Earnshaw chronometer No. 520

When Matthew Flinders set out in 1801 to circumnavigate Australia, he took with him a collection of five chronometers. The only one to survive the journey was this one. It was made in London by Thomas Earnshaw in early 1801. The escapement and compensating balance wheel which were invented by Earnshaw are incorporated into this chronometer and reflect his skill and precision in workmanship. Flinders expressed his enthusiasm for E520 in his book 'A Voyage to Terra Australis' where he referred to it as "this excellent timekeeper".
