This exquisite timepiece was likely created for the Italian market, as there is a brass signature plate affixed to the case cover that reads Cronometro Di Marina. The chronometer was crafted by Paul Ditisheim and his company, Solvil, in La Chaux-de-Fonds and sold to Maurice Ditisheim.

In 1858, Maurice Ditisheim established his own business in La Chaux-de-Fonds, where he produced top-quality pocket watches under his own name. His timepieces were renowned for their precision and exceptional quality. The workshop quickly grew into the Maurice Ditisheim manufactory. In 1894, Gaspard Ditisheim introduced Vulcain watches for the first time. In 1900, the Maurice Ditisheim company registered Vulcain as a brand name for their watches.
