Deal Timeball is a Victorian maritime Greenwich Mean Time signal located on the roof of a waterfront four-storey tower. It was established in 1855 by the Astronomer Royal George Biddell Airy in collaboration with Charles V. Walker, superintendent of telegraphs for the South Eastern Railway Company. The time ball, which, like the Greenwich time ball, fell at 1 pm precisely, was triggered by an electric signal directly from the Royal Observatory.

Before it became a time ball tower, the tower was a semaphore tower used to signal to ships at anchor in the Downs or passing in the English Channel.

The Timeball Is programmed to drop every day at 1pm. Additionally, during the summer season (1 April – 30 September) the ball drops hourly from 9am to 5pm. The Timeball also drops at midnight on New Years’ Eve.  The drop cycle is as follows: At 5 minutes to the hour the ball goes half way up; at 3 minutes to the hour it goes to the top of the mast and drops on the hour. The drop cycle is automatic. The Timeball is controlled by the MSF Radio Time Signal transmitter located at Anthorn, in Cumbria.
