The Seiko radio room clocks are ship clocks with classical design and clock faces with green and red radio sectors made for use by the radio operator and captain in the radio room and bridge respectively. These colours indicate the period of time in which only emergency calls are allowed to be made via radio communication and all other radio traffic must stop.

The radio sectors from minutes 1 to 3 and 31 to 33 are marked in green and indicates the time of radio telegraphy, while the red sector, minutes 16 to 18 and 46 to 48, stands for morse communication.

These clocks were originally slave clocks which were tied to the ships central clock and were always correct even when switching time zones. This reduced the need for manual labour to switch every clock on the entire ship every time the ship moved to a different time zone. We have converted these to run on a reliable AA battery powered quartz mechanism. 

Manufactured circa 1990's these beautiful Seiko clocks are proving extremely popular, yet so rare to procure. 

These were originally slave clocks and were all connected to the the master clock in the captain’s cabin so that he could change the time of every clock on board as the boat entered a new time zone.  We have converted these to run on two reliable AA battery powered silent quartz mechanisms. A small knob on each face will unscrew to open the sides of the clock face to unveil this. 

In 1881 Kintarō Hattori from Tokyo introduced one of the first quartz watches, from then the brand Seiko has been known as a super high end manufacturer of time pieces both watches and clocks. The quality of Seiko is so high it was the official manufacturer of watches for Japanese soldiers during world war II
