The trick is in removing the old bezel without damaging it too much. I used an old screwdriver with a bent tip that was filed into a very fine edge. You need to ease up the bezel, move the screwdriver to the side, ease up the bezel, and do this about 1000 times! The bezel can be easily bent back using a drift, again, a little at a time. Definitely not a job for impulsive or impatient people!
