Try it on - nothing beats the wrist test
Try it on - if it feels right, it is right.
I don't think size or men/women designation for a watch is what matters. I have an old 35.5mm Speedmaster which now I suspect women wear. My wife wears the 38mm women's model which I would actually not mind wearing if we had the same wrist size (adjusting the bracelet is a step too far in sharing). She also wears my old Rolex turnograph, although I would not wear her tiny 26mm oyster - got to draw the limit somewhere

This is not a feminine design IMO although the 5800 is more masculine with the bulkier looks. You may want to have a quick look at the 37mm Royal Oak if the Genta design appeals to you, which is not miles bigger, although I was surprised that it wears larger than I expected.
