This confuses me too. I definitely think that there is a bigger market for women if the options were greater. Perhaps, its because with women, there are many more types of jewlery they can wear and they more often opt for the sparkley variety. If a woman wants to project success and wealth, she does it with a diamonds, not a complicated timepiece.
......The options for jewlery are more limited in men to watches (and gold chains and pinky rings.....if your into that sort of thing)
I think it takes a Y-chromosome to appreciate the beauty of a mechanical watch....
