In this video I make a restoration of a vintage watch from 1946 (post WW2) with Radioactive glow on the hands that's been abandoned for many years. It's a Certina Labora vintage watch, all of the restoration is done by hand manually. It's a mechanical watch with a caliber KF 320. ASMR sound.

As this is a watch from 1946 it can be radioactive radium on the hands and dial, I always use protective mask and gloves when handling it.
This vintage Certina watch was very dirty and oily when I opened it. So the cleaning had to be done piece by piece very thoroughly. Every cog tooth needed to be cleaned with wood sticks/peg wood. The balance staff was totally worn out and had to be changed.
After the restoration the Certina watch works quite fine. It runs a couple of seconds +/- per day which is stated by the timegrapher and the amplitude is around 270 degrees which is good. All my hammering paid off and aligned the arbor and the center wheel. I also hammered the barrel and the barrel cap which is not shown in the video.
In this video:
-Disassembly of the watch and check for problems along the way
-Inspection of all parts if they are worn or broken via the microscope
-Manual cleaning, I do this with Rodico (Bergeon), some toothpicks, pegwood. Then let all parts be in benzine and later a double bath of IPA (Isopropyl alcohol) which wasn’t shown in the video. The pallet fork gets a bensin bath and the Epilame treatment, balance wheel will only be cleaned with benzine.
-Polish the acrylic glas and the casing
-Reducing the barrel arbor hole size, barrel hole, barrel cap hole, center wheel hole with the staking tool
-Assembly and oiling all relevant parts
-Checking if the movement works fine and then checking it with the timegrapher
