I would have to agree with DanBC. Additionally, I am slightly confused as to how the idea/solution you've presented is different than from a military watch that has the numbers (often including the military / 24 hour time) as hour markers. Additionally, some of these even have the minute numbers labeled as well. So, that solves that "problem" (although I tend to agree with DanBC that you are exaggerating the thought process behind telling time).

You also mentioned having a separate minute dial. That also exists. There are watches with multiple dials, some for the seconds, others have dials solely for stopwatch functionality (chronograph watches).

Ultimately, I sort of see what you are saying, but I think if you do some research, you'll see solutions do exist.

Also, part of what makes people love watches (including myself) is the engineering behind them and the beauty of their design. For accuracy and functionality, I'll take my G-Shock over any analog (and automatic/mechanical) watch. However, I don't wear a watch purely for accuracy and functionality. They provide a bit of both, but there is more to it.
