A gold and pearl-set duplex pocket watch, signed and numbered Bovet, London No.274, c. 1820. The enamel dial is attributed to Jean-François-Victor Dupont, Geneva. The latter was famous for his portraits of eminent personalities (King George IV, Henry VI among others), as well as decoration of watches and boxes for the Chinese market. He worked frequently with Ilbery, Piguet & Meylan, Rochat Frères and others. Examples of his work can be found in museums, notably Geneva's Patek Philippe Museum.
