Very good comments by everyone. I think this is a question where there is no right or wrong answer. It's the old YMMV. Personally, I prefer watches in the 36mm to 42mm range. I believe that larger womens watches are fueling the still larger men's watch fad. But let's face it, in the past women's watches were ridiculously small. Which is why we see the emergence of Uni-sex sized watches. This category satisfies the too small womens issues as well as the too large mens watch sizes. There is my two cents, probably not worth that.
