Rolex Day-Date 36 Yellow Gold — Turquoise Diamond Roman Dial | Ref. 128348RBR

Reference 128348RBR is a Day-Date 36 that carries the full weight of the model's presidential heritage while deploying one of the most visually arresting dial treatments in the current range. Turquoise dials in the Day-Date lineage have a documented history, appearing in various forms across decades of production, but the current generation's turquoise with diamond Roman numerals represents the most refined iteration yet. Yellow gold with a diamond RBR bezel amplifies the chromatic contrast between the warm case metal and the cool blue-green of the natural stone dial.

The movement is Calibre 3255, Rolex's flagship self-winding calibre introduced in 2015. It represents a comprehensive engineering advance over its predecessors, incorporating the Chronergy escapement — co-developed with the Parachrom hairspring's successors — and delivering 70 hours of power reserve with accuracy certified to -2/+2 seconds per day. The Day-Date 36's president bracelet in 18ct yellow gold is the original and definitive bracelet for this reference, worn by heads of state and significant figures since the model's introduction in 1956.

The turquoise dial Day-Date commands serious collector attention. Semi-precious stone dials — turquoise, malachite, meteorite, onyx — are among the most desirable configurations in the Day-Date range and have historically appreciated strongly. The 128348RBR with diamond bezel and Roman numerals is a considered combination: the diamond bezel and turquoise dial reinforce each other visually, and the Roman numerals suit the formal register of the model. Buyers should verify stone dial authenticity carefully and expect to pay a meaningful premium above list on the secondary market for well-preserved examples.
