IMO, of course

Hi CL,
it's automatic - I like at least a little bit of "form follows function" and if you have a look at watches from the time when automatic winding eolved to be the norm you'll se that the crowns were getting smaller as well (so far that some earlier didn't even have one like the Harwood and some others were missing the winding train; i.e. crown was fro hand setting only).
For my taste the 5050 crown looks pretty balanced, could even be a tiny bit more "flat" .
A larger diameter crwon would look like wearing trekking boots and Armani suit
