Shouldn't be uncomfortable. I have a SNKN37 with the 7S26 movement and it's just a matter of shaking it a couple of times to start it.
My 4R36 monster disagrees. A month ago I shaked it to start it before going out. But then at some point it must have stopped because the movement of my hands wasn't enough (I didn't notice it)... an hour later it was running with -15 minutes. I realized it when I arrived late and saw a few clocks. When fully wound, it's around +10s a day. It's not terribly accurate.. but certainly not gaining even a second an hour.
So now, I usually wind it before I wear it. The winding isn't as good as on a manual but at least it never stops midway.
