I charge my iPhone daily and it doesn't bother me at all.
I charge my iPhone throughout the day, whenever I have access to a charging cable, so my phone is fully charged and ready to go at a moments notice. But I also don't have to do anything special to charge it. I have docks at work, home, and in the car which makes just throwing it into a cradle a mindless process. When I need it, I just grab it and go.
The watch is different -- you'll have to take it off your wrist and pick up a proprietary cable and connect it. I'll need at least four proprietary cables to charge it in the same places as my iPhone, which means more cables. And then you have to put it back on your wrist, and buckle it when you're ready to go. It will be a bit more of a hassle than just throwing an iPhone onto a charger.
