Here is my experience.. sorry, I cannot get video due to busy work traffic...
All I want to say is that is so easy and I was afraid of making mistake and mess up everything but I understand that it is all about to know the paint features..
First I don't want to paint the bezel because I thought this paint is too sticky and there will be some bad paint tinges on it. But after my first try on different glass, then I realised that it is such a paint that dry with these steps;
first 15 sec : it is still liquid
30 sec : such a elastical
1-2 min : a little bit dry but easily removed by toothpick
I use decoart paint glass pen. Its nib is so sensitive. I first covered the bezel with tape and start painting the glass edges. It was very hard to move the pen because the nib is just stuck at tape intersection points. and its structure has deformed. But I paint anyway. then I pull all tapes out after paint but the paint at the glass edge came with tape strips.
Then I clear the watch again and I just paint the edges covering nowhere. after 1 min. I removed the paints on the bezel by toothpick (so easy). it is important to make one single movement from begining to end.. if you interrupt painting, then you will probably have a little bit darker point there. slow and continiously paint at once. here is the result..
