Citizen Maritime Radio Dial Clock – Green/Red Original Paint
Look closely at the dial of this clock and you’ll notice something unusual — two coloured sectors marked in green and red, sitting at precise intervals around the face. Those markings aren’t decorative. They’re the reason ships stopped talking.
The clock that kept the seas safe
From the earliest days of maritime radio, every vessel at sea was required to observe strict silence periods on the international distress frequencies. Twice an hour, all radio operators worldwide were required to stop transmitting for exactly three minutes and listen — so that any ship in trouble could send a call for help and know someone was listening.
The green sectors (h+00 to h+03 and h+30 to h+33) marked those silence windows on 2182 kHz, the international maritime distress frequency. The red sectors (h+15 to h+18 and h+45 to h+48) marked the corresponding periods on 500 kHz, the old Morse code distress frequency — observed simultaneously by operators in every ocean, on every vessel, in every weather condition.
This clock didn’t just tell the time. It was the visual heartbeat of a global safety system.
