June 2009 - Chapter 72 Meeting

Our bi-monthly meeting on the 7th of June was well attended with Ken Prentice talking about one of his passions "Guilmet and his Clocks." A Frenchman, Guilmet produced Mystery Clocks, the mystery being about how his clocks worked. A pendulum swings without any visible means of connection to the clock movement and is usually suspended from the hand of a graceful lady. Ken unravelled the mystery for us with examples and diagrams.

Ken shows how the Guilmet escapement works.

Carol Stapleton comprehensively covered the topic of diamonds, their gemology and uses in horology.

Carol was followed by Michael Neuman who works in the diamond trade, and he explained how they are graded and purchased.
