By 1730,
enamel dials were common on English pocket watches. There were sometimes produced in the 1780s for longcase clocks, but are very rare. More common are painted enamel dials on longcase and bracket clocks, fitted to high quality pieces. Enamel sections are most frequently found on French clocks. Often the dials are gilt, with the numerals set against enamel reserves. Enamel dials are extremely prone to cracking and chipping, so examine examples very carefully. Hairline cracks are often camouflaged by bleaching but you should be able to spot the differences in colour. Cracking crates a cobweb effect over the dial and if you come across this, the price should reflect the damage that has occurred.
