"One More Time" – St Pancras Railway Station, Euston Road, London, England

Dent was a London manufacturer of luxury clocks and watches, founded by Edward John Dent. Dent began making watches in 1814. Perhaps the company’s biggest coup is winning the contract to make the clock for the new palace of Westminster – or Big Ben as it’s more commonly known. Dent’s chronometers accompanied some of the 19th century’s most influential explorers. Robert FitzRoy took Dent chronometer no. 633 aboard HMS Beagle in 1831 the voyage that eventually led to the publication of The Origin of the Species – Darwin’s revolutionary theory of evolution. Two decades later, David Livingstone purchased Dent chronometer no. 1800 for his African explorations. And in 1890, the explorer H.M. Stanley was moved to write to Dent that "the Chronometers supplied by you, and which were taken across Africa in my last Expedition, proved a very great service to me and were in every way thoroughly satisfactory and reliable."

The Dent clock at St Pancras railway station is a reproduction of the original, destroyed in the 1970s, in part made from castings taken from the remains of the original. For much of the year 2015 a black-and-silver replica of the famous DENT clock dangled from the roof. The copycat chronometer was the work of Cornelia Parker, and was punningly known as "One More Time." It was a functioning timepiece; a horological redundancy; the embodiment, perhaps, of having too much time. In the artist’s own words: "The clock is the most conscious focus of a railway station, a dominant force. Everyone is watching the clock, checking if they are late. The piece will introduce the idea of a parallel frame of reference, that of a slower astronomical time."
