Master Clock System by SEIKO

A Master clock system is necessary to keep correct local time updated when a ship is moving in different time zones, as well as keeping the correct GMT (UTC) time. The master clock, due to its accuracy, also has a chronometer function.

Uller International Communication has a long experience with the high quality SEIKO Master Clock systems, which we distribute. The Seiko Marine Clock is literally the result of Seiko’s many years of experience and achievements in its determined pursuit of accuracy and reliability. Highly accurate crystal is built in and a Secondary Clock group inboard is driven by the signal of accurate time. Signals for loggers are available.
