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.
