An eight-day mahogany cased dial clock made by Brockbank, Atkins & Moore, London, number 11986, circa 1860.

This timepiece was made specifically for the Belle Tout lighthouse which was built in 1828 on the headland at Beachy Head, Sussex. Every lighthouse has its own signatory "character" (the sequence and frequency of flashes) so that mariners can identify a lighthouse from its signal. The clock has a subsidiary dial to help regulate the light to its original character of one flash every 15 seconds.

The Belle Tout lighthouse was frequently obscured by fog and in 1902 a replacement equipped with a fog horn was built on the foreshore. In 1999 the old lighthouse building was moved 50 metres away from the cliff edge and now serves as a hotel.
