Idk about upper middle class and what you’re putting into those words (AP/VC/rolex/actually many watches from this list ain’t middle class), but I wear one just fine (actually at work too because this thing is unbreakable and I’m not worried about destroying it there) and I wasn’t beaten up yet. The only reaction I got is “wow interesting, I’ve never seen a Russian watch”
Happy birthday! Cool watch, I’ve never seen it before
