Rolex ref 1013, Glossy black dial

The Rolex Oyster Perpetual reference 1013 in 18kt yellow gold with a glossy black dial is a timepiece of extraordinary rarity and is considered by collectors to be the most coveted variant in the entire production history of this model. Reference 1013 is distinguished as the "oversize" version of the Oyster Perpetual because it adopted a 36mm case—the same iconic dimensions as the Datejust and Day-Date of the period—at a time when the standard model measured only 34mm. While the steel version is rare in its own right, the reference 1013 in solid 18kt yellow gold is an absolute exception, as very few examples were produced and even fewer have survived in such pristine, original condition. The heart of this watch is the deep glossy black dial, which features a "No-Date" configuration that ensures perfect symmetry and heightens the purity of the overall design. Its mirror-like surface creates a magnetic contrast with the applied gold baton indices and gilt dauphine hands, while the double line "Superlative Chronometer Officially Certified" beneath the Rolex crown at 12 o'clock attests to its COSC certification. Furthermore, the "T SWISS T" signature at the bottom of the dial unequivocally dates the watch to the period of tritium luminescent materials typical of the late 1950s and early 1960s. The aesthetic excellence extends to the Oyster case, which is characterized by the celebrated fluted bezel in yellow gold. The unmistakable grooved workmanship of the bezel catches the light with warm, sharp reflections, complementing the elegantly curved lugs that represent the pinnacle of formal simplicity. Internally, the watch is powered by the Caliber 1560, the legendary "workhorse" automatic movement of the era that is regarded as one of the most successful and enduring mechanical hearts in Rolex history.
