Rolex Oyster Precision Ref. 6424 steel vintage wristwatch, circa 1966
A large sized stainless steel manually wound centre seconds wristwatch with Rolex Oyster bracelet
Measuring 36mm in diameter, this is one of the largest of the vintage, time only, Rolex Oyster models. The handsome silvered dial has multi-faceted tapered indexes with broader, twin tapered indexes at 3, 6 and 9 o’clock. Reference 6424 is similarly styled to the Ref. 6426, however, the 6424 is considerably rarer and has a number of distinctive features. First, in size terms, not only does the 6424 have a large case diameter of 36mm, but the overall length (including lugs) measures 43mm, this compares to the 41.5mm of the 6426 reference. Unlike the ref. 6426, the 6424’s lugs are un-pierced to the outside of the case, leaving an unbroken sweep to the polished case sides and are designed to take a 20mm wide strap or bracelet. The larger case back of the 6424 is also shaped differently with a central satin finished circle surrounded by a broad, polished chamfer – this compares to the flat polished back of the 6426. This watch is fitted with a Rolex model 78360 heavy gauge Oyster link bracelet with adjustable folding clasp and removable, screw-set links – there is slight stretch to the links from wear.
As part of this watch’s service and overhaul it has been pressure tested for water resistance for depths up to 100 metres. Prior to the servicing we have recently had carried out on this watch, the watch was overhauled by Rolex in 2012 and is accompanied by the numbered service card of that date.
