Standardized Marine Chronometer

Standardization of the marine chronometer. The appearance of the marine chronometer standardized in the early 19th century. The movement of the timekeeper fits into a brass bowl with a glass lid. The bowl is suspended in a special brass collar made of two rings called gimbals. The gimbals fit into the wooden case to keep the chronometer level with the horizon, regardless of the ship’s rocking. Sometimes the wooden case fit into a wicker basket for extra protection. This chronometer is signed William Bond & Son and dates from about 1870.
