·Personally, I prefer it on both sides, as do many others. When it works, it works very well, and the crystal just disappears.
Since the outer AR coating can be removed easily in a few minutes, those who don't want it can remove it if they so choose, and crystals don't have to be replaced.
How can we remove it? Does it void warranty? Do I need a dremmel drill or can I do it by hand with diamond paste? How can I safely do it on my watch?
