Note: Shortly before his death in 1823, Breguet published a short pamphlet designed to explain his current production to the general public, under the title: Horlogerie pour I'Usage Civil, Chronomètres Portatifs, Horloges Marines et A s tr onomiques et Autres Instruments d'Observation, de Breguet et Fils, Horlogers de la Marine Royale de France. In this short work under article 13, he explained the term: Etablissement Mixte de Breguet, which appears on certain of the firm's watches: "The mixtes watches, either simple or repeating, are made outside our workshops, but to our design and under our supervision. The escapement and regulator (balance, balance spring, etc.) are finished by us". Unfortunately, the sales register recording these watches was lost or destroyed many years ago, and it is therefore not possible to give an accurate date of sale, price or the name of the buyer.
