If you're not familiar with the purpose of a radio room clock, the coloured segments each span 3 minutes and show the period during which radio silence is observed to listen for distress calls on the international distress frequencies.

The red segments indicate the listening periods for distress calls made with CW (morse code) and the green segments indicate listening periods for voice calls, usually on frequency 2182 kHz although other frequencies are also used.

Supplied in a single-watch travelling case with 24 months guarantee.
