The Beverly clock was featured on Seven Sharp – The clock that doesn’t stop!
The Beverly clock on the 3rd floor of the Physics Department is powered by atmospheric pressure changes and has run continuously despite not being manually wound since its construction by Arthur Beverly in 1864. As one of the longest running experiments in the world, it predates even the founding of the University of Otago in 1869.
