I don't think it's a woman's watch per say but I do think many of the photos I've seen of the 38mm and the 42mm are very misleading. The general consensus among people who haven't seen the watch in person has been, "the 38 looks less geeky/more manageable, and the 42 is massive".
I think after seeing the watch in person many people are surprised that the 42mm isn't really the monstrosity they thought it was going to be. On the contrary, I felt the 38mm was was smaller than expecting, especially in terms of the bands width.
That being said, they aren't feminine at all but I do strongly recommend men with wrist in the 160mm+ range to take a look in person. I could see a lot of guys who order the 38mm with wrists pushing 170mm+ being shocked come launch day
