The Rolex Datejust 36 Ref. 126231 is a refined expression of modern luxury, presented in an elegant Rolesor construction that masterfully blends robust Oystersteel with warm 18K Everose gold . This 36mm timepiece features a fluted 18K Everose gold bezel and a chocolate sunray dial, whose rich, deep brown hue is a result of meticulous brushing techniques that create a subtle, characteristic glow that shifts with the light . At its heart beats the advanced in-house automatic Caliber 3235, a Superlative Chronometer-certified movement that delivers an impressive 70-hour power reserve, the patented Chronergy escapement for superior efficiency, and a blue Parachrom hairspring for exceptional shock and magnetic resistance . The watch is secured by the robust and comfortable Oyster bracelet, crafted from Oystersteel and 18K Everose gold, which features an Oysterclasp and the Easylink 5mm comfort extension link for quick, tool-free adjustment to ensure a perfect fit in any climate . With 100 metres of water resistance, a screw‑down Twinlock crown, and a scratch-resistant sapphire crystal with a Cyclops lens over the date, this Datejust 36 is supremely durable and effortlessly transitions from formal occasions to everyday wear, offering the discerning collector a seamless blend of Rolex’s timeless prestige and the enduring reliability of cutting-edge Swiss watchmaking . Key specifications: 36mm Oystersteel and 18K Everose gold case; fluted Everose gold bezel; chocolate sunray dial; Rolex Caliber 3235 automatic movement; 70-hour power reserve; Oyster bracelet with Easylink; 100m water resistance; sapphire crystal with Cyclops.
