how to remove a V3 noob Daytona 116500 ceramic bezel and install a clean factory bezel?
Very, very slowly.
Think of a ceramic bezel as a thin piece of glazed pottery fitted to your watch. If you've ever broken a cup or a plate, then you'll have an idea of how brittle they are. Removing the bezel can be done reasonably easily using a razor blade, by working it up off the case slowly, making sure you work around the edges evenly, lifting just a very little at a time.
To replace it you need a crystal press, with a nylon die the correct diameter to allow you to apply even pressure on the new bezel.
It's not a DIY job for the faint-hearted!
