A copy of an elegant timepiece originally made in France, circa 1890. The apparent simplicity of the design is achieved by omitting a wheel from the more conventional gear train and making compensating changes in the tooth counts of the remaining gearing. The movement is hand made from solid brass, polished and gold plated.

A favourite of clock collectors, the Rolling Ball Clock was invented by Sir William Congreve and patented in 1808. The traverse of the ball along the grooves of the inclined platform regulates the clock by tripping the escapement at the end of each cycle and reversing the slope. The principle of the clock is such that the accuracy of the timekeeping is limited to +/- 15 minutes per day. The movement is hand made from solid brass, polished and gold plated.

The Grasshopper Clock is based on the first marine chronometer made by the world's most famous clock maker, John Harrison (1693 - 1776). His marine timepieces made it possible for seafarers to navigate accurately and can be viewed at the Royal observatory in Greenwich, London. The clock features the "grasshopper escapement" operated by two inter-linked pendulums that compensated for the motion of a ship. The movement is hand made from solid brass, polished and gold plated. The dials are silver plated with the seconds indicated by the scale above the clock face.Each clock is supplied with a copy of Dava Sobel's book Longitude that reveals the story of John Harrison's life.
