Its gold dial, hand engine-turned and available in silvered or blue versions, subtly differentiates the reading zones through varied patterns: "panier maillé" for the power reserve, "damier" for the date and "clous de Paris" for the main part of the dial. Open-tipped Breguet hands and Roman numerals ensure easy readability in keeping with the House’s historic codes, while the extra-thin 502.3 caliber with a hand engine-turned gold rotor powers this 39 mm model.
