It's been interesting to read comments on the 38mm watch. Alot of people think it looks ok on someone else, but a lot of guys see it on their own wrist and think it's too small.
My theory is the watch looks smaller when you see it from an angle. If you look down at your wrist, you don't see it head-on. However, other people (and watch "selfies") tend to be seen "head-on". From that perspective, the watch sits in the middle of your wrist and can be judged a little better. It looks larger from this angle.
So in short, the way you see it from above, is different from how other people see it from across the room.
Conversely, the same principle is at work with the larger 42mm on smaller wrists. The user think it looks ok on their wrist but other people from across the room see it as too big.
Here is my attempt to illustrate the different perspective with my 38mm watch on my 165mm wrist.
