It’s all a personal choice, but for me the indentation in the 6 o’clock chapter ring isn’t disruptive to the aesthetics. Of course I own a 5270 with the chin too, and not being off put by it I actually believe there’s unique value in these dial variations. I also don’t see the 5 and 27 as all that impactful. My preference would have been uniform sized numbers but it’s not dramatic. Ultimately the modern size, functions, and pusher through the crown supersede any misgivings about the dial nuances.
