Vintage 1973 Rolex Daytona reference 6263, notable for its steel case, original MK II screw-down pushers, and a highly sought-after black acrylic bezel paired with a rare black Sigma dial—characteristic of early, pre-'big red' Daytona models. It is powered by the manually-wound Valjoux caliber 727 movement. Black bezel versions of the 6263 are described as much harder to find than the steel bezel 6265, with black dials being especially rare among vintage Daytonas.
The second paragraph focuses on the watch’s monochrome Sigma dial, which features the “Rolex Oyster Cosmograph” text in a serifed silver typeface, and the ‘σ T Swiss T σ’ marking at 6 o’clock, indicating the use of precious metal. The hands are made of white gold and filled with tritium, as are the baton hour markers tipped with small tritium spheres. The chronograph’s silver concentric registers provide contrast against the matte black dial.
