The Rolex Datejust 31 Ref. 178383 is a radiant expression of feminine luxury, masterfully blending the enduring elegance of a two-tone design with the captivating brilliance of factory-set diamonds and a natural mother-of-pearl dial. This exquisite timepiece features a 31mm Oyster case, artfully constructed from a combination of corrosion-resistant stainless steel and warm 18K yellow gold, creating a versatile and lustrous foundation . The case is crowned by a fluted 18K yellow gold bezel that is meticulously set with a complete circuit of brilliant-cut diamonds, instantly elevating the watch with a sophisticated sparkle . The dial is a true work of natural art, crafted from genuine mother-of-pearl, whose iridescent surface shimmers with soft pinks, creams, and greens, creating a unique and luminous backdrop . This is complemented by diamond hour markers, which replace traditional indices for an added layer of opulence, and classic Roman numeral hour markers at the cardinal positions, harmonizing timeless tradition with high jewelry aesthetics . Powered by the reliable and precise automatic Caliber 2235, a COSC-certified chronometer, the watch offers a 48-hour power reserve and features a practical date window at 3 o’clock, magnified by the iconic Cyclops lens on the scratch-resistant sapphire crystal . The watch is completed by the legendary five-piece Jubilee bracelet, also in stainless steel and 18K yellow gold, which provides an exceptionally comfortable and elegant fit, secured by a concealed folding clasp . With its 100-meter water resistance, this Datejust 31 is as resilient as it is beautiful, making it the perfect heirloom-quality timepiece for the discerning client who seeks a seamless blend of iconic design, precious materials, and uncompromising Rolex craftsmanship . Key specifications: 31mm stainless steel and 18K yellow gold case; fluted 18K yellow gold diamond-set bezel; mother-of-pearl dial with diamond and Roman numeral hour markers; Caliber 2235 automatic movement; 48-hour power reserve; Jubilee bracelet; 100m water resistance; sapphire crystal with Cyclops lens .
