The modern aims of the company and its museum are charitable and educational, in particular to promote and preserve clockmaking and watchmaking, which as of 2019 were added to the HCA Red List of Endangered Crafts.

The museum collection includes John Harrison's sea watch H5, once personally tested by King George III.

The continued influx of newcomers led to resentment from those who had become established in London towards outsiders who came to set up in or near the City and who threatened their market.

[5] The charter gave regulatory authority to the Clockmakers to control the horological trade in the City of London and for a radius of ten miles around.

[8] The company bestows three awards for excellence: the Tompion Medal for outstanding achievements in horology, the Harrison Medal for the propagation of horological knowledge and its appreciation, and the Derek Pratt Prize for innovation, ingenuity, elegance, and the highest standards of workmanship and precision performance in the craft and science of time and timekeeping.

The Clockmakers Company is formally affiliated with the Antiquarian Horological Society, the UCL Observatory, HMS Protector, the Royal Navy's Ice Patrol Ship,[9] HMS Archer, a P264 Class University Royal Naval Unit based in Edinburgh, and XIII Squadron RAF.
