In case you're interested in changing the orientation of your Apple Watch, follow the following steps.
Press the Digital Crown on your Apple Watch.
Tap on Settings > General > Orientation
I've had my Apple Watch with the Digital Crown on the left side so my thumb could engage the scrolling motion for the past 7 days and it definitely feels much more natural and comfortable. I'm sure Apple's default setting of having the Digital Crown on the right is due to essentially every watch throughout time having the dial on the right, but I really like this different orientation for my Apple Watch.
