A gilt brass carriage clock in Corniche case with white enamel dial and blued steel hands. The movement is unusual, in that it repeats the full quarters and hours on demand as a grand sonnerie would. But strikes the hours at the hour, and the hours and quarters at the half hour during normal running. During servicing we found no filled holes or pins missing, so this clock must have always been set up this way and sold as this. Interestingly Leigh Extence in his 2013 ‘Jacot Catalogue’ describes two examples of half-hour sonnerie striking that he has identified as peculiar to Henri Jacot;“This style of strike would appear peculiar to Jacot, in which there is grande-sonnerie strike, but only on the half-hour rather than all the quarters, as is normal, although a few other examples by other makers have since been examined. This allowed for an extra complication without the need for the larger barrel required for the extra strike on a grande-sonnerie.”Leigh Extence ‘Jacot Catalogue’...
