The 10 Seconds Test for Watch Apps

Created this graphic to indicate the time taken by the Apple Watch to accomplish the task.

Personally I feel, Apple Watch apps have a very small window for usability. If the app involves just glancing, I think the time on this dial should be even shorter (i.e. 2-3seconds) and if it's a single button action, I feel that the time that the app takes to accomplish a task should be within 10 seconds, with minimum interactions.

Created this graphic as a badge to indicate that the app passes the 10 seconds test.
