Both. I keep swapping the watch from left to right, depending on what I'm doing, and don't bother to switch orientation. So when it's on my left wrist, crown is facing one way, and when it's on my right, it faces the other way. Doesn't really bother me which way the buttons are facing, it's as easy (or as hard) to manipulate either way. Ever since the iPhone got shortcuts to manipulate the watch, that became the main way I interact with my watch. I don't really use the crown anymore.
