Wow, I'm the same and never knew it had a name. I write left-handed use use a fork with my left-hand and generally consider myself left-handed. But, I throw right-handed and swing right-handed (although I became a decent switch hitter in little league, I had more power left-handed but more accuracy right-handed). Some tasks I have trouble picking a hand and go back and forth between the two. When I bowl (which is usually only about every 5 years or so) I spend the entire time switching between both hands to find one that feels more comfortable. I also pass a tennis racket from hand to hand depending on which side the ball is on, but I play ping-pong solely with my left hand. When I first started using computers in elementary school I made a conscious effort to use the mouse with my right hand because even then I knew that every computer I came to would have the mouse on the right side. However, I usually use a laptop trackpad with my left hand. I, like you, found wrist watches uncomfortable to use. I wore one in high school and always put it on my left wrist but I had to remove it every time I sat down to write or type. I think smart watches could have some useful applications, especially when cycling as a glance-able cycle-computer paired with a ride tracking app, but I just don't think I could put up with the pain of wearing a watch every day to get any benefit from one.
