Pocket watch, J. Vrijthoff le Jeune (1646-1730), c. 1670 - c. 1690
The case of this watch is enamelled. The art of painting in enamel was perfected in the 17th century. A white ground was fired first. The next layer – consisting of depictions applied in tiny dots of colour – was then fired separately. Specialists in this complex technique were established in Blois and in Paris. The movement was made later especially for this case.
