This watch is accompanied by a letter from Alan Banbery of Patek Philippe, dated 28 February 1972, confirming that this watch was sold to James Ward Packard in June 1920 for approximately $200.
It is also accompanied by a Patek Philippe Extract from the Archives confirming production in 1919 and its subsequent sale on June 24th, 1920. The Extract also confirms that the watch left the factory with a silver and gold case and luminous numerals.
James Ward Packard, a Midwestern car manufacturer based in Warren, Ohio, is well regarded as one of the most careful collectors of watches in the early 20th century. His collection comprised some of the finest and most unusual complicated watches that had been made to that point.
It is interesting, then, that he also purchased this watch, a rather simple example cased in silver and gold (rather than entirely in gold). The dual time zone feature and luminous hands and numerals, suggest that this watch might have been used during travels. No matter where in the world Packard was, he would know what time it was back at home. If there was no electricity where ever he was, he could still tell the time with the luminous hands and numerals. The simplicity and utility of this watch might have been the very reasons he purchased it.
