The Greenwich Time Ball Douglas Bateman
The time ball talk will cover the invention of the ‘instantaneous signal’ by Captain Wauchope leading to its construction in 1833, followed over the years, by many modifications. Douglas will bring us up to date describing his installation of electronic control in 1991 and now with a radio controlled clock that gives automatic changes to summer time and back.
Douglas has been involved with precision timekeeping since building a regulator with photoelectric ‘escapement’ and circular error control. The led to the use of the time signals from Rugby and publication of articles about the clock and the importance of a term called Quality Factor, Q, which related accuracy to the property of the oscillator.
His current project is to write a comprehensive history of the Greenwich Time ball involving examining the Greenwich archives in Cambridge and The National Archives at Kew and elsewhere, and with assistance, examine more or less every detail of the current machinery.
The Tail of Two Cities & The Rode to Ruin
Join the distinguished turret clock specialist, Peter Watkinson FBHI, to hear about the making of two extraordinary exhibition tower clocks and the challenging restoration, automatic winding and re-siting of a third.
Peter studied horology at Hackney technical college in the early seventies and for a number of years was foreman at Gillett and Johnston. Today he works as an independent maker and conservator of turret clocks.
Peter will be discussing the challenges that he faced making these two clocks, the methods that he used in to overcome the difficulties of clock making on a larger scale and the perils of letting one’s enthusiasm get the upper hand! Peter will also be discussing work on a third clock and will be revealing whether or not the ‘Rode’ led to ruin.

The Life and Times of Edward East.
Oliver Cooke studied the conservation and restoration of antique clocks at West Dean College, West Sussex, between 2005 and 2007. He became an assistant curator in the Horological Section of the British Museum in 2007 and has been a curator of horology since 2008.
Edward East was one of the most successful clock and watchmakers of the seventeenth centaury he was watchmaker to Charles the first. He was twice master of the Clockmakers Company 1645 & 1652. That he lived to the age of at least 90 and through some of the most significant events to our history, Cromwell and the Civil War, Plague, and the Great Fire of London must have had effects to his horological business. Oliver has studied many of the clocks and watches that have been found to date and shared with us the knowledge he has gained of this little researched master clockmaker.
