One of the earliest pieces produced under the historic Breguet name, the design and movement of the ref. 3450 were developed by Daniel Roth, whilst he was Master Watchmaker at Breguet, working closely with the Lemania movement manufacturer. Years later, Roth would use the same ébauche in the tourbillons he produced under his own name, as an independent watchmaker. With a two-tone combination of platinum and rose gold, this piece is an intriguing example of Roth's early work.
