He came while young to London, where he is supposed to have been a pupil of
James Macardell. He became a leading
mezzotint engraver. Watson published some of his works himself at his house in
Little Queen Anne Street, Portland Chapel; but the majority were done for Sayer, Boydell, and other printsellers. He exhibited engravings with the
Incorporated Society of Artists between 1762 and 1775. Watson died in
Fitzroy Street, London, on 20 May 1790. The engraver
Caroline Watson (1761?–1814) was his daughter and pupil. ==Works==
