Rolex Datejust 31mm Mint Green on Oyster 278240 2021 [Preowned]

Overview 

The Rolex Datejust 31 reference 278240 is a sophisticated mid-size expression of the world’s most iconic date-displaying chronometer. Perfectly proportioned for those who find the 28mm too petite and the 36mm too commanding, the 31mm case strikes an ideal balance of elegance and presence. Crafted entirely from Oystersteel—Rolex’s proprietary 904L alloy—this model represents the intersection of high-jewelry aesthetics and the rugged durability of a professional tool watch.

The defining characteristic of this reference is the Mint Green dial, a contemporary hue that has become one of the most coveted colors in the modern Rolex catalog. The sunray finish allows the dial to shift in tone from a soft, pastel sage to a vibrant metallic emerald depending on the light. Framed by a polished smooth bezel, the watch maintains a sleek, minimalist silhouette that emphasizes the dial’s clarity. The 18k white gold baton indices are filled with Chromalight luminescence, ensuring the watch remains highly legible in all lighting conditions while resisting tarnish over decades of wear.

In this configuration, the watch is paired with the three-link Oyster bracelet, providing a sportier and more industrial feel compared to the ornate Jubilee. The Oyster bracelet is celebrated for its structural integrity and secure fit, making it the perfect choice for an active lifestyle. It features the Oysterclasp and the Easylink 5mm comfort extension, a practical engineering feat that allows the wearer to increase the bracelet length instantaneously—a welcome feature as the wrist expands in warmer weather.

Beneath the surface, the 278240 is powered by the Manufacture Calibre 2236, a self-winding mechanical movement at the forefront of watchmaking technology. It features Rolex’s patented Syloxi hairspring in silicon, which is more precise than a traditional hairspring when subjected to shocks and remains completely unaffected by magnetic fields. With a 55-hour power reserve and a Superlative Chronometer certification, this Datejust 31 is a high-precision instrument that delivers 100 meters of water resistance, making it a dependable, stylish companion for any occasion.
