At Perpetual Watch Lover, we’re proud to offer a standout vintage piece: the Rolex Oyster Precision Ref. 6424, a rare and highly desirable manual-wind Rolex from the mid-1960s. What sets this model apart is its uncommonly large 36mm case, earning it the nickname “Jumbo” among collectors.

While most Oyster Precision models from the era were produced in smaller 31mm to 34mm cases, the Ref. 6424 was manufactured in very limited numbers and only for a short production run, making it exceptionally rare on the market today. These larger-cased Precisions have developed a strong following, particularly among collectors who appreciate the classic lines of vintage Rolex combined with modern wrist presence.

This example features a clean silver/grey dial with applied baton markers and original dauphine hands—offering understated elegance and vintage authenticity. Powered by the hand-wound Rolex Calibre 1210, it delivers reliable, no-nonsense performance and has just undergone a complete professional service. The case remains in mint condition, and we proudly back the watch with a 2-year in-house warranty.

The Legacy of the Rolex Precision

The Rolex Precision line reflects a foundational era in Rolex's history—one defined by timeless aesthetics and robust engineering. Unlike the brand’s automatic offerings, Precision models were manual-winding, prized for their slim profiles and minimalist appeal. These were watches built to last, and their mechanical simplicity makes them especially appealing to purists.

Within this storied range, the Ref. 6424 is an outlier—sought after not only for its size but for its rarity. As collectors increasingly turn toward vintage pieces with distinct design traits and scarcity, the 6424 stands as one of the most coveted Precision references available today.
