History and description
The clock is thought to date from around 1484. The outermost numbered circle of the main dial is decorated with afleur-de-lis
The fleur-de-lis, also spelled fleur-de-lys (plural ''fleurs-de-lis'' or ''fleurs-de-lys''), is a lily (in French, and mean 'flower' and 'lily' respectively) that is used as a decorative design or symbol.

. The Earth is represented as a fixed golden ball in the centre of the dial. The Latin inscription "Pereunt et imputantur" below the main dial may be translated as "The hours pass and are reckoned to our account".
A small bell located behind the clock dial chimes the quarter-hours. On the hour, this is followed by the striking of the Peter Bell in the tower above.
In 1759 the smaller upper dial was added, with a single hand to indicate the minutes.
The clock-room is behind the dial on the north wall of the transept, and still houses the clock mechanism. Access is via a doorway visible in the stone wall directly beneath the clock. Legend suggests that the round hole cut in the bottom of the door was for the cathedral cat to gain entry to keep the clock clear of mice and rats. The modern clock mechanism was installed in 1885 by Gillett & Bland of Croydon.
