Datejust 31 Black MOP Diamond Dial Smooth Bezel Steel 18KT Yellow Gold Oyster 278243BKMDO

The Rolex Datejust 31 Reference 278243 (M278243BKMDO) is a striking and luxurious timepiece, defined by the rich interplay of black mother-of-pearl and yellow gold. It features a deep Black Mother-of-Pearl (MOP) dial with diamond markers, a sleek Smooth Bezel, and the robust Oyster bracelet, all within the versatile 31mm case size. This model is presented in the classic Rolesor Yellow Gold design (Oystersteel and 18K Yellow Gold).

It features a robust monobloc middle case in Oystersteel (Stainless Steel), complemented by a smooth, highly polished Domed (Smooth) Bezel crafted from radiant 18K Yellow Gold . The smooth bezel gives the watch a sleek, contemporary, and slightly more understated profile, drawing focus to the unique texture of the dial.

The timepiece is fitted with the robust, three-piece link Oyster bracelet, the sportier and more durable option in Rolex’s lineup. Crafted in a two-tone Rolesor Yellow Gold style, the outer links are in Oystersteel while the center links are in polished 18K Yellow Gold, creating a classic, harmonious contrast. It fastens securely with the folding Oysterclasp.

The centerpiece is the exotic Black Mother-of-Pearl Dial with Diamonds. This dial is naturally iridescent, shifting through deep, mysterious tones of black, grey, and deep blue depending on the light. Because MOP is a natural material, every dial is unique. The depth of the black MOP creates a spectacular contrast against the brilliant yellow gold.

The hours are marked by 11 brilliant-cut Diamond Hour Markers (with the Rolex Crown at 12 o’clock), meticulously set in 18K Yellow Gold. These diamonds enhance the dial’s natural luminescence and luxury, perfectly complementing the yellow gold bezel and bracelet accents.

Under the dial lies the robust and precise Calibre 2236 movement. This self-winding mechanical movement incorporates the patented Syloxi hairspring, providing exceptional performance, accuracy, and reliability, and is certified as a Superlative Chronometer, completing this highly distinguished timepiece.
