The present watch is a lovely example of a time only open face pocket watch that goes beyond the ordinary to the extraordinary, with an “Extra” movement and Guillaume balance. According to the extract, the watch received a rating certificate from the Geneva Observatory on January 16th, 1914. The cuvette reads “Made for Edgar C. Stiles New Haven Conn. 1916 by Patek Philippe & Co. Geneva”. An internet search finds the Stiles family spread out across New England, and today there is an Edgar C. Stiles elementary school in New Haven, Ct. The movement further signed The Ford Company New Haven, Conn., which presumably is the retailer, however there is no record of the firm.
