Schatz 1881 Schatz Royal Ocean Tide Clock

Schatz, founded in 1881, are the world's leading manufacturer of classic ship's clocks, barometers and associated instruments and have supplied both commercial and naval fleets for many years. The case is a combination of machined solid brass castings, pressings and spinning, heavily stove-lacquered for a lasting finish. The white face, with black hands and Roman numerals, is viewed through a substantial glass opening port with a brass cleat fixing. This allows access to the movements for battery changeover or adjustment without removal from the bulkhead. Swiss made. Tide clocks provide an at-a-glance indication of tidal state by means of the blue hand, showing high, low and half-tide. They work by following the lunar cycle approx. 12. 5hrs thus reflecting the main influence on the tides. Quartz movement uses one AA battery. Diameter 18 cm.
