Rolex, Oyster, Precision. Simple. Numerous variations of dials and movements were developed, but more often than not it was a series of 34mm cases equipped with automatic movements. Powered by the hand-wound caliber 1012. A movement that is compact, yet durable and reliable with 17 rubies and a double anti-shock system. Very cool surprise: the movement is nicely decorated by Rolex, which is quite rare for the crown brand that has always focused on performance rather than ornamentation.
A dial with soft cream patina, and a layout that reminds us of the model made in 1950, never released, and lent to New-Zealander Edmund Hillary for his expedition on Mount Everest in 1953. We all know this story’s happy ending.
Twelve faceted appliqué hour markers and a timer with 60 painted points share the dial. The Rolex crown sits majestically at the noon hour marker above the inscriptions “Rolex” and “Oyster.” The mention “Precision” and “T Swiss T”can be found below at 6 o’clock.
The most unique trait of the reference? Its size, clearly. While most Oyster Precisions, with or without date, appear with 34mm cases and an lug width of 18mm or 19mm, the reference 6424 proudly sports its 36mm and 20mm lug width. Yes, we were resembling dangerously close to the Explorer of the same period… Only that the extremely flat hand-wound mechanical movement used allows a very flat screwed-down case back. The result is no less than pure finesse. The brushed case with the polished bezel only adds to this Explorer feeling.
Another detail that will allow you to recognize a 6424 is that lugs that aren’t pierced. Rare for Rolex watches between the 1950’s and 1960’s since “un-pierced” lugs were mainly for cases made from precious metals.
With its large size and 20mm lug width, we have here a dressy watch with a military-adventurer feel about it. The bonus? This little beauty will go with any Submariner bracelet!
