You can argue about the ergonomics since there isn’t a scientific comparison to compare but It’s simply much nicer aesthetically having a round watch on your wrist vs a giant square shaped one that resembles a geeky device rather than a sleek watch.I would like some more basis on how round is more ergonomic that rectangular or square, how can round fit be more ergonomical when a screen with pixels is laid out in a rectangular format (HxV pixels) ?
That’s all.
proof of that is the fact that over 90% of mechanical watches (specially premium ones) are round not square.
also almost all function focused watches (fitness/sports/diving/aviation/military /hunting etc) which tend to be large are round as well.
