SIGNED ROLEX, OYSTER PERPETUAL, COSMOGRAPH DAYTONA "BIG RED" MODEL, REF. 6265, CASE NO. 6'197'324, CIRCA 1979

Introduced during the 1970s, the reference 6265 was manufactured until 1987 and is the sister reference of the 6263. With the main difference between both chronographs residing in the bezel, the 6265 was assembled with a stainless steel, 14 and 18K gold case as well as the mechanical Valjoux calibre 727 succeeding the calibre 722-1. Bearing the Oyster signature on its dial, the case featured more athletic proportions than previous references and benefited from enhanced waterproofness with screw-down chronograph pushers, a screw-down case back and a wider winding crown.
