A carved York stone baluster-shaped pedestal with stepped base and bronze sundial.
The dial plate shows the time at various international ports and settlements, including 'Pekin', Siam, Bengal, Fort St. George, Samarcand, Ispahan, Babylon, Aleppo, Smyrna, Buda, Danzig, Rome, Paris, Seville, Lisbon, 'Rio Janeiro', Cape Farewell (Greenland), Vera Cruz, Compostela, amongst others.
The gnomon is supported by a scrolling pattern and the lion rampant emblem of Belgium, surrounded by the Garter motto and surmounted by the royal crown of Belgium. The inclusion of the latter suggests the dial must date from after April 1831, when Prince Leopold of Saxe-Coburg-Saalfeld was invited by the Belgian government to assume the title 'King of the Belgians'. He retained ownership of Claremont until 1865, lending it regularly to his cousin, the future Queen Victoria, and her mother, after which date Queen Victoria purchased the estate. Claremont passed out of royal ownership in 1922.
