Rolex Lady-Datejust Yellow Rolesor — Silver Diamond Dial | Ref. 279173

Reference 279173 represents the Lady-Datejust 28 in Yellow Rolesor — Oystersteel paired with 18ct yellow gold — configured here with a fluted gold bezel and a silver dial set with diamond hour markers. Introduced in 2016 as a replacement for the 179173, the 279xxx generation brought a subtly refined case profile and the upgraded Calibre 2236 movement, making it the definitive modern expression of Rolex's entry-level precious-metal ladies' sports-dress watch.

Calibre 2236 is a movement built specifically for the Lady-Datejust and Datejust 31 families. Its Syloxi silicon hairspring, designed and produced entirely in-house, offers superior resistance to magnetic interference and eliminates the need for a Faraday cage. The 28 mm Oyster case provides 100 metres of water resistance despite the elegant proportions, and the fluted bezel — machined from solid 18ct yellow gold — serves both ornamental and structural roles. The Jubilee bracelet in Rolesor configuration matches the case metals for a cohesive aesthetic.

Silver diamond dials on the Lady-Datejust 28 remain perennially popular because they complement virtually every context from business to black-tie. The 279173 in Rolesor is widely available on the secondary market, which keeps entry prices competitive, but examples retaining original bracelet links and unworn condition command meaningful premiums. It is a sensible first Rolex for discerning buyers who value longevity of design over novelty.
