Restoration The TANK of Watches - Polishing - Vintage Certina DS-2 - ASMR - Cal 25-661

In this video I make a restoration of a watch that is The TANK of watches. This vintage watch was produced in ~1970 by Certina and its model name is DS2 (Double Security), the meaning of this is that the watch can be dropped, it can take hits etc, like a true TANK! It’s a manual watch (you wind it via the crown). The movement is called cal 25-661. This video is only ASMR. This watch seems to be the most robust watch that has ever been built. It has a big rubber shock absorber inside of it that separates the movement from the casing so no shocks will travel through the casing to the movement. After the restoration the Certina watch works well. It runs around a couple of seconds per day /- which is stated by the timegrapher and the amplitude is around 290 degrees.
