Founded in 1755 Vacheron Constantin stands as the oldest watch manufacturer in Geneva. Fifteen years after its founding this famed firm produced its first complicated timepieces. Over the years of its uninterrupted production, Vacheron Constantin has remained dedicated to being at the forefront of technical innovation and design as the company motto indicates. “Do better if possible and that is always possible”. At twenty-four years old Jean-Marc Vacheron established his workshop in the Swiss quarter of Saint-Gervais. In 1785 Jean-Marc’s son Abraham took control of the company and in 1819 Vacheron formed a partnership with Francois Constantin giving us Vacheron Constantin.

This watch is without question one of the most significant Vacheron Constantin watches to ever come to market. The watch, manufactured to Packard’s specific instructions, is unique in every way. No other clock watch with trip repeat, grande and petite sonnerie, chronograph and half quarter repeating is known to exist. Due to the complexities of making a clock watch, manufacturers or the collectors ordering such watches would always add moon phases and a perpetual calendar to the package.
–
It is interesting to note that the other known clock watches manufactured by Vacheron Constantin are in addition fitted with a perpetual calendar and a split seconds chronograph. Other significant Vacheron Constantin watches to be offered at public auction in recent years include those made specifically for King Farouk of Egypt during the early 20th century.

James Ward Packard, one of the most influential collectors of our time, purchased watches manufactured by the most exclusive manufacturers. There is no documented account of exactly how many watches Packard purchased and from which firms. The present watch, unrecorded or documented in any literature, confirms that Packard did not only buy Patek Philippe watches but he also viewed Vacheron Constantin with the same reverence. According to Vacheron Constantin’s record books the present watch, manufactured with blue enamel monogram and forged from 20k gold was sold to Packard in 1919 for 3,320 Swiss Francs.

In exceptional overall condition, the present watch has been stored away for over 60 years with no human contact at all. It may also be assumed that the hand written operating instructions could have been drafted by Packard’s own hand.
