I always struggle with escapements so any thing that makes them easier to understand is a bonus (click on the image)
A morning’s trawl of youtube very quickly turned up some fascinating short films about watchmaking. Here are just three:
And just in case you need an antidote to the smooth voice-over actors – here is a video from the swatch group featuring the late Nicolas Hayek about recreating the Marie Antoinette watch, which at the time had been stolen and apparently lost forever.
Our last meeting was given by Mr John Warner from Burgess Hill a member of the Sussex branch of the BHI and the AHS.
John comes from a chemical engineering background and lived in Rhodesia working for subsidiaries of Fisons and ICI. He served in both the Rhodesian Air Force and the Rhodesian Army against Robert Mugabe. Relocating to England in the 1980’s he has been a Company Director and a Management Consultant. He turned his horological interests from a hobby to a vocation and he is now a full-time watch and clock restorer. In association with Thwaites and Reed, has worked professionally on some very famous clocks.
In amongst the pile of flyers advertising fast food, double glazing etc. at SLBBHI towers this month was this horological gem and we thought it best to share.
East Grinstead Museum are holding an exhibition of local clockmaking, running from February 6th through to June 2nd, and you can download the PDF advertisement using the following link:
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.
Using state-of-the-art technology to look inside a watch and a musical pig without even opening the case!
The hour that we put in the ‘bank’ last spring will be handed back to us at the end of the month.
To celebrate there will be a clock-related event at the foundling Museum in London. Please click on the images below to enlarge the leaflet and find out more.
On behalf of the late Messrs. Willet and Hudson, we hope that you enjoyed the extra hour of evening daylight this summer.
