The Worshipful Company of Clockmakers is one of the Livery Companies of the City of London. The Clockmakers were formed by a Royal Charter in 1631. Originally, no person was allowed to sell clocks unless a member of the Company. However, such requirements have been relaxed and removed. The Company now exists as a charitable institution, as do a majority of Livery Companies. The Clockmakers' Company ranks sixty-first in the order of precedence for Livery Companies. Its motto is Tempus Rerum Imperator, Latin for Time Commands All Things.
