Rolex Day-Date 36 Gold — Green Aventurine Dial | Ref. 128345RBR

Reference 128345RBR presents the Day-Date 36 in one of its most captivating natural material dials — green aventurine, a gemstone prized for its shimmering metallic inclusions that create an almost galactic depth within the dial surface. No two aventurine dials are alike; the distribution of fuchsite inclusions is entirely natural, rendering each example genuinely one-of-a-kind. Set within a gold Oyster case and complemented by the RBR diamond-set bezel, this Day-Date 36 achieves an interplay between geological wonder and horological precision that few timepieces can claim.

The 128xxx series Day-Date 36 is powered by the Calibre 3255, Rolex's benchmark self-winding manufacture movement. The 3255 incorporates the Chronergy escapement — a patented lever mechanism in nickel-phosphorus delivering 15 percent greater energy efficiency — alongside the Parachrom hairspring, which in Rolex's proprietary paramagnetic alloy provides tenfold resilience against magnetic fields compared to conventional hairsprings. A 70-hour power reserve and Superlative Chronometer certification to ±2 seconds per day complete the technical profile. The President bracelet, available in matching gold, provides the characteristic comfort and elegance that has defined the Day-Date since its debut in 1956.

Aventurine dials represent Rolex's most coveted natural material dial series — a category that also includes meteorite, malachite and onyx — and green aventurine has attracted particular collector attention owing to the resurgent global demand for anything green-dialled. The combination with a diamond bezel (RBR) and gold case creates a watch of genuine rarity and jewellery-grade specification. For collectors seeking a Day-Date that functions simultaneously as a horological artefact and a natural mineral showcase, reference 128345RBR is an extraordinary and enduring choice.
