Gold and enamel cased duplex watch. Expensive watches with elaborate gold cases were made and finished by highly skilled craftsmen based mostly in Clerkenwell. The watches were often engraved, decorated with 'engine-turned' patterns and enamelled. Some had borders picked out in different-coloured golds. The regulator of the Spencer and Perkins watch (with its separate case made of horn) is inscribed with the Spanish words for fast and slow, suggesting that it was made for export to Spain or South America. The very costly and intricate watches by William Ilbery were probably destined for the Orient.
