(I get no money if you click that btw -- it's just for reference)
The watch has some "trading features" even. If I see an interesting trade I can let it take the trade and finish it to "take profit", while I go and do something else. It has a touch UI and a 240x240 16bit colour screen -- so lots of possibilities there.
May I ask why you're doing that on a ESP? Very cool...just surprised at the choice.
