This 120mm Plastimo clock set brings together three instruments in solid brass: a clock, a barometer, and a thermo/hygrometer. The clock is available with a Roman numeral dial, with silent zones in blue and red for on-board radio use, or with a built-in alarm function. Convenient for those who sail in shifts and always sleep through their alarm. The barometer reads the atmospheric pressure, the thermo/hygrometer displays temperature and humidity, together providing a complete picture of the indoor climate on board or at home. All three instruments measure 120mm (3 inches) and are finished in brass, with a Roman numeral dial as a consistent style throughout the set.
