MARWICK & MARKHAM, London, 18th century Double-cased pocket watch in 18k (750 thousandths) yellow gold, very richly decorated both on the outer case with cut-out edges and enamelled on the closing line and on the watch itself. This abundant decoration is typical of watches dedicated to the Ottoman Empire, with the opaque sky-blue enamel giving it a slightly oriental flavour. The outer case features a plant motif on opaque green enamel, a lakeside scene with mountains in the distance, and a transparent to translucent pinkish-white enamel typical of Geneva creations. This enamel allows the sun's rays to be depicted thanks to the guilloché engraving on the back. The back of the watch is decorated with a bouquet of flowers ranging from peonies to forget-me-nots. The frame is in opaque blue enamel and also features lines of transparent orange enamel on an opaque pink background. Excellent condition. Manual mechanical movement with key (not present). Verge escapement movement. Fusee barrel. Lock signed and numbered 2139. Very good condition. Functional at the time of the appraisal. Gross weight: 62.5 g. Marwick & Markham were watchmakers who specialised in exporting to the Ottoman Empire. This is particularly evident in the style of engraving and decoration of their production. James Markwick, who was Master of the London Watchmakers' Company in 1720, became the business partner of his son-in-law Robert Markham, who succeeded him in 1730. However, even after Markwick's death, the company name retained the associated names. They were later joined by Story, Borrell and Perigal. Their watches are kept in many museums, including three at the Metropolitan Museum of Art in New York (17.190.1425 a.b; 17.190.1632 a.b; 83.1.78 a-c).
