Patek Philippe 3629 “Bat” – Onyx Dial, 1970s - A Bold Design Icon with Mysterious Elegance

This rare Patek Philippe 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 Patek Philippe Caliber 177, this manually wound timepiece is not only rare — but supremely wearable and meticulously engineered.

A must-have for connoisseurs of hard stone dials, 1970s design, or simply the unexpected.
