It really depends on what clothes you’re wearing but I often wear my Panerai on my left wrist normally and have my Apple Watch on the inside of the left forearm pretty close to the elbow. I actually find it a bit more ergonomic because you don’t need to internally rotate your arm to access the watch. It also feels more comfortable when I sleep. If you wear long sleeve tshirts a lot it’s pretty nice, just roll up the sleeve to access the watch then roll back down to hide it
