The Etablissement Mixte series consisted of, according to Breguet himself, watches made outside his shop but to his design and under his supervision. The escapements, he claimed, were made in his shop.In the past, it had been assumed that this register was either lost or that it never existed, but this is not the case. Etablissement Mixte watches have their own special register, which is in the possession of the company. It begins with No. 1 in 1806 and continues to No. 2421 in 1832. All kinds of watches and clocks are recorded, some quite unusual. Since this Etablissement Mixte register is not numbered it is very difficult (but not impossible) to locate it in the book.Watches with a wandering hour dial first appeared in the 17th century.In the 1920's and 1930's, Breguet sold many wandering hour watches with a system patented in about 1925 by Robert Cart. More recently, the idea has enjoyed a revival, being introduced into the wristwatch.
