The Rolex Day-Date 36 reference 128399TBR-0007 is a prestigious 36mm dress watch crafted from 18kt white gold. This model is distinguished by its blue ombré dial, which features a sunray finish that transitions from a vibrant blue center to a deep black perimeter. The dial is further elevated by diamond hour markers, including baguette-cut diamonds at the 6 and 9 o’clock positions. Complementing the dial is a fixed bezel meticulously set with brilliant-cut diamonds, housed in a white gold Oyster case with a screw-down crown and a scratch-resistant sapphire crystal featuring a Cyclops lens for date magnification.
The timepiece is powered by the in-house Calibre 3255, a self-winding mechanical movement that is a COSC-certified Superlative Chronometer. It offers a substantial power reserve of approximately 70 hours and features a paramagnetic blue Parachrom hairspring for increased resistance to shocks and temperature variations. The primary complications include the signature instantaneous day and date displays in apertures on the dial, along with central hours, minutes, and seconds. The watch is waterproof to a depth of 100 meters and is fitted with the iconic white gold President bracelet, known for its semi-circular three-piece links and concealed folding Crownclasp.
General reviews of this reference emphasize its striking aesthetic balance, often describing the blue ombré dial as one of the most captivating modern designs in the Day-Date collection. Enthusiasts appreciate the 36mm case size for its classic proportions and suitability for a wide range of wrist sizes, while the white gold construction offers a discreet yet weighty luxury feel. While some collectors note that the diamond-set bezel and dial make it a more decorative “jewelry” piece than standard configurations, it is highly regarded for its exceptional finishing and the reliable performance of the updated 3255 movement.
