If you have the Utility face with all 12 numbers displayed, you should see that the 12, 3, 6, and 9 "fly in" twice whenever you slowly scroll into the watch face from the home screen.
It's pretty easy to speculate what happened since you can have the Utility face show only those four numbers instead of all 12.
Edit: I shot a video that demonstrates the bug. Brookzy (below) posted a GIF that also demonstrates it, although he/she is scrolling too quickly to easy notice it (it is barely visible in his/her GIF).
