Zenith "Zenittone" Jumbo Classic

The Zenith Jumbo Classic from 1968 stands as one of the most intriguing and elusive pieces ever linked to the brand. Produced during the collaborative era between Zenith and Movado, it embodies a remarkable fusion of Swiss innovation and mid-century refinement.

Its 41.5mm stainless steel case was extraordinary for its time — a bold size in an era when most watches rarely exceeded 38mm. The case, marked with the Movado/Zenith (MZ) hallmark, reveals the superb craftsmanship and balanced proportions that defined both manufacturers at their creative height.

At its heart beats the hand-wound Zenith Caliber 2532C, celebrated for its precision, reliability, and exceptionally smooth operation.

What truly enhances its allure is its extreme rarity. Only a handful of examples have ever surfaced among collectors or in the vintage market, and even Zenith’s own archives provide scarce information on this model. Its origins remain partly mysterious, suggesting it may have been produced in very limited numbers or as a special commission.

The blend of oversized proportions, elegant construction, and near-unknown production numbers make this piece one of the most captivating Zenith watches of its era — a forward-looking design that anticipated the larger cases and bold aesthetics that would come to define watchmaking decades later.
