Manufactured in the mid-1960s, this International timepiece is a rare Ref. 648A Jumbo Waterproof model with a unique silver dial, and it comes with its original bracelet. Unlike the typical sizes of around 35mm seen in non-sport models of that era, this International watch boasts a rare oversized 36mm waterproof case for the period. It is equipped with their in-house Caliber 853 movement.

The dial design is also exceptional, featuring large applied indices paired with dauphine hands, creating a distinctive design on the silver dial. This unique dial, combined with the jumbo-sized case, creates a remarkable presence that evokes the sense of a 38mm size. The original bracelet is included, suitable for a wrist circumference of up to 17.5cm.
