Jubilee Clock is a term used in reference to a number of clocks constructed and erected throughout the British Empire in commemoration of the Golden or Diamond Jubilee of various British monarchs, most commonly, Queen Victoria's.
Above the clock is a gilt copper sphere, a time ball that rises up a mast every hour and falls on the hour. The mechanism was taken out of use for many years because of noise complaints from local residents: it was renewed as part of a renovation of the Clock Tower and surrounding area in 2002.

The Jubilee Clock Tower, located in Maidenhead, Berkshire, England just outside the station in the town centre, was built as part of the nation's celebrations for Queen Victoria's Diamond Jubilee in 1897.
Building started in 1897 using money from public donations. The foundation stone was laid by then-mayor John Truscott on November 7, 1899. The tower was designed by local architect E. J. Shrewsbury, who designed many of the town's churches including St Peter's in Furze Platt plus the Technical Institute on Marlow Road. The clock tower was built by Charles Cox & Son; Charles Cox was the town mayor on several occasions.
The tower is approximately 14 m (45 ft) tall and has four illuminated clock faces each facing the four compass points. A diamond pattern on the clock faces commemorates the clock's function. The clocks were donated by Mr G. A. Battcock; they were made and foxed by Smith of Derby Group.
Red brick is used for most of the construction, typically of the local housing of that time. There is an elaborate pattern of stone work towards the top, just below the bell tower. All the clocks and bells still function.
The Newmarket Clock Tower is located at the top of the High Street. Local builder Richard Arber built it to commemorate Queen Victoria’s Golden Jubilee of 1887. The tower was paid for by public subscription, but local trainer Charles Blanton donated the clock made by Smith of Derby Group. The clock tower was officially opened in 1890. It takes 115 turns to fully wind the clock every week.
The clock tower was completed by Christmas 1898 and a clock made by Richard Robert Purchase, jeweller and watchmaker of Yeovil, was installed. A weather vane made by local blacksmith Albert Gabe was accepted by the Parish Council to complete the monument, and a Lime tree and privet hedge were planted behind the tower and iron railings with kissing gates erected at the front.
Erected in 1887 to mark the 50th year of Queen Victoria's reign the Jubilee Clock was originally positioned on a stone base on Weymouth sands, but in the 1920s the Esplanade was built around it to protect the sands from the encroachment of shingle from the eastern end of the beach. It is a Grade II listed building.
The clock is one of Weymouth's best-loved landmarks and has been a meeting place for generations of both locals and visitors. It is the focal point of Weymouth's New Year's Eve celebrations as midnight approaches and revelers gather beneath its four faces to welcome in the New Year.
Isle of Man
A Jubilee Clock is located in the Isle of Man capital of Douglas. It was donated by G.W. Dumbell in 1887 as a commemoration of the Golden Jubilee of Queen Victoria's reign. It is located at the foot of Victoria Street and Loch Promenade.
As can be seen from this c. 1900 photo, it originally had a horse trough and, hidden by one of those standing at the base, a drinking fountain above which is a plaque of Queen Victoria.
The 8-day clock mechanism used a weight descending in the column — originally the four clock faces were lit by small gas jets. Both mechanisms are now electrified.
