Check what software version

The forum thread states Software Version 19.18 is the latest for the 165 but I am unable to find this anywhere on my watch it says I am on 6.08 brand new out the box.

It also says to go to 

  • Menu > System > Software Update > Check For Updates

This only gives the option to turn Auto update on or off not to check for updates, am I looking in the wrong place?
