Rolex Day-Date 36 Yellow Gold — Champagne Diamond Baguette Dial | Ref. 128398TBR

Introduced in 2024, reference 128398TBR represents the Day-Date 36 at a level of gem-set complexity that few competitors can approach. The 36 mm case in 18-carat yellow gold carries a diamond-set bezel whose brilliant-cut stones encircle the dial in a continuous pavé ring, while the champagne dial is decorated with 10 baguette-cut diamonds deployed as hour indices — each stone individually set and precision-oriented by Rolex's manufacture lapidary team. The result is a dial in which geometry and gemology are held in studied equilibrium.

Calibre 3255 — powering the Day-Date 36 with the full suite of contemporary manufacture innovations — features the Chronergy escapement, developed across 14 patents covering escapement wheel geometry, lever profile, and lubricant-free operation. Energy efficiency improves by 15 percent over its predecessor, enabling a 70-hour power reserve that is among the most generous offered by any manufacture in this dress watch category. Certified as a Superlative Chronometer, each example is tested to deliver accuracy within +2/-2 seconds per day after casing.

Presented on the President bracelet in 18-carat yellow gold — the bracelet synonymous with the Day-Date since 1956 — this reference is secured by the concealed folding Crownclasp. Scratch-resistant sapphire crystal with Cyclops lens and water resistance to 100 metres complete the specification. Supplied with box and papers as a 2024 production piece, this baguette-set Day-Date represents both immediate wearability and long-term collectibility as Rolex's most gemologically sophisticated President references grow scarcer in the secondary market.
