It inherits the iconic rounded case of the Ballon Bleu. At the 3 o'clock position, the “crown - protecting bridge + crown inlaid with a cabochon synthetic spinel” is a highly recognizable symbol of the brand; the curved sapphire crystal glass bulges like a balloon, fitting the wrist, with an inherent gentle luster and presenting a unique iridescence under light and shadow. Paired with classic Roman numeral hour markers, it blends retro and romance; the sword - shaped blued steel hands add a sense of refinement.
