The Analog 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 Midi Ocean clock is a top-of-the-range instrument, aimed at smaller to mid-size vessels. It has black hands and numerals on white dial with a red sweeping hand and a mechanism that chimes 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. The case is a combination of machined solid brass castings, pressings and spinning, heavily stove-lacquered for a lasting finish. Quartz movement uses 1 x AA battery.
