About the Rolex Lady-Datejust 279178

The Rolex Lady-Datejust 279178 is the current-production 28mm Lady-Datejust crafted entirely in solid 18k yellow gold, with a fluted yellow gold bezel and the iconic Rolex President bracelet in matching solid gold. Powered by the Caliber 2236 with a 55-hour power reserve, the Syloxi silicon hairspring, and Paraflex shock absorbers, the 279178 sits at the top of the Lady-Datejust 28 hierarchy in both material and price. Pre-owned and unworn examples are listed by WatchGuys with full authentication by our in-house watchmakers and our 2-year warranty.

The 279178 is the modern successor to the 26mm Rolex 179178, introduced in 2015 when Rolex updated the Lady-Datejust line from 26mm to 28mm and upgraded the movement from the Caliber 2235 to the Caliber 2236 with the new Syloxi silicon hairspring. The combination of solid yellow gold construction, the President bracelet, and the fluted bezel makes this reference essentially a women's counterpart to the Day-Date 36 in spirit and price tier.

Rolex 279178 Solid 18k Yellow Gold and President Bracelet

The case, fluted bezel, Twinlock screw-down crown, and entire bracelet of the 279178 are crafted from solid 18k yellow gold. There is no Oystersteel anywhere on the watch. This separates the 279178 from two-tone Yellow Rolesor references like the Rolex Datejust 126203 or the Lady-Datejust 279173, which combine steel and gold rather than using solid gold throughout. The bracelet is the Rolex President, the semi-circular three-piece link design originally created in 1956 for the Day-Date and used today on the most premium configurations in both the Day-Date and the Datejust families. Pairing the President bracelet with a solid-gold Lady-Datejust case is one of Rolex's clearest signals that the 279178 sits at the very top of the Lady-Datejust 28 lineup.

Dial options on the 279178 are deliberately curated to complement solid yellow gold. Popular factory configurations include champagne with applied gold baton indexes, champagne with diamond hour markers, silver with Roman numerals, silver with diamond markers, white mother of pearl set with diamonds, and several star-pattern diamond dials. Each dial variant has its own sub-reference code, such as 279178-0017 (champagne diamond), 279178-0025 (white mother of pearl diamond), and 279178-0029 (white dial).

Rolex Lady-Datejust 279178 Price

Pre-owned and unworn Rolex Lady-Datejust 279178 prices typically range from approximately $28,000 to $46,000+ depending on dial configuration, condition, and completeness of box and papers. Standard champagne index and silver Roman dial examples sit at the lower end. Champagne diamond, silver diamond, mother of pearl diamond, and star-pattern diamond dial configurations trade in the upper portion of the range. The intrinsic value of the solid yellow gold case and bracelet provides a meaningful price floor that two-tone Lady-Datejust references do not have. For additional pieces in this tier, see the Rolex watches over $20,000 collection.

Rolex 279178 vs. Rolex 279173

The 279178 and the Rolex Lady-Datejust 279173 are both 28mm Lady-Datejust references with fluted yellow gold bezels and the Caliber 2236 movement, but they sit in completely different price tiers. The 279173 is Yellow Rolesor, combining Oystersteel with 18k yellow gold on the fluted bezel, crown, and center bracelet links (with steel for the case middle and outer bracelet links). The 279178 is solid 18k yellow gold throughout, with the President bracelet rather than the Jubilee or Oyster. The 279173 typically trades between $9,000 and $15,000, while the 279178 trades significantly higher due to gold weight. Buyers choose between them primarily on budget and the desired level of formality. For more on the two-tone option, see the broader two-tone Rolex collection.

  The 279178 replaced the 179178 in 2015. Both are solid 18k yellow gold Lady-Datejust references with fluted bezels and the President bracelet, but the case size and movement changed.
