The Venus Watch Co. was founded in La Chaux-de-Fonds, Switzerland, in 1902 by Paul Arthur Schwarz and his wife Olga Etienne-Schwarz. Most any seasoned collector recognizes Venus for their manufacture of chronograph movements, sold to other watch companies. The Ranftt web database records 22 separate Calibers of Venus chronograph movements made between the 1930s and ‘50s, some of which are still in use today.
But did you know that Venus was also a manufacturer of finished watches signed with their own company name? They were regular exhibitors at the Basel Exposition in the 1950s, and ran ads in the trade magazines, notably Swiss Watch and Jewelry Journal. Attached are a couple of those ads.
I have seen numerous examples of many types of Venus watches, including multi-date and even dive watches. Vintages can be seen all way into the 1960s. Cases are typically chrome or other type of base metal, but I have seen a few karat gold cases as well. Ironically, most movements I've seen in non-chronograph specimens are sourced from other ebauche suppliers, such as Fontainemelon and others.
