It’s my opinion watch in the video has been deliberately covered in mud and colouring that looks like rust staining. If the watch had rusted as much as it appears to be, the steel pivots and pinions would be beyond redemption.
Here are a couple of photos I took of the destroyed parts of an Omega Seamaster I was asked to fix. Virtually everything had to be replaced because of corrosion due to the ingress of water after my friend had a shower having forgotten to screw down the crown.
