What was the role of the Larcum Kendall K1 chronometer?

During James Cook's second voyage from 1772 to 1775, the Larcum Kendall K1 chronometer was successfully employed to calculate longitude. William Wales used the instrument while logging locations, conditions, and testing navigational equipment. This deployment helped support the broader expedition commissioned by the British government and the Royal Society to determine whether a southern landmass existed.
