It seems you didn’t follow the whole thread, with the discussion on using a compass watch both in Southern and Northern hemispheres. That the case back sketch itself was initiated to try and devise a reminder of a user’s manual for orientation.
If it were the case, you might have noticed that I preceded you in pedantry, having already mentioned the Russian naval tradition of marking marine compasses with the English initials NSWE while naming them with the purely Dutch words of Норд, Зюйд, Вест, Ост. I pray note that the one antique compass you show is a naval one, not a field one. As for “professional”, not heritage compasses, I’m afraid they’re called Glonas...
You might as well have noticed that I defended the use of English wording on the caseback, as least confusing to most users. Now, since this is a collaborative, i.e. consensual project, a majority seemed to favour Russian.
For the use, or abuse, of what are quotations marks, I understand your point, though I believe this watch is not the Elbrus, and its name could use quotes (скобки) — mostly for typographical balance as seen opposite to a longer text. And this without attracting someone’s radical ire.
For Южное полушарие, I would welcome any suggestion of a less confusing abbreviation. I say abbreviation or symbol, as squeezing these eight syllables in one quarter of a one-inch wide stamped surface may be... challenging.
Secondly, you say you find it generally confusing. Why, because in Australia, the sun zenith is North, so we’d write South. Hem. at top of the dial? Btw, while I’m not a native speaker of English, I can assure you you’ll never hear anyone say “I live in south hem”. Because this is called a written abbreviation, and it didn’t shock anyone here. Should I write Down Under (on top! ) and Here Normal, so it doesn’t disorient you? Fair skins / Dark skins?
As for the view of the Elbrus, I was confident we’d find at least one person to say it may be not correct because, maybe, viewed from the wrong side, so is it really properly oriented on the watch? Yeah, quite important, that. For my part, I may be interested in some details, but not to the point of neglecting the big picture, nor dragging things from moving.
