Restoration of an antique pre-WW2 pocket watch - 100 year old Cyma 777 - german empire silver case

This time I´m restoring a Cyma pocket watch. It´s from the pre-world-war 2 period and about 100 years old.
It´s powered by the Cyma 777 caliber a hand-wind movement with 15 rubis and it beats at 18000 bph.

That pocket watch is in a bad condition: The silver-case has tarnished over decades, the glass is broken and the movement isn´t running at all. There is some corrosion on the dial and the hands are dirty and bent.
Unfortunately watches from that age doesn´t have a shock-protection so the balance staff is broken. It was hard to find a new replacement-balance but I was lucky.

I´m cleaning the case by an electrochemical reaction with aluminium and soda-water and polish it afterwards. The glass will be replaced (or maybe I just turned back the time by 100 years?)

After everything is cleaned and polished, I can re-assemble the movement with some fresh oil. After some fine-tuning, this watch is in a fantastic beat (+4 seconds per day) again.

I´ve added some (super-)slow-motion and macro-scenes - let me know in the comments what you think about it.

I hope you liked this restoration, if so, like, comment and subscribe ;)
