Funny. I think the modern buckle looks perfectly gender neutral. And as for that pic showing the buckle being oh so large, some of you seem to be ignoring that it's screwed up in terms of perspective due to being photographed so closely. This causes it to be seen as much larger than the elements behind it. Like photographing your own nose from 1 foot away.
Anyway, I think the SS + black modern buckle looks acceptably masculine. I do think the other colors are less so. I do not think it's the buckle that is the issue, but, the color choices. And frankly, the design of the clasp is the most interesting and appealing thing. The "classic" buckle offers zero design innovation and just looks cheap to me. And there is no way the milanese loop looks more masculine than this modern buckle. I mean, have you guys even seen this band style in real life? It's like a disco ball of specular reflections.
I can not accept the connotation that masculine has to be extremely tedious, boring, and featureless (i.e. either variation of the link band, 1980's Casio anyone?) or inelegant and cheap looking, not to mention annoying to take off every day (classic buckle) or utilitarian (rubber band.)
What's even left? The leather tank tracks on the oversized 42mm only?
Honestly, if you have any taste for a classy look and lack the overemphasized fear of not being a macho man randy savage, I think the SS + Black Modern Buckle is the best men's option. Of course, I also believe in the classic wristwatch sizing which basically amounts to, anything over 39mm is too big unless you're an elephant, so, whatever. I'm almost certainly getting the SS + Black Modern Buckle. I am fairly confident my beard will compensate for any mistake in perception of just how "feminine" that band is
(And yes, I realize OP is not concerned with looking masculine, not being a masculine individual and all, but, the conversation did go that way and I couldn't resist joining in.)
Oh and as a bonus, the manliest watch lover of all time, James Bond, wore this band style 90% of the time on his Rolexes:

So I think there's a lot more room for style choices than is being recognized here on a uh... nerd forum. Right. Just realized where I was participating.
