S. Smith & Son, London
- A FINE AND RARE 18K YELLOW GOLD OPENFACE KARRUSEL POCKET CHRONOMETER
1899 NO 239-3
- diameter 56 mm
The karrusel watch is almost exclusively produced with lever escapement. The present watch is possibly one of four chronometer escapements in a series starting with the number 239 made by Smith. A similar watch by this maker with spring detent escapement was offered at Sotheby's London, 25 October 1979, lot 205 and was numbered 239-4.
Bahn Bonniksen of Coventry invented the karrusel watch and patented the device in 1892. Like the tourbillon devised by A. L. Breguet, the karrusel has a revolving escapement. The primary difference between the tourbillon and the karrusel is that the karrusel escapement is driven by the train, independent of the carriage/platform. This allows for a simpler solution for the correction of positional errors.
