Housed in a round 44mm case of 18K 5N pink gold — extending to the bezel, crown, and deployant buckle — the Traditionnelle 80172/000R-B406 presents a refined profile at 13.54mm thick. The transparent sapphire caseback opens a view to the movement within, while the metal dial faces outward with understated elegance.
A black alligator Mississippiensis strap secures the watch to the wrist, fastened by a deployant buckle in matching 18K 5N pink gold. The combination of supple strap and warm rose gold hardware gives the piece a cohesive, considered character.
Combining a tourbillon with a perpetual calendar, this reference sits at the upper register of the Traditionnelle collection — a pairing that reflects the depth of complication Vacheron Constantin places within the classic round case form.
