In total, Harrison received £23,065 for his work on chronometers. He received £4,315 in increments from the Board of Longitude for his work, £10,000 as an interim payment for H4 in 1765 and £8,750 from Parliament in 1773. This gave him a reasonable income for most of his life (equivalent to roughly £450,000 per year in 2007, though all his costs, such as materials and subcontracting work to other horologists, had to come out of this). He became the equivalent of a multi-millionaire (in today's terms) in the final decade of his life. Captain James Cook used K1, a copy of H4, on his second and third voyages, having used the lunar distance method on his first voyage.Captain James Cook, Richard Hough, Holder and Stroughton 1994.pp 192–193 K1 was made by Larcum Kendall, who had been apprenticed to John Jefferys. Cook's log is full of praise for the watch and the charts of the southern Pacific Ocean he made with its use were remarkably accurate. K2 was loaned to Lieutenant William Bligh, commander of HMS Bounty, but it was retained by Fletcher Christian following the infamous mutiny. It was not recovered from Pitcairn Island until 1808, when it was given to Captain Mayhew Folger, and then passed through several hands before reaching the National Maritime Museum in London.
