A clock by John Thwaite was installed in the north west tower in 1775.
This was later improved by Benjamin Vulliamy and moved to the broad tower around 1835.
It was replaced in 1880 by a new clock under the instruction of Edmund Beckett QC.
The clock was built by Potts and Sons of Leeds.
Cambridge Chimes were a feature of the new clock.
The clock featured a double three-legged gravity escapement to the designs of Edmund Beckett.
The machinery weighs about 4 long tons (4.5 short tons), with the driving weights being 1.5 long tons (1.7 short tons), suspended by steel-wire ropes 270 feet (82 m) long, and the pendulum weight of 2 long hundredweight (100 kg).
The beat is 1.5 seconds.
The hour hammer is 224 pounds (102 kg), striking upon Great Tom.
The striking trains require winding daily, when done manually it took 20 minutes.
The going train required winding twice per week.
The clock mechanism contains the inscription Quod bene vortat Deus Opt.
