Paul Ditisheim (1868-1945) was a renowned Swiss watch and chronometer maker who specialized in precision time measurement. After completing his training at the watchmaking school in La Chaux-de-Fonds, he worked in various cities such as Ponts-de-Martel, Berlin, Paris, and Coventry. In 1892, he established his own watch factory in La Chaux-de-Fonds, which became highly successful and won numerous first prizes in various competitions. While his impressive deck watches are frequently found in the market, his ship’s chronometers, which often come with certificates from the chronometer competitions, can fetch high prices. This chronometer even participated in the 1908 competition in Neuchâtel, where it was regulated by Bourquin.
