Removing Red Dot Chronograph Bezel

Aloha from Hawai'i
I need to remove the bezel on my Zodiac Valjoux 7750 Chronograph, Red Point model.
Instructions on how to safely remove the bezel will be greatly appreciated.

While some bezels can be removed with a blade, the safest way to remove/reinstall many of the rotating bezels is with the Bergeon 7152 tool.
