In the middle of the junction is a distinctive ironwork pillar clock which has been one of the city's landmarks since 1901. Many Victorian and Edwardian photographs feature the clock at what was a busy tram hub. It was gifted to the city by Provost James Steel and Treasurer Robert Cranston, and was one of four similar clocks made by the Edinburgh clockmakers, James Ritchie & Son. The skeleton face and pillar were made by Macfarlane Castings. Originally a weight-driven pendulum clock, it was altered to a spring-driven mechanism in 1926. It and the clock at the city's West End were the largest street clocks in Britain to be driven by this type of mechanism. It was wound weekly by a clockwinder employed by Ritchie's, using a crank handle inserted into the base. In 1969, it was converted to an electric mechanism located between the dials. Junction improvements in 1974 led to the clock's removal, causing public consternation, as a result of which it was returned to a spot close to its original position.
