This is what happens when I try to take a short cut. Yes, the text is adjustable. The 38mm just doesn't support larger text as well.

Strictly speaking, numbers aren't text. Still...
I believe larger text on the 42mm will be larger than larger text on the 38mm, in some if not all cases. So consider my 'larger text' to be 'larger text is better supported on the 42mm Watch's greater real estate'. Or don't.
