 Today I noticed that my SSU screen had gone blank. After 30 seconds I saw the clock again. Cannot tell if it was rebooting or not because I was bust at work. 
 How can I check what has happened?

 @yannis-belouris it is power saving thing called stand by mode, leave watch for few min on the table and you will see the same

 @slashas wow. I never stop wearing the watch and I have seen it only a couple of times. Thank you

 @yannis-belouris I’ve seen many times while sitting in the office, normal behaviour, once watch detects movement watchface is engaged.
