I'm just curious, is it a big job to remove a sapphire crystal from a Rolex Oyster Perpetual?
Is there a high risk of damaging the bezel?
What about reinstalling a sapphire crystal, is that difficult?

Just interested because I don't really know how this works

The job itself is quite simple provided you have the correct tool for removing the bezel. If you don't, then you can easily bend it and leave it unable to be put back on.

Once the bezel is off, the glass is held in place by the gasket around the rim, which lifts off easily. It is not pressed into the case as with many other brands.

Care to give us a "How-To"? :)

Thanks for that information.
Yes as I expected, one must have the correct tools.
It is interesting how the sapphire crystal is held on by a gasket. One would have hardly thought that would have been sufficient to hold the crystal in place.

The gasket only holds the crystal in place. The pressure comes from when the bezel is pressed on. The friction on the bezel on the gasket is what seals it.

I might get round to a 'How to' someday.
