Some are. I'm a lefty who wears watches on the left wrist, and don't need much dexterity in the right fingers to be able to navigate the watch. It's not like writing, which requires far more finger precision.Lefties are adaptable.
I prefer to wear my watch aft of my wrist bone (away from the hand), but it seems the try on appointments are often placing the watch over the wrist bone or on the hand side of it, leading to potential discomfort and accidental button presses. Funny, as I thought it was common to wear a watch they way I do, but maybe that is just me. My wrist is at its narrowest aft of the wrist bone, so it is a very comfortable way for me to wear a watch.I plan to wear it with the crown on the lower left but when i tried in the store at my appointment I could sure feel it digging in to the back of my hand every time I flexed my wrist. Hope I get used to it.
