I already wear all my watches on single pass NATO straps. I like being able to easily switch colors out multiple times a day.

Plain honestly. I prefer quartz and I usually wear nato straps anyway, so I never even see the back of the watch.

Lefty, I wear watches on my right wrist. I tried the left once but it just feels wrong. I also use my mouse with my left, so I don't have to worry about it dragging on my desk.

As someone who likes chronographs which tend to run a little bigger, most of my watches are in the 40mm-43mm range. That's about the highest I'll go.
