"The inexpensive brand Patria was registered by the Brandt brothers on the 10th of October 1892. It was initially distributed in France, then extensively in North America and Russia. In May 1914, the brand was transferred to SADA (Societe Anonyme Departement Achats), an organisation originally created by Omega in 1906 to supply inexpensive models to retailers who were not part of its official distribution network. These inexpensive brands included: Champ, Civic, Critic, Eagle, Ethic, Himalaya, Meric, and Valdez."Can you tell us where you got that information? I'm always leery of claims of obscure companies being connected to well known companies; it's the kind of trick that people use to try to pump up the price of the watch they're selling. And while there may be a connection, it may not be the connection you think. As near as I can tell, Patria was one of the brands that was imported by the U.S. company set up by Omega to faciliate sales in the U.S. in the 1920's. That matches the style and markings on your watch. But remember that the U.S. company is not the same as the Swiss company, even if they share parts of their name.
