IMHO, putting PPF for a watch is totally different than PPF on a car.
This product reminds me of what my mother who came from a different generation used to do with her furniture and how she covered the living room sofa and chairs in clear plastic covers because she wanted to protect the fabric from stains, wear and tear, etc.
My butt used to stick to the covers in the summer time and the plastic didn't move like the material underneath so they cushions were extremely uncomfortable to sit on.
I would never do this to my furniture today, I like the feel of the fabric against my body and if there is a stain you could always get the fabric professionally cleaned.
I proudly wear my watches and if they show some wear it is a badge of honor!
