Rolex Day-Date 40 Platinum — Blue Bevelled Roman Dial | Ref. 228396TBR

Reference 228396TBR stands at the absolute apex of the Rolex catalogue. Constructed entirely in platinum — the rarest and densest precious metal used by Rolex — the Day-Date 40 in this configuration is reserved for those who seek the marque's most uncompromising statement. The 'TBR' suffix denotes a baguette-cut diamond or gemstone bezel, here set with alternating stones in a channel that encircles the 40 mm Oyster case in an unbroken band of light. The blue bevelled Roman numeral dial, crafted in lacquer with sharp bevelled chapter markers, delivers legibility through deliberate classical proportions.

Calibre 3255 drives this reference — Rolex's most technically advanced self-winding movement, introduced in the Day-Date 40 generation. It features a Chronergy escapement with a nickel-phosphorus lever and escape wheel, a paramagnetic Parachrom hairspring, and delivers 70 hours of power reserve with exceptional accuracy tolerances. The platinum President bracelet — exclusively fitted to Day-Date models in platinum or gold — with its semi-circular three-piece links, is machined to the same standard as the case itself.

In collector terms, platinum Day-Date 40 references with baguette bezels are among the lowest-volume production pieces in the entire Rolex range. Platinum's relative scarcity in the Rolex lineup — confined almost entirely to the Day-Date — combined with a complex gem-setting process means these references command significant premiums above their already substantial retail prices. The 228396TBR appeals to the serious collector for whom the Day-Date represents the definitive presidential timepiece.
