A fine French 18 carat yellow gold open faced quarter repeating pocket watch with matching chatelaine and keys, circa 1850. This watch has a mechanical key wound movement with a cylinder escapement and a quarter repeating complication that sounds the hours and quarters on demand. It includes a double brass cuvette executed in the Breguet style. The gold dial features guilloché surfaces, engraved Roman numerals marking the hours within a smooth chapter ring, an outer minute track, and blued steel hands set against an applied multicoloured gold floral centrepiece, all enclosed by a richly decorated applied multicoloured gold floral border of fine green and rose gold foliage along the outer rim.
