Rolex Day-Date 36 18ct Yellow Gold — Diamond-Set Bezel Champagne Diamond Dial | Ref. 128398TBR

Reference 128398TBR is the Day-Date 36 in 18ct yellow gold with a diamond-set bezel and a champagne dial set with diamonds—a configuration that places this watch at the intersection of horological excellence and high jewellery. The TBR suffix designates a bezel set with trapeze-cut diamonds, a more geometrically precise stone shape that creates a uniform, faceted band around the case rather than the rounded visual rhythm of brilliant cuts. The champagne diamond-set dial adds a second plane of gem presence, transforming the calendar display into an object of considerable material value.

Calibre 3255, present in this 2024 model, powers the Day-Date 36 with a 70-hour power reserve, Chronergy escapement, and Paraflex shock absorption. The movement is chronometer-certified across all positions and represents a meaningful advancement over the earlier 3155 calibre previously used in 36 mm Day-Date references. The yellow gold President bracelet—solid, semi-circular three-piece links machined entirely from 18ct gold—provides the bracelet architecture that has defined the Day-Date since its 1956 debut, worn here in the warmest tone Rolex produces.

With box and papers confirmed and a 2024 production year, this reference offers the reassurance of a near-new watch with full documentation and manufacturer warranty coverage. The trapeze-diamond bezel is a relatively recent Rolex innovation and adds a degree of rarity compared to standard brilliant-set bezels, appealing to collectors who seek differentiated configurations within the Day-Date family. At the premium end of the 36 mm Day-Date range, the 128398TBR represents an investment in both mechanical substance and demonstrable material value.
