Notes

Onesime Dumas, pupil of Auguste Louis Berthoud, Louis Berthoud's grandson and the nephew of Henri Motel was the first French maker to produce chronometers with a caliber drawn from that used in England. This is a very good example of this new production. It is interesting to point-out that even the box is of English type, with glazed upper part with hinged lid.
