Few comments on the video...
1 - No need to put the crown in the "notch" in the remover - the crown is well under the remover unless you have somehow gripped the bezel all wrong.
2 - I would suggest removing the bracelet - the bezel comes off easily when everything is clean, but if it's packed with dirt it can be difficult to remove the bezel and there's a tendency to crank on the bracelet, and you can damage it.
3 - I install the insert with the steel part of the bezel already on the case - that way you can get it exactly spot on.
4 - Big one - the tabs on the click spring need to be lubricated with some grease - I use Fomblin UT-18, which is the same grease used for nitrile case back seals, crowns, etc.
