At its surface, this post by Jason Snell for Six Colors is a detailed review of a specific Apple Watch face, known by the name Utility.

As an aside, you can find Utility, along with images of the rest of the built-in Apple Watch faces here.

But if you are new to Apple Watch (and who isn’t?), the post offers a terrific learning experience. Jason does a fantastic job of walking you through the optional settings available for Utility. For example, would you prefer a face with no numbers? Just a few? All of them? How about color?

More importantly, the post teaches you about complications, annotations wedged in and around the clock face, that do things like show battery life, phases of the moon, temperature, day and date, etc.

This one is worth passing along.
