Paul Ditisheim, born in 1868 and died in 1945, was one of the most important Swiss watch and chronometer makers. He researched and published primarily on topics of precision time measurement. After training at the Watchmaking School in La Chaux-de-Fonds, he worked in Ponts-de-Martel, Berlin, Paris and Rotherham in Coventry. In 1892 he opened a watch factory in La Chaux-de-Fonds and soon became one of the most successful pocket and on-board chronometer makers, winning numerous first prizes in countless competitions.
