The cathedral clock installed in the clock tower of St Paul’s Cathedral is one of our most celebrated and iconic public clocks. The original St Paul’s cathedral clock was installed in 1893 and is as reliable today as it ever was. To this day, Smith of Derby carrying on the tradition of maintaining the clock ensuring precision timekeeping is upheld in this very public clock.

With quarter chimes and hour striking the clock mechanism is now fitted with an electric winding system and the clock movement sits proudly in its 18 foot flat bed frame.
