GALLET. A STAINLESS STEEL MANUAL WIND CHRONOGRAPH BRACELET WATCH Model: Excel-O-Graph Date: c. 1970s Movement: Cal. EP40.68, 17-jewel manual wind Dial: Tropical black Case: Stainless steel, snap on case back, no. 962067 Strap/Bracelet: Stainless steel expandable bracelet Signed: Case, dial and movement Size: 43mm Accompaniments: Maker's presentation box and booklet Footnotes: 'There's no room for error at 4,000 feet!' The Gallet Excel-O-Graph was designed as a practical instrument for aviation, navigation and other technical applications, combining a chronograph with a slide-rule bezel for calculations. The model forms part of Gallet's long association with professional timekeeping instruments, particularly those developed for aviation and other fields requiring precise measurement. Its historical production includes a wide range of chronographs and specialized timing instruments, while the brand's later Excel-O-Graph examples are associated with the Excelsior Park Caliber 40.68. The present Excel-O-Graph was offered directly from the family of the original owner, an atmospheric scientist and radar meteorologist who worked at the Air Force Cambridge Research Center from the 1950s through the 1970s. Having been well loved and worn by its owner during his years of use, the watch retains an honest character that reflects its history. This dial has developed an even tropical patina throughout, adding warmth and individuality to the otherwise utilitarian aviation design.
