Watchmaking, Restoration of movement M. Großmann 3955

Nice work! Your movement was rusty but it looks like someone put rust converter (phosphoric acid) on it. All the polished steel work turns grey although it can be re-polished unless it is pitted by the rust. You can see the acid also affected the silvering on the plates.

It seems like you mentioned, but who would do such a crazy act?

@spahlow There are many crazy people out there, especially when it comes to repairing watches!

Years ago I was taught in making frosted silvering.

I guess it was wetness. The brass subsurface was not correctly prepared.

In addition somebody worked on it and tried an overhaul.

A story we cannot find out.

A little dry diamond powder for each leave or for all leaves?

@loricastro

Like you need, also you have to take more than one toothpick.

Cheers Steffen

Yes, I used a toothpick, at the top I added little diamond powder 0-2, dry and only a little. After a while I repeated adding powder aso. The result was very satisfactory.

Mr. Spahlow, at 3:59, it seems to me that you are using a toothpick to polishing the leaves of the pinion. Is this correct? Are you using some kind of polishing paste or powder in the toothpick?
