Rolex Datejust 31 – Ref. 278384RBR-0038

The Rolex Datejust 31 Ref. 278384RBR-0038 is a stunning women’s timepiece that masterfully merges jewellery brilliance with Rolex’s precision engineering. Crafted in White Rolesor (a blend of Oystersteel and 18k white gold), it features a diamond-set bezel, a bright blue sunray dial with applied Roman numerals, and the robust Calibre 2236 movement. Designed for elegance, durability, and readability, this 31 mm model commands attention while maintaining timeless sophistication.

Case, Materials & Bezel

The 31 mm Oyster case is constructed from Oystersteel and accented with an 18k white gold diamond-set bezel. The bezel is adorned with brilliant white diamonds, gem-set by Rolex’s master craftsmen for uniform sparkle and precision. The case features a screw-down Twinlock crown and a solid case back, delivering 100 meters / 330 feet of water resistance. Combined with scratch-resistant sapphire crystal and Rolex’s signature Cyclops lens over the date, it balances luxury with function.

Dial & Markers

What truly distinguishes Ref. 278384RBR-0038 is its radiant bright blue sunray dial, finished using Rolex’s sunray brushing technique to produce dynamic reflections as the wrist moves. The dial is paired with applied Roman numeral hour markers in white gold, adding a classical touch to the contemporary blue hue. Polished white-gold hands provide clarity and elegant contrast. The date window at 3 o’clock benefits from the Cyclops magnifier for onsite ease of reading.

Movement & Performance

Inside lives the Rolex Calibre 2236, an automatic self-winding movement enriched with modern features like the Syloxi silicon hairspring and Paraflex shock absorbers, enhancing both precision and resilience. Certified as a Superlative Chronometer after casing, the watch maintains a tight tolerance of −2/+2 seconds per day. It offers approximately 55 hours of power reserve, making it reliable for both daily wear and occasional rotation.

Bracelet & Comfort Features

The 278384rbr-0038 is equipped with the robust Oyster bracelet, composed of three-piece solid links for strength and refined polish. Secured with a folding Oysterclasp featuring Easylink 5 mm comfort extension, it allows for minor adjustments on the go without tools. The bracelet’s design ensures comfort, elegance, and durability, harmonizing with the case’s proportions and finish.
