Thomas Colley (d. 1771) was apprenticed by the renowned watchmaker Geo. Graham. After Graham's death in 1751 he went into partnership with Samuel Barcley, the workshop manager, signing their watches and clocks "Barcley and Colley Graham's Successors". When Barcley died in 1753 he continued working alone.
