Sounds like it's worth a shot. I just have to clarify, when you say The body shop, not a car body shop but the place that sells bath and body products? Thanks for the suggestion.

: I have cleaned many plastic crystals using the
: following method, you will be amazed by the
: results!

: Before starting carefully tape round the
: crystal with masking tape to avoid damaging
: the bezel.

: To remove the scratches I use a finger nail
: buffing stick bought from the Body Shop. It
: looks like a giant nail file about 1/8"
: thick rubber and has 3 grades of very light
: abrasive surface on the surfaces. Start with
: the roughest and when scratches removed move
: on to next finest and finally the very fine
: grade.

: I then polish the crystal with "Mothers
: Mag" a polish used by custom car fans
: to polish alloy wheels to a mirror finish.
: This polish is paste and only a very small
: amount is required applied with some cotton
: wool. I have found paste far superior to a
: liquid polish which can run down the edges
: of the crystal.

: Total time around 15 minutes.

: This method just takes off enough to remove the
: scratches - if you use it on an Omega the
: engraved logo will still be there when you
: have finished.

: Remove the tape and you have a new watch - well
: a new crystal!
