sing fine glass beads the finish is awesome! used especially when case backs.
after sanding cut buff and other steps fail to remove deepscratches -plus it
will remain great looking and handle any further scratching very well

IMG_0371.jpg (134670 bytes)

IMG_0379.jpg (158743 bytes)

this case back had no info, when they do, the bead blasting does not remove it. I
always make the decision based on several factors. note new black rubber seal with:

mixing luminova – I use my own lacquer mix with AF Luminova
phosphorus is the primary ingredient.

IMG_0384.jpg (136533 bytes)

the crystal is original. of course it did not look like this! using alcohol and other
chemicals i actually “destroy” the ORIGINAL crystal removing the yellowing effect of
aged crystals and then coat them before i spend an hour polishing them. this
crystal will be able to be buffed at least 5 times! only serious deep scratches may
prohibit buffing/polishing. and that means deep near cracks! so better than new!!

IMG_0382.jpg (102767 bytes)

ONLY THE BEST FOR MY PATRONS!:
HAND MADE IN ITALY GENUINE LIZARD WITH TOP GRADE LIZARD
AND SIGNED AS SUCH!
