AI Appraisal Estimate

This is a luxury Ladies Rolex Datejust, reference number 179161, featuring a distinctive 26mm case size. The timepiece is constructed from Rolex's proprietary 'Rolesor' combination of 904L stainless steel and 18k Everose gold. A standout feature is the unique bronze/champagne concentric circular guilloché dial, which displays applied rose gold Arabic numeral hour markers and a date aperture with a Cyclops magnification lens at the 3 o'clock position. The watch is fitted with a smooth dome-style Everose gold bezel and an Oyster-style bracelet consisting of brushed steel outer links and polished 18k Everose gold center links. Per the provided context, the item is in mint condition following a full professional overhaul by Rolex, which includes a service guarantee valid until August 2026. This example is highly collectible as it comes as a 'full set,' including the original presentation box, documentation, and the official service card. The craftsmanship is typical of the modern Rolex era, showcasing high-polish finishing, a scratch-resistant sapphire crystal, and an Oyster case designed for water resistance. There are no visible signs of wear, stretch in the bracelet, or scratches on the crystal, consistent with its professionally serviced status.

Based on my examination of the high-resolution documentation for this Ladies Rolex Datejust Ref. 179161, I have assessed its current market value. The combination of the 26mm Everose Rolesor construction and the rare bronze concentric guilloché dial makes this a highly desirable variant. Visual inspection confirms a 'mint' status; the case lugs maintain sharp factory chamfers, and the Oyster bracelet shows zero discernible 'stretch,' which is critical for value retention in discontinued 26mm models. The presence of a Rolex Service Center (RSC) card valid through 2026 is a significant value-add, as it serves as a tertiary layer of authentication for the internal Calibre 2235 movement and ensures mechanical integrity. In the current secondary market, 'Full Set' examples (box, papers, and service records) command a 15-20% premium over 'naked' watches. While the 26mm size is currently overshadowed by the 28mm and 31mm trends, the unique dial configuration maintains strong collector interest. Please note that while the serial numbers and finish align with authentic Rolex standards, this digital appraisal cannot definitively confirm the presence of every original internal component. To achieve a 100% authentication, an in-person diagnostic including a pressure test, movement timing analysis, and verification of the rehaut engraving and serial number matching against Rolex's database is required. Given the included RSC guarantee, the risk level for the buyer is exceptionally low, justifying the upper-tier valuation.
