Notes

The movement of this watch vvas left unfinished by Louis Berthoud in 1799, at the time he stopped producing the "Montres Marines portatives au gousset" in favour of the "Montres Marines à suspension". It was specially completed at the request of M. le Général Cafarelli, then Prefet Maritime de Brest. Previously in the Hurle Bath collection, this watch is described by George Daniels and Cecil Clutton in Watches, 1979, fig. 225 a-b. It is illustrated in J.C. Sabrier : The Longitude at sen in the time of Louis Berthoud and Henri Motel, Antiquorum Editions 1993, pp. 126 - 127 and 529.
