So there's an active thread about a fellow who unwittingly purchased a watch that is listed on its manufacturer's web site in the ladies section. Someone posted a picture of it and, frankly, maybe I'm testosterone challenged, but I'd probably buy it for myself (and I have both x and y chromosomes btw). That thread is dwelling on whether or not he was purposefully misled, but I want to explore the related question of just what is it that undeniably differentiates a man's watch from a woman's watch, regardless of where the manufacturer posts it on their website.
I think I can only say it's the size. Maybe 36mm and smaller is women's and children's. But case metal, color, number of subdials, color of strap, presence of precious gems, crown on left v right, whatever -- I think I could find a guy's watch that meets whatever else might be offered as a gal's by description.
So, short of internal vs external whizit (trying to be family friendly) anatomy, what determines the gender of a watch? What would you have to see strapped to a guy's wrist to cause you to question their true manliness?
