Description from the seller
Vintage ship clock – Radio Silence Clock
Special vintage ship clock from around the 1980s, originally used aboard cargo ships and supertankers as a slave clock. These clocks were driven from a central master clock and formed part of the time-registration system on board.
This specific piece is a so-called radio-silence clock. The sectors on the dial indicate the periods during which ships had to observe radio silence, so distress calls such as the international SOS signal would be more audible on the international maritime distress frequency of 500 kHz.
The clock is made of glass, metal and vitreous enamel and has a characteristic maritime appearance.
Dimensions:
- Length: 21 cm
- Width: 21 cm
- Height: 8 cm
The original movement has been replaced by a modern quartz movement, which runs on one AA battery. The clock is therefore immediately functional and can be used as a decorative object.
A special item for enthusiasts of maritime memorabilia, ship interiors and vintage industrial design.
The photos are sample photos; the actual clock may differ slightly.
The clock is carefully and with care packed and shipped with Track & Trace.
