I am excited to offer this beautiful Henri Jacot Grande Sonnerie carriage clock I have just finished restoring. I have given the 8-day movement a complete overhaul, and it runs and keeps excellent time. The clock offers three selections for striking that can be changed with a lever on the bottom: a "silent" mode, a "petite sonnerie" mode, and a "grande sonnerie" mode. The petite sonnerie strikes the hours on the hours and the quarter-hours on the quarter. The grande sonnerie strikes the hours on the hours and both the hours and the quarter-hours on the quarter. You can see the different selections at work in the video embedded below. There is also a repeater function which will strike the hours and the quarter-hours once activated.
The clock features a bamboo style gorge case measuring approximately 16.5cm (handle folded) x 10.5cm x 9.5cm. The white enamel dial features Roman numeral hour indicators, an outer track with five minute Arabic numeral indicators, spade hands, and is covered by a silvered mask. The platform escapement, also silvered, has a Breguet overcoil and a protective bridge over the regulator arm. The heavily bevelled crystals are perfect, aside from some (very) slight wear on a few of the corners. I have cleaned the case but left the original finish and subtle patina intact.
The serial number 8433 is stamped multiple times on both the case and movement. Going by some of the research done on Henri Jacot clocks this would place it approximately to the year 1892. The back movement plate is stamped with the Henri Jacot trademark.
