The Rolex Datejust 31 reference 278275-0037 is a luxury timepiece crafted entirely from 18k Everose gold, a proprietary pink gold alloy developed by Rolex to ensure long-lasting luster. This model features a 31mm Oyster case equipped with a signature fluted bezel and a scratch-resistant sapphire crystal with a Cyclops lens for date magnification. The rose-colored dial is finished with a sunray pattern that creates subtle light reflections and is adorned with index hour markers. It is paired with the prestigious President bracelet, characterized by its semi-circular three-piece links and a concealed folding Crownclasp.
The watch is powered by the in-house caliber 2236, a self-winding mechanical movement that is a COSC-certified chronometer. This movement incorporates a Syloxi hairspring in silicon and high-performance Paraflex shock absorbers, providing a power reserve of approximately 55 hours and a precision of -2/+2 seconds per day. Its complications include central hour, minute, and seconds hands, along with an instantaneous date display at the 3 o’clock position featuring rapid setting. The Twinlock screw-down crown and solid case back contribute to a water resistance rating of 100 meters.
General reviews of the Datejust 31 series emphasize its classic aesthetic and the refinement of its mid-size proportions, which offer a balanced presence on the wrist. The 278275 model is frequently praised for the seamless integration of its Everose gold construction with the iconic President bracelet, a combination often reserved for Rolex’s most prestigious lines. While it is highly regarded for its mechanical reliability and timeless design, some enthusiasts note that its full gold construction and high-end positioning make it a significant investment compared to stainless steel or Rolesor alternatives.
