The time is displayed by simply adding the lights. 20 plus 10 plus 2= 32 minutes.
The Red Warning light is for the 6 hour mark and the Danger gauge for the other 6 hours. The watch measures 3.1 cm across by 4.1 cm long by 1.1 cm thick. The strap and case are solid stainless so a bit heavy. A very well made watch.
