Daniel de Saint Leu (active 1753-1797) Of Genevan origin. He worked in Geneva and London as a watchmaker to the Queen in 1765, Saint Leu was renowned for very fine enamelled and varicoloured gold clockwatches set with diamonds and precious stones, and repeating watches for the Turkish and Islamic markets. He also made a magnificent silver mounted clock for the Court of Spain. Although de Saint Leu himself was only active until about 1797, the company continued to make watches under his name for roughly another 15 years.
