3629 “Bat” – Onyx Dial, 1970s - A Bold Design Icon with Mysterious Elegance
This rare Ref. 3629, nicknamed the “Bat” by collectors, is one of the most striking designs to emerge from the brand’s 1970s avant-garde period. With its sleek, angular silhouette, stepped case design, and a seamlessly integrated tubular bracelet, this reference exemplifies dramatic flair wrapped in timeless luxury.
But it’s the flawless black onyx stone dial — untouched and deep as midnight — that elevates this watch into another realm. Complemented by gold dauphine hands and a cabochon-cut onyx crown, it’s a true statement piece for the bold yet refined collector.
Powered by the slim rare — but supremely wearable and meticulously engineered.
A must-have for connoisseurs of hard stone dials, 1970s design, or simply the unexpected.
