"Smiths had an excellent reputation for their clocks, some of which were quite specialised and collectible. This watch is faithful reproduction of the radio room clock pictured below.



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