Period
circa 1967
This open-face pocket watch chronometer is catalogued as a graduate's masterpiece produced at the Le Locle Watchmaking School by Jean Maurice Huguenin, dating to circa 1967.
Housed in a steel case measuring 62 mm across, it features a silvered dial inscribed 'ECOLE D'HORLOGERIE LE LOCLE'. According to the auction catalogue, the watch has a glazed screw back revealing a 50 mm bridge movement with lever escapement, Guillaume screw compensation balance, and a balance spring with two terminal curves. The source further reports an accompanying 1970 Neuchâtel Observatory rate bulletin documenting an average daily rate deviation of 0.06 seconds.
