The Rolex Lady Datejust in this 179173NGE configuration represents a specific evolution within the longstanding Datejust collection, known for its consistent design language since its 1945 introduction. This particular model utilizes a 26mm Oyster case construction that combines a polished steel middle case with an 18k yellow gold fluted bezel, a signature Rolex design element. The bracelet is the five-piece link Jubilee, also executed in stainless steel and 18k yellow gold, providing a comfortable and secure fit. The dial is a white mother-of-pearl surface, selected for its unique, iridescent quality, and is set with diamond hour markers alongside applied 18k yellow gold Roman numerals at the 6 and 9 o’clock positions. This specific variant is further distinguished by its use of emerald-set hour markers, a feature that elevates its exclusivity within the Lady Datejust range.
At the core of this timepiece is the Caliber 2235, a self-winding mechanical movement that is a COSC-certified chronometer. This certification process ensures the movement meets strict precision standards. The complication is the eponymous date function, displayed at the 3 o’clock position through a Cyclops lens magnified 2.5 times, a hallmark of the Datejust line. The movement also features a paramagnetic blue Parachrom hairspring, which offers increased resistance to shocks and magnetic fields, contributing to its long-term reliability. The case provides 100 meters of water resistance due to the hermetically sealed Rolex Oyster architecture, secured by a Twinlock winding crown.
This specific watch is in mint condition, indicating it shows no visible signs of prior wear on its case, bezel, bracelet, or crystal. It is accompanied by its official Rolex warranty card, which is a critical document for authentication and future service. The combination of its mint state, complete documentation, and the specific configuration with a white mother-of-pearl dial and emerald markers makes this a particularly collectible example. The use of emeralds, as opposed to the more common diamond markers, creates a rarer and more sought-after variant. This positions the watch favorably in the secondary market, as its condition and unique feature set appeal to collectors seeking a well-preserved and distinctive model from the Lady Datejust lineup.
