Schatz is the leading manufacturer of classic ships' instruments, and one of very few that still make the mechanical chiming movements that were so familiar to the naval and merchant seaman of 100 years ago. 

They can sound out the fascinating "Ship's Bells" watchkeeping system of four hours on four hours off, striking one bell after the first half-hour, two after an hour and so on until the end of watch "eight bells" - time to change crew and start the pattern again. 

This electronic Royal Ocean Clock is powered by one AA battery which keeps the quartz clock and Ships' Bells striking movements running for a year.

The intricate workmanship is protected in stove-lacquered, solid brass cases or with thick glass ports, secured by brass scuttle clamps. They have black hands and numerals on white dial with a red sweeping hand (not illustrated). 

Measures: case diameter 7" ( 18cm ), clock face diameter 5"( 13cm ), depth 4" ( 10cm ).
