Rolex Oyster Precision ‘Jumbo’ Ref. 6424 – Silver Dial – 36mm Case
Understated and unusually sized for its era, the Rolex Oyster Precision Ref. 6424 offers all the vintage charm of a 1960s Rolex — but with the rare jumbo 36mm case that sets it apart. While most manual-wind Precisions from this period were housed in 34mm cases, the Ref. 6424 delivers a noticeably larger wrist presence without compromising Rolex’s sleek, minimalist design.
This 1966 example features a crisp silver dial accented by sharp Alpha hands, giving it a refined, dressy aesthetic. With no date window to clutter the layout, it retains a clean, balanced design that feels just as relevant today as it did in the '60s. The dial is original and well-preserved, pairing beautifully with the warmth of the acrylic crystal above it.
Inside is the Rolex Calibre 1220 manual wind movement, known for its simplicity, reliability, and tactile winding experience — a delight for mechanical purists. It’s fitted with a grey suede strap that complements the silver tones and adds a touch of modern luxury.
