Rolex Day-Date 40 Yellow Gold — White Bevelled Roman Dial | Ref. 228398TBR

Reference 228398TBR stands among the most extraordinary expressions of the Rolex Day-Date 40 — a baguette diamond-set bezel adorning the 40 mm yellow gold Oyster case, paired with a white dial featuring bevelled Roman numeral hour markers. The TBR suffix denotes the scattered baguette-cut diamonds that line the bezel channel, each stone individually selected for colour and clarity, creating a continuous band of angular brilliance that captures light with exceptional intensity.

At its heart beats the Calibre 3255, arguably Rolex's most technically advanced self-winding movement. Developed over a decade and introduced in 2015, the 3255 incorporates 14 proprietary patents, including the Chronergy escapement — a nickel-phosphorus lever-and-escape wheel system that improves energy efficiency by 15 percent — alongside a Parachrom hairspring immune to magnetic fields and a 70-hour power reserve. The movement delivers ±2 seconds per day, a standard that surpasses COSC requirements by a significant margin.

The 228398TBR is quintessentially the President's watch — the Day-Date has been worn by heads of state, Nobel laureates, and cultural icons since its 1956 debut, and the baguette bezel variant represents the pinnacle of that tradition. In yellow gold with a white Roman dial, the combination reads as formal and commanding. For serious collectors, TBR-suffix Day-Date 40 references command significant premiums on the secondary market, with baguette-set bezels representing one of the most labour-intensive and costly Rolex factory configurations available.
