The Rolex Lady-Datejust reference 279173-0019 is a 28mm luxury timepiece featuring a Yellow Rolesor construction, which harmoniously combines durable Oystersteel with 18k yellow gold. This model is distinguished by its sunray-finished silver dial adorned with 18k gold index hour markers and the iconic fluted bezel, a signature Rolex aesthetic. The watch is equipped with the supple five-piece link Jubilee bracelet, secured by a concealed folding Crownclasp. Its Oyster case, featuring a screw-down Twinlock crown and scratch-resistant sapphire crystal with a Cyclops lens, ensures water resistance up to 100 meters.
Powered by the self-winding caliber 2236, the watch offers a power reserve of approximately 55 hours and maintains a precision of -2/+2 seconds per day. The movement includes high-performance Paraflex shock absorbers and a patented Syloxi hairspring in silicon, which provides exceptional resistance to magnetic fields and temperature variations. Its primary complications include center hour, minute, and seconds hands, along with an instantaneous date window at the 3 o’clock position and stop-seconds for precise time setting.
General reviews of the 279173-0019 frequently praise its balanced proportions and the refined transition from the classic 26mm to the contemporary 28mm case size. It is widely regarded as an ideal everyday watch due to its versatile two-tone design and robust build quality. While enthusiasts appreciate the accuracy and reliability of the manufacture movement, some minor criticisms note that the polished center links of the yellow gold sections are prone to fine scratches, though the Jubilee bracelet is often cited for its ability to mask these signs of wear effectively.
