ORIGINAL SEIKO SHIPS CLOCK - RAW STEEL

These vintage Seiko Ships Clocks were previously used aboard ocean-going vessels that have since been decommissioned. 
Originally operated using a 'slave' and 'master' system, these clocks were hardwired into the ship and controlled by a central 'master' clock to ensure every clock aboard the ship tells the same time as the ship entered different timezones.
Refitted with a battery operated Quartz movement, AA battery included.
Stainless steel / glass
Approximate measurements: Face diameter 18cm, frame diameter 23cm, 7cm deep
