Да, кстати, вот историческая справка об этом нетривиальном мастере:
"
An exceptional education
The son of a watchmaking industrialist, Paul Ditisheim was born on 28 October 1868 at La Chaux-de-Fonds, the historical birthplace of Swiss watchmaking. Having completed his studies at the watchmaking school of La Chaux-de-Fonds, the young student went abroad to hone his skills at major watchmaking houses.
The most precise chronometers in the world
In 1892, Paul Ditisheim started his own business, Solvil, at La Chaux-de-Fonds. Thanks to his studies on the impact of atmospheric pressure and magnetic fields on watch movements, Paul Ditisheim contributed to the development of a new generation of chronometers that were the most accurate timekeepers ever designed. From 1895 onwards, he entered the competitions of the Neuchâtel observatory and set up a marine chronometry workshop in his factory. The house of Paul Ditisheim very quickly earned an excellent reputation among foreign observatories, and was awarded the world chronometric record by the Royal Observatory of Kew in 1912. He worked closely with the Nobel prize winner for physics, Charles-Edouard Guillaume, and is still regarded as the father of modern chronometers.
A hunger for research
In 1917, he decided to convert his business into a limited company. The Solvil & Titus company was born. He devoted the remainder of his life to research. From 1925 to 1935, he developed synthetic lubricants with the chemistry engineer, Paul Woog. He took refuge in Nice during the war, where he pursued his previous studies. He ended his days in Geneva, where he died in 1945. In 1962 the Solvil & Titus company released the Soltronic, an electronic miniature clock with no moving parts. Solvil & Titus now belongs to the Hong Kong-based Stelux Group."
