A classical expression of Breguet watchmaking, the Classique 5140BA distills the line's restrained elegance into a 40mm yellow gold case with a crisp white dial. Its proportions are notably balanced at 10.9mm thick, giving the watch a slim, composed profile on the wrist. An automatic movement suits the piece well, keeping the focus on everyday refinement rather than overt complication. In this configuration, it reads as pure Classique: formal, measured, and unmistakably Breguet.
