... Its products now include its well-known chronometers, battery-powered ship clocks, ship’s bell clocks, barometers, barographs, thermometers, hygrometers, comfort meters to measure temperature and humidity, and wristwatches. ...Its products now include its well-known chronometers, battery-powered ship clocks, ship’s bell clocks, barometers, barographs, thermometers, hygrometers, comfort meters to measure temperature and humidity, and wristwatches. ...This chronometer was made around 1936 and has been on display at Flagstaff Hill for over 40 years as part of the exhibit of the ‘Reginald M’, an Australian-built, 19ss, coastal trader vessel. A chronometer is an accurate mechanical instrument used for measuring time. It is constructed carefully to remain stable even under the changing conditions of seafaring life such as temperature, humidity and air pressure. The Master or Navigator of a ship could use the chronometer and the positions of celestial bodies to calculate the ship’s latitude at sea. In 1905 the business Chronometerwerke GmbH was formed in Frankfurt, Germany, to supply the country with high-quality mechanical chronometers and ship clocks for their maritime trade, making the country independent of other international suppliers such as those in England. In 1938 the firm was renamed Wempe Chronometerwerke. The business continues today. Its products now include its well-known chronometers, battery-powered ship clocks, ship’s bell clocks, barometers, barographs, thermometers, hygrometers, comfort meters to measure temperature and humidity, and wristwatches. The company also performs chronometer testing facilities for the State’s Weights and Measures office. The article written by Givi in July 2022 “The Basics of Marine Meteorology – a Guide for Seafarers” refers to the weather’s signs and patterns being repeated over and over, and the recording of these observations helps forecasters predict changes in the weather. The chronometer is an example of a mechanical navigational marine instrument in use in the early to the mid-20th century. The maker is significant as part of a German government initiative to be self-sufficient in the production of good quality marine technology. This chronometer is significant as part of the exhibit, the Australian-built vessel, 1922 coastal trader ‘Reginald M’, listed on the Australian Register of Historic Vessels and on display for over 40 years.Marine chronometer or marine clock, brass case, glass cover, Roman numerals, 24-hour numbers beside them. Two black hands, a keyhole for winding and ventilation holes in the side. The base has a collar with four machined mounting holes.
