Rolex Day-Date 40 Yellow Gold — Silver Diagonal Motif Dial | Ref. 228348RBR

Reference 228348RBR is one of the flagship configurations of the Day-Date 40, Rolex's largest and most architecturally bold presidential watch. Launched in 2015 to replace the Day-Date II (218xxx), the 228xxx generation refined the case profile while retaining the 40 mm footprint that positions it firmly as a power-dressing executive instrument. The silver diagonal motif dial with applied index markers in 18ct yellow gold provides a textured surface that shifts under directional light, adding visual depth without resorting to colour.

Calibre 3255 — Rolex's most advanced self-winding movement to date — powers this reference. Its Chronergy escapement, combining a horizontal-tooth lever with a redesigned escape wheel geometry, delivers 70 hours of power reserve and improved shock resistance. The movement is certified as a Superlative Chronometer to ±2 seconds per day after casing. The 40 mm case is rendered entirely in 18ct yellow gold with a diamond-set bezel indicated by the RBR suffix, and is paired with the President bracelet — a three-link construction in solid yellow gold available only on Day-Date references.

Collectors targeting the Day-Date 40 in solid gold with a diamond bezel are entering one of the most liquid segments of the modern Rolex market. The 228xxx generation's improved movement and refined case have helped it overtake the prior 218xxx generation in collector preference. Silver dial variants are understated by Day-Date standards, offering broad wearability while retaining the prestige of the full precious-metal specification.
