I'm guessing that putting an equal number of links on either side, never mind the asymmetry of the clasp, has worked out for them (watch manufacturers) for quite a while, and these days they prefer not to think about it too much anymore, because it makes their brains hurt.
There's probably some argument that can be made based on the thickness of the ulna and the radius, but - oooh, my brain! Sorry, you have to figure it out for yourself. Just don't scratch up the watch band. You can also switch sides - I think most of my watch clasps are mounted opposite of what your pic shows. If you do that, don't scratch up the watch lugs.
Also, it's a bit like trying on shoes - what fits in the morning might not fit in the afternoon - that (and Corona) is why a lot of people here switch watches at noon.
Edit: just checked my Omega (because I don't have anything better to do, apparently), and I'll be darned, it is mounted with the clasp orientation like in your pic: six-and-a-half links on the six o'clock side, and five-and-a-half on the twelve o'clock side, with the six position adjustable 1154 clasp (w/o diver extension). With that clasp there are no links hidden under the clasp.
I know you just bought the watch, and you aren't even allowed to wear it (or are you now? I thought it was November?), but it's never too early to start thinking about whether you need an adjustable clasp. It's also a lot cheaper than starting to think about whether you need a second watch.
