In Xcode under Devices I can see my iPhone and the paired Watch information. I can see the log for the iPhone but I can't find anywhere to look at the log for the Watch. Is there a way to view the console log for the Watch?
Viewing console log for Apple Watch
I don't know if there's an easier way, but I found an iPhone app called "System Console" that displays all log messages from both iPhone and WatchKit apps. Even if there's a way to do it in XCode, the System Console app displays the log messages in real time in a relatively non-envasive manner (Disclaimer: I have no connection to System Console or its authors).
I can see watch logs/app crashes within the iphone's logs accessed from Devices in XCode
