In excellent overall condition, especially considering the delicate nature of the filigree work. The watch would probably have been worn with the filigree case lined in richly coloured silk to match the owners attire. The cases originally housed a pre-balance spring verge. This has been replaced with a purpose made movement in about 1740 by Conyers Dunlop, an eminent maker of the period. At the same time a new dial, hands, gold pendant and protective outer case were fitted. The outer was almost certainly a replacement for a plain, pressed leather case which had protected the decorative filigree work for a century. It is unusual for a movement to be replaced in order to extend the life of a watch. More commonly a new case is fitted to the movement as this was the more valuable part
