Vacheron Constantin Ref. 2099 – Onyx & Diamond Masterpiece in White Gold
Here we have one of the rarest — possibly unique — Vacheron Constantin pieces we have ever encountered. Crafted in 18k white gold, the sharply preserved 30 mm case is paired with an integrated basket-weave white gold bracelet, giving the watch extraordinary texture and presence.
The true highlight is the flawless deep black onyx dial, framed by a stunning diamond-set bezel (40 diamonds) — a configuration we have never seen before in this reference.
Powered by the ultra-thin Vacheron Constantin Cal. 1003, this near-NOS example blends haute horlogerie with high jewelry in a way only Vacheron can — bold, rare, and undeniably exceptional.
