having the keyless in epilame as well I swear by it.

I even know of watchmakers that epilame the barrel arbor too.

I actually think that when you take a new Rolex barrel, the arbor is coated with epilame from the factory. You can really see it 'stick' to it when you lubricate it.

I know of watchmakers who epilame the barrel and cap as well.

I believe Panerai basically epilame most of their movement now.
