Link: Six Months with the Apple Watch
“At this point, I’ve removed most of the third-party apps and glances from my Apple Watch. Even with the native apps ushered in by watchOS 2, launching an application and waiting for it to load data is just too slow to be useful except in cases where I can’t get to my phone.”
I'm in a similar situation to Dan. At the moment I'm using the modular face, in white, with no complications except the date in the bottom right hand corner.
I use glances a bit more, but only the built in ones. Third party glances are just too slow to be useful. At the moment I'm using the media remote controller, the time zone, local weather, heart rate and settings.
