The movement is not functioning properly, and the repeating mechanism strikes incorrectly. The first dial has chips around the winding hole and at 5 o’clock, while the second dial shows visible damage around the edge and chips next to the hands. The year, month, and date indications have tarnished, making them difficult to read. Additionally, the case has scuff marks and slight chips to the enamel decorations. A French control mark is also present on the stem.

In his book, “Dictionnaire des Horlogers Français,” Tardy notes that Jean-Pierre Tavernier became a Master in 1746 and was recorded at the Rue de Bucy, Paris, in 1748. Tavernier passed away at the age of 81 in 1796. Tavernier’s son Louis (1754–1840) is known to have produced similar double dial watches to his father. Louis became a Master in 1788 and was appointed as Horloger to the Duc d’Orléans in 1790. A similar double dial watch by Tavernier numbered 1111, can be found at the Patek Philippe Museum in Geneva.
