In this video I make a restoration of a Vintage Longines Swiss Mechanical watch, all done by hand, ASMR and no talking. It's a mechanical watch and it's from the beginning of 1970 with a caliber 428 movement. This watch seems to have been left alone with a missing jewel part and it seems there is no oil in it! Maybe a watchmaker had its reasons to just leave it.
In this restoration I do manual polishing and cleaning of the watch, everything is manually done by hand. This watch movement has 17 jewels and it has shock protection. It’s a manual hand wind movement (you wind it via the crown to give it power).
Longines is a well known company that is a Swiss luxury watchmaker based in Saint-Imier, Switzerland. Its winged hourglass logo, which was registered in 1889, is the oldest unchanged yet still active registered trademark [en.wikipedia.o...].
This vintage Longines watch was very clean when I opened it but it didn't have any oil in it. And one major problem was that the whole chanton with its cap jewel was gone under the balance wheel. This resulted in a very erratic ticking.
After the restoration the Longines watch works fine, It's about +7 seconds to fast over a day which is stated by the timegrapher. When tested in different positions this could vary a bit but it was always around +/- 10 seconds per day. I think that's very good for a 50 year old watch.

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 bensin and later a double bath of IPA (Isopropyl alcohol). After the IPA batch I blow all parts with air until they are totally dry. The pallet fork gets a bensin bath the Epilame treatment, balance wheel will only be cleaned with bensin.
-Watch casing manual polishing with 2000 grit paper so you don't cut any angles of the steel of the watch. Then cloth polishing to just lay down those high spikes in the metall so the surface will be more shiny.
-Sanding the watch glas and then polishing with Polywatch
-Reducing the barrel arbor hole size with the staking tool
-Assembly and oiling all relevant parts
-Checking if the movement works fine and then checking it with the timegrapher
