Rolex Datejust 18k Yellow Gold: the black-dial chronometer watch with fluted bezel

This Rolex watch is an Oyster Perpetual Datejust, reference 6827, in solid 18-carat yellow gold, in its midsize 31mm format. Dated 1979, it belongs to one of the most emblematic lineages in watchmaking: the Datejust, born in 1945, the first self-winding wristwatch to display the date in an aperture. Unisex, it suits both a man and a woman. Its gold Oyster case, with screw-down crown and case back, is framed by the famous Rolex fluted bezel. It measures 31mm (33.4mm with the crown) for a Lug-to-lug of 36.5mm.

The deep black dial is of understated, timeless elegance. Applied gilt baton hour markers, topped with a luminous dot, rhythm the outer ring beneath the Rolex crown, the OYSTER PERPETUAL DATEJUST signatures and the SUPERLATIVE CHRONOMETER OFFICIALLY CERTIFIED mention. The “T Swiss Made T” mention at the bottom of the dial attests to the use of tritium, a hallmark of Rolex watches from this era. The date window at 3 o’clock is topped by the characteristic cyclops magnifier. The gilt hands with luminous inserts complete the ensemble.

At its heart beats the Rolex caliber 2030, a manufacture automatic movement with 28 jewels, a COSC-certified chronometer. It is one of the first quickset Rolex date movements, offering approximately 42 hours of power reserve and renowned for its robustness. The movement of this example has been serviced by our watchmaker.

On the wrist, the piece quietly asserts the status of the Datejust: that of a universal dress watch, worn across generations and on any occasion. Solid yellow gold, the black dial and the fluted bezel compose an ensemble of striking presence, here enhanced by a black crocodile-style leather strap, secured by an original 18k yellow gold Rolex Buckle. The Lug width of 17mm leaves the choice of replacement straps open.

Three points to note

  • The case, crown and Buckle are in solid 18-carat yellow gold: this is an all-gold Rolex, not a two-tone or plated version.
  • The black dial with baton hour markers is an original Rolex dial, without diamonds: a sober and highly sought-after configuration for this reference.
  • The caliber 2030 is a COSC-certified quickset chronometer: a manufacture movement renowned for its reliability, here serviced and guaranteed.
