I would be this “someone”…
And yes, I noticed that most people wear it on the left wrist.
Since this is GQ, I feel compelled to post the factual answer to this question:
NO.
Ambidexterous here, and i wear mine on the right. I learned to do this working in a machine shop - disassembling cylinder valves my left hand was more active near hard obbjects that would damage the crystal, so I wore it on the right. Never got into the habit of changing it back after a while, so I still wear it on the right. i also tend to drink coffee with my left hand as the mousepad is to the right of my keyboard.
I’m an ambi, and wear it on the right. It dosen’t feel ‘right’ on the left for some reason. Gee, is there an echo in here? 
Count me in as another lefty relic who grew up wearing his watch on the left hand because it was easier to wind it that way, consarn it.
I don’t know why I started wearing my watch on the right hand. Maybe because I’m lefty, and was “supposed” to wear it on my right. Winding was never a concern – I grew up on digital watches – but have been pure analogue since high school, thank God – even so, winding’s never a concern. Batteries and now self-winding do the trick.
So… huh, I guess that in resumen I have nothing valuable to contribute. Oh well, I’m a charter member. 
Because a proper woman (back when button-sides were first standardised) had a maid to dress her, therefore the buttons are switched so it’s easy for the maid to do.
I’m a lefty and wear my watch on the right to keep it out of the way.
I am right-handed, and wear my watch on my left wrist.
However, my husband is right-handed and wears his watch on his right wrist. His right-handed father similarly wears his watch on his right wrist. I asked why this was, and it came out like the story of the woman who learned from her mother to always cut the pot-roast into two pieces to cook it, and it turned out that her grandmother didn’t have a pan big enough for a whole roast…
Once, years and years ago, my husband’s father broke his left arm, and couldn’t wear his watch on his left wrist. So he switched it to his right wrist and got used to having it there, and wore it there ever after. When my husband started wearing a watch, he wanted to be like his father, so he wore it on the right. He didn’t know why, until I asked, and he asked his father. He wears his watch on his right arm because his father got a broken arm once.
We all had a good laugh. But he still wears it on his right wrist.
Lefty here and I wear mine on the right. Like some others mentioned, I kept bagning it into things and scratching the face up.
People always thought I was weird when I wore it on my left.
I’m a righty, and I always wore my watch on my left hand, because it was easier to put on, and change the time. But I changed because it got in the way of my blocking glove when I was goalkeeping.
I am very left-handed. I do little with my right hand. I wear my watch on my right. I wear a watch with a stem, so when I wind it, I am used to turning my left hand into a claw to reach around to the far side of my watch to wind it.
**I wear my watch on the left when I travel to a county where they drive on the other side of the road ** than here in the US, such as Japan or England. I do this to send a constant message that something is different. The message I get is 'Look to the right before you step off the curb or you will die.'
I’m (mostly) right-handed, and I wear my watch on my right wrist.
I got my first watch when I was ten; and my father, a leftie, put it on my right wrist. After a period of not wearing a watch, I started wearing one on my left wrist. A few years ago I noticed that the skin under my watch was fish-belly white, while my arm and hand were tanned. I went back to wearing the watch on the right to even out the tan. For a long time, the watch migrated from one wrist to another, depending upon which hand I used to pick it up off the table in the morning. Now it’s on the right, and has been for about two years.

I’m a righty who wears his watch on his right hand.
I don’t know why, but it’s just more comfortable on that hand.
I’m a lefty, and I wear my watch on my left wrist. The watch never “gets in the way” or anything like that, and I find my left hand is more often in my sight range than my right, like in situations where I’m eating or drinking something, my hand is closer to my head thus putting the watch in my visual range more often.
I’m a righty who wears her watch on her right wrist. I do it because my dad wears his the same say (he’s a rightie, but he bats left handed!)
I am not sure why my dad wears his on the right, but I’d guess it’s either because of his dad, because of Vietnam or just cuz. Those are usually his answers for everything.
He also wears it with the face down. That I could never deal with. I wonder if it doesn’t bother him because he’s got huge wrists.
I’, right-handed, wear watch on left – because it’s easier to buckle the strap using my right hand.
I’m a (mostly) righty, and wear my watch on my right wrist.
I have done so since I got my first watch as a young child, and no one told me that it should go on any other wrist than the one it felt most natural to put it on.
I’ve had several occasions when a person looked at my watch and said “Ah, you’re a lefty, I see!” and a couple of other times when people try to convince me to switch hand. :rolleyes:
