Kendall was asked in 1770 to instruct other workmen on how to manufacture parts for additional replicas of H4; however, he declined stating that further replicas would "still come to so high a price; as to put it far out of the reach of purchase for general use". He assured the Board that he would be able to modify Harrison's design to build a similar but simpler watch for around £200, half the price of K1. He received the order and K2 was manufactured in 1771 (the date inscribed on the watch), and completed in 1772. It was given in 1773 to Constantine Phipps for its expedition for the search of a Northwest Passage, then it was assigned in North America. It worked less exactly than the original. William Bligh in his 1787 log of HMS "Bounty", recorded a daily inaccuracy of between 1.1 and three seconds and that it had varied irregularly.
