Karrusel rough movement, No 30925 – Coventry work
Bonniksen stamped karrusel rough frame and carriage, circa 1900.
£345.00
Large hollow-back movement, the frame bearing Bonniksen’s PATENT stamp. No train, escapement parts or dial. 48.5 mm diameter.
Bahne Bonniksen, 16 Norfolk St, Coventry, Patent No 21,241 November 1892, inventor of a revolving carriage ‘karrusel’ in which the escapement and balance is made to turn 360 degrees in just under an hour (less in centre-second movements) in order to cancel out the deleterious effects of gravity in fixed escapement watches. Doing essentially the same as devised by John Arnold, and first made by A-L Breguet who called it a tourbillon, the karrusel differs in as much as the power of the mainspring drives both the carriage and the escapement. In the tourbillon the mainspring drives only the the carriage, the escape wheel pinion being driven by a fixed wheel mounted under the carriage – the karrusel does not have a fixed wheel.
NB: I purchased this movement many years ago along with another part-finished karrusel movement No 30924 that was engraved for Dent and bore their post-1922 28 Cockspur St address.
In good, complete but somewhat dulled and dusty condition having been in storage for over 100 years. A rare survival.
