Plastic watch crystals scratch very easily with the result that they soon look unattractive. Replacement of the crystal is not normally possible, especially where watches have plastic cases.
Watch owners the world over suffer from this sort of problem, but now PolyWatch, a new type of special-purpose polishing paste, offers them an extraordinarily simple solution. For the first time, consumers can remove scratches rapidly and cheaply from their plastic watch crystal by carrying out an easy-to-follow "do-it-yourself" procedure.
Apply PolyWatch to the watch crystal. Polish the scratched areas for 2-3 minutes with great pressure at a right angle to the scratches, using a piece of cotton wool. Deep scratches need to be treated more than once. Finally, remove any remaining PolyWatch with a cloth. The tube contents of 5ml is sufficient for approximately 10-12 applications.
The plastic crystal is very slightly dissolved and ground down by tiny abrasive particles. The edges of the scratch marks are then smoothed off and the cracks filled in with some of the original plastic from the watch crystal.
Most of the people buying PolyWatch will be those owning fashion watches with watch crystals made of plastic, especially owners of Swatch and Fossil watches.
