This is a luxury Rolex Ladies Datejust wristwatch, featuring a two-tone construction of Oystersteel and yellow gold. The watch is characterized by its 28mm or 31mm case size, outfitted with an 18k yellow gold fluted bezel and a signature Cyclops magnifying lens over the date window at the 3 o'clock position. The dial is a distinctive sunray-finished olive green, accented with high-quality diamond hour markers set in gold clous. The hands are fashioned from yellow gold to match the bezel and the center links of the five-piece Jubilee bracelet. The bracelet shows a mix of brushed steel outer links and polished gold center links, secured with a concealed folding Crownclasp. Physically, the watch appears in good vintage or pre-owned condition with light surface micro-abrasions consistent with regular wear, particularly on the polished gold surfaces. The craftsmanship represents Rolex's standard of chronometric precision and durability. The combination of the green dial and diamond markers indicates a more contemporary production era, likely from the late 2010s to early 2020s. No significant dents, deep scratches, or crystal chips are immediately visible in the provided image.

Upon visual inspection of this Rolex Datejust, I find it to be a high-demand contemporary reference, likely the 279173 (28mm). The sunray olive green dial paired with factory diamond hour markers is a highly sought-after configuration that currently commands a premium on the secondary market. The 'Rolesor' combination of 904L steel and 18k yellow gold appears consistent with Rolex’s manufacturing standards. The Jubilee bracelet shows minimal 'stretch,' and the fluted bezel retains sharp edges, suggesting the watch has not been over-polished. Market conditions for green-dial Rolex models remain strong, often trading near or slightly above original retail prices due to limited boutique availability. The presence of the concealed Crownclasp further reinforces its status as a modern luxury piece. However, a digital appraisal has inherent limitations. I cannot verify the movement's caliber, the serial number's authenticity against the registry, or the water resistance seals. To provide a definitive authentication, an in-person inspection by a certified horologist is required to examine the 'beat' of the movement, verify the presence of the laser-etched crown at the 6 o'clock position on the sapphire crystal, and cross-reference the original warranty card and box, which significantly influence the final valuation.
