Crafted entirely in platinum 950 — case, bezel, crown, and deployant buckle alike — the Traditionnelle 80172/000P-9505 presents a round 44mm profile measuring 13.54mm thick. The metal dial sits behind sapphire crystal, while a transparent caseback offers a direct view of the movement within.
At the heart of this timepiece lie two of haute horlogerie's most demanding complications: a perpetual calendar and a tourbillon. The combination reflects the depth of craft that defines the Traditionnelle collection, housed in a case where every component shares the same platinum 950 specification.
A black alligator Mississippiensis strap with a platinum 950 deployant buckle completes the configuration, pairing supple texture with the cool weight of the case metal for a cohesive and considered wrist presence.
