When switching to 12h mode additional space is needed to draw AM/PM besides the seconds. So I could not only increase the size of the seconds font but also have to increase the size of the AM/PM font and the font for the calendar week which would make the watch face pretty packed.
In addition every new font means more memory consumption so it's not that easy to realize.
Nevertheless I will try to find a way to increase the font size.
