Rolex Day-Date 40 40 mm 228398TBRWR Yellow Gold/Diamonds White Rolex Day-Date 40 40 mm 228398TBRWR Yellow…

The Rolex Day-Date is, by any measure, the most prestigious watch in the Rolex catalog. Introduced in 1956 as the first wristwatch to display the full spelling of the day of the week, it has been worn by heads of state, Nobel laureates, and cultural icons for nearly seven decades. The Day-Date 40 — launched as an evolution of the classic 36mm Day-Date — brings a larger 40mm case diameter to the lineage, expanding wrist presence without sacrificing the refined proportions that have always defined the model. Reference 228398TBRWR represents the absolute pinnacle of that tradition, pairing 18k yellow gold construction with a factory-set baguette diamond bezel and a white Roman numeral dial.

The case of the 228398TBRWR is crafted entirely in 18k yellow gold, Rolex's own proprietary alloy developed and refined in-house for depth of color and resistance to tarnish. At 40mm in diameter the case wears with commanding authority on the wrist while remaining elegant enough for a formal setting. The fluted profile of the lugs, the polished and brushed surfaces, and the domed sapphire crystal all speak to Rolex's obsessive commitment to finishing quality — every surface is hand-finished to standards that go far beyond what the eye can detect at a glance.

The bezel of the 228398TBRWR is set with baguette-cut diamonds in a continuous channel, one of the most labor-intensive and visually spectacular bezel configurations Rolex produces. Baguette diamonds, with their elongated rectangular geometry, must be individually matched for color and clarity and fitted by hand so that no metal is visible between stones — the result is an unbroken band of white light encircling the case. This factory diamond bezel is not an aftermarket modification; it is set by Rolex's own gem-setting specialists, which preserves the watch's authenticity and value in any future transaction.

The white dial is dressed with Roman numerals, a classic pairing that has graced Day-Date references since the model's earliest years. Roman numerals complement the yellow gold case by reinforcing the watch's formal, almost architectural character. At 12 o'clock the day display window shows the full name of the day in full-sized text, while the date window at 3 o'clock is framed by a Cyclops lens on the sapphire crystal for instant legibility. The President bracelet — developed specifically for the Day-Date and never fitted to another Rolex model — completes the ensemble with its three semi-circular links in solid 18k yellow gold, a hidden-clasp design, and a comfort fit that has made it the gold standard of luxury bracelets. The watch is powered by an automatic movement, water-resistant to 100 meters (330 feet).
