I never wore a watch in my adulthood until I was in my late 20's. i have a tattoo on my left wrist and was worried it would get worn away with a watch and got used to it being on my right. As years went on I got married and didn't like the ring and watch on the same hand, felt like too much bling, so it stayed right. I am a chef and my hands take a lot of abuse as do my watches so I finally decided to switch it back to my left to help preserve the exterior of the watch as well as the machine, heavy whisking, etc with my dominant. it's been 2 days so far and i think i can comfortable with the transition, sort of a weird feeling this transition, 12-14 years wearing a watch on my right now on the left.
