The two most complicated watches of all time were made by Patek Philippe. The first, made for Henry Graves Jr. New York, was completed at the beginning of the century, and the second, the Caliber 89, the world's most complicated watch, completed in 1989 (hence the name) to mark the firm's 150th anniversary. In 1932, Patek Philippe changed hands, and its new owners became Charles and Jean Stern. Today the third generation of this family sill owns and manages the company. Shortly after world war II, Patek Philippe established an electronic division, and in the 1950's the company pioneered quartz technology, filling several patents and winning multiple awards. Today, Patek Philippe SA, Geneva, is still a family company, owned jointly by its president, Mr Henry Stern, and his son and Vice President, Mr Philippe Stern. The firm has traditionally made complete timepieces, watches and clocks, employing craftsmen who are master-watchmakers capable of designing and finishing the most complicated watch movements.
Other specialists such as goldsmiths, chainsmiths, enamellers, jewelers, and engravers complete the firm's manufacturing capabilities. Although Patek Philippe is rightly famous of the leading manufacture of mechanical horology, the firm is also the forefront of the industry as producers of industrial and electronic timekeepers, with its highly accurate master-clocks installed in power stations, hospitals, airports, and other public buildings and factories. The firm clientele has included many of the famous figures across history, including royalty such as Queen Victoria, as well as distinguished scientists, artists, authors and musicians, including Albert Einstein, Marie Curie, Charlotte Bronte and Tchaikovsky. Today, clearly most of the firm's production consists of wristwatches, but Patek Philippe retains the ability to produce pocket watches,and clocks to order, from highly complicated movements to those decorated with enamelled miniature paintings and engravings. The company continues to patent new inventions and improvements in horology and plays an important role in maintaining the quality , prestige and reputation of the Swiss watchmaking.
