No comparable examples to this exceptional pair of carriage clocks are recorded. Pairs of carriage clocks are exceedingly rare, whilst the combination of decorative materials used on the present examples (guilloché enamel side panels set in a case decorated with champlevé enamel and embellished with split pearls) appears to be unique. The case style is known and is customarily seen in this diminuitive size, with champlevé enamel and split pearls. See for example Fanelli & Terwilliger A Century of Fine Carriage Clocks, New York 1987, p.122. A comparable example was sold Christie's South Kensington The Dr Eugene and Rose Antelis Collection of Important French Carriage Clocks, 26 November 1998, lot 179. The sweep centre seconds hand may also be seen on these examples. Its presence suggests that the current pair were intended for the Chinese market.
