The Rolex Day-Date 36 reference 128399TBR-0021 is a high-prestige timepiece crafted entirely from 18k white gold, featuring a 36mm Oyster case. This model is distinguished by its white dial with applied Roman numeral hour markers and a fixed bezel meticulously set with diamonds. The watch is paired with the iconic President bracelet, which consists of semi-circular three-piece links and a concealed folding Crownclasp, ensuring both comfort and a seamless aesthetic.
At its core, the timepiece is powered by the Rolex caliber 3255, a self-winding mechanical movement that is a certified Superlative Chronometer. This movement offers a power reserve of approximately 70 hours and features a paramagnetic blue Parachrom hairspring and high-performance Paraflex shock absorbers for enhanced durability. The complications include center hour, minute, and seconds hands, along with instantaneous day and date apertures that feature a secure rapid-setting function and stop-seconds for precise time adjustment.
General reviews of the 128399TBR emphasize its status as a definitive luxury watch that balances traditional elegance with contemporary watchmaking technology. The inclusion of the diamond-set bezel is frequently noted for adding a significant level of brilliance without compromising the classic silhouette of the Day-Date collection. While it is highly praised for its exceptional finishing and the reliability of the 3255 movement, some critics observe that its 36mm size and full white gold construction cater to a specific preference for traditional proportions and substantial weight. The watch remains a sought-after reference for collectors who value the historical significance of the “President’s watch” updated with modern gem-setting.
