The Day-Date 36 also introduces an outstanding dial design with faceted, deconstructed Roman numerals and index hour markers. The new 18K yellow gold variant features a white lacquer dial, enhanced by these emblematic hour markers known for their flawless geometric shapes and smooth, shiny finish. Each element undergoes no fewer than seven operations by Rolex experts before being applied to the dial.
Lastly, the Day-Date 36 in 18k Everose gold welcomes a spectacular blue-green dial – a colour first seen on the Oyster Perpetual Sky-Dweller in 2023. Embellished with 10 baguette-cut diamonds, the dial is framed by a bezel set with 60 trapeze-cut diamonds. Crafting this bezel requires scrupulous attention and patience, with each stone individually adjusted and set by hand by professional gem-setters.
TECHNICAL EXCELLENCE: CALIBRE 3255
The Day-Date 40 and Day-Date 36 house the calibre 3255, a self-winding mechanical movement known for its precision, convenience, reliability and a power reserve of about 70 hours.
At the heart of the calibre 3255 is the patented Chronergy escapement, which balances high energy efficiency with exceptional dependability. Crafted from nickel-phosphorus, this escapement is resistant to strong magnetic fields.
The movement also features a blue Parachrom hairspring, made from a paramagnetic alloy developed by Rolex. This innovative hairspring offers remarkable stability against temperature variations and superior shock resistance, further enhanced by the Rolex overcoil. The oscillator is mounted on Rolex-designed, patented high-performance Paraflex shock absorbers, which boost the movement’s shock resistance. Since 2023, the oscillating weight has been upgraded with an optimised ball bearing for even smoother operation.
ULTIMATE REFINEMENT
The Day-Date 40 and Day-Date 36 are elegantly paired with the iconic President bracelet. First introduced in 1956 alongside the original Oyster Perpetual Day-Date, this bracelet features semi-circular three-piece links crafted from 18K gold or 950 platinum and is reserved solely for the Day-Date and select precious metal versions of the Datejust.
