A luxurious Rolex Oyster Perpetual Day-Date 40 in 18K yellow gold, featuring a rare black marble dial with natural veining and baguette-cut diamond hour markers.

Powered by the Caliber 3255 automatic movement—Superlative Chronometer certified to ±2 sec/day—the watch offers exceptional precision and reliability. The day aperture at 12 o’clock shows 'SUNDAY' in white on a silver plaque, enhancing its executive elegance. Crafted entirely in solid yellow gold with a scratch-resistant sapphire crystal, this timepiece combines horological excellence with bold aesthetic distinction. Ideal for formal events, boardroom meetings, or as a legacy investment piece, it exudes timeless sophistication and status. The marble dial variant is a limited-production specialty, highly sought after by collectors for its unique organic texture against the polished gold case and bracelet.
