This 3M material truly works wonders to protect a bracelet. The images suggest that it is quite noticable when in fact I assure you that unless you know it's there, or are looking very carefully at the bracelet, nobody can tell.
It can be obtained thru Ebay etc. I use it to protect areas of my car, jetskis, etc. then realized it is perfect to prevent damage to a watch bracelet! Remenber the key is to not overextend it and try to fit it exactly. It will only peel off in a week. If you cut it so the edges are rounded and the material is not near an edge, it will protect for months. Be sure to use isopropyl yo take off any grease before applying and SAFE THE TEMPLATE! This way you can cut another in 30 seconds and reapply.
I love the feeling of knowing I have the 3M protecting the clasp whenever I am at my desk, never need to worry about scratches!!
