Ulysse Nardin 8 day chronometer, caliber M.8.100
Pierre Béguin invented the 8 day chronometer around 1945 in Le Locle; the new type, which was to build on the advantages of the 2 day chronometer, was introduced with the intention of modernizing the range of the Nardin company. Its prototype was developed on May 7, 1943 and submitted to official tests from October 25 to December 27, 1943. The tests compared directly with those of the Neuchâtel observatory for the Bulletin de 1ère classe for marine chronometers and the required precision was achieved during the very first tests. About 80 copies of the caliber were produced between 1944 and 1963. Only a few of them were actually sold - not to a national navy but to geodetic institutes, a number of geographical boards and some scientific labs. The new product had been developed in a time of worldwide crisis, which made it extra difficult to judge the demand for a new caliber and make decisions on investments to be taken.
