About the Rolex Datejust 179158

The Rolex Datejust 179158 is the diamond gem-set version of the previous-generation Lady-Datejust 26mm in solid 18k yellow gold, sitting at the top of the diamond-set tier within the discontinued 26mm Lady-Datejust catalog. The 179158 builds on the all-gold construction of the Rolex Datejust 179178 by adding a factory diamond-set bezel and factory diamond-set lugs, giving the watch approximately 66 brilliant-cut diamonds on the case alone before any diamond dial markers are factored in. At WatchGuys, we carry pre-owned and unworn Rolex Datejust 179158 examples across the full range of factory dial configurations, paired with the President bracelet in matching solid 18k yellow gold. The 179158 sits below the Pearlmaster 34 Rolex Datejust 81315 in the diamond-set ladies Rolex Datejust hierarchy, offering a more accessible entry into the heavily gem-set Lady-Datejust tier.

Rolex Datejust 179158 Specifications

The 179158 measures 26mm in diameter and is built entirely from solid 18k yellow gold, with no steel content in the case or bracelet. The case middle, caseback, crown, and the full President bracelet are forged from Rolex's 18k yellow gold alloy. The factory diamond-set bezel features approximately 42 brilliant-cut diamonds in individual yellow gold settings, and the lugs are set with approximately 24 additional diamonds for a combined factory diamond count of approximately 66 stones on the case (before any diamond dial markers). All diamonds are factory-set during production by Rolex, with the case hallmarks and reference number matching the gem-set configuration. Inside is the Caliber 2235, a Superlative Chronometer movement with a 48-hour power reserve, the workhorse Lady-Datejust 26mm movement until Rolex transitioned to the Caliber 2236 with the Syloxi silicon hairspring on the modern 28mm Lady-Datejust in 2015. The Oyster case is water-resistant to 100 meters and features the Twinlock screw-down crown and sapphire crystal with Cyclops magnification over the date.

Rolex Datejust 179158 Dial Options

The 179158 offers a deep range of factory dial configurations, with the diamond bezel and diamond lugs framing each dial in jewelry-leaning brilliance. The champagne dial with factory diamond hour markers in 18k yellow gold settings is the signature configuration, pairing seamlessly against the warm yellow gold case for a fully tonal jewelry expression. The Sundust dial with diamond hour markers offers a similar warm tonal pairing in a more contemporary peachy-pink tone. The slate dial with diamond hour markers provides high contrast against the yellow gold case and bracelet. The white Roman dial with applied gold Roman numerals is the most classic configuration, sometimes referenced under the WHRP designation. Additional options include silver diamond, black with diamond hour markers, and rarer mother of pearl variants. The standard bracelet is the President bracelet in matching solid 18k yellow gold, with semi-circular three-piece links and a concealed folding Crownclasp that hides the closure mechanism entirely within the bracelet flow.

Rolex Datejust 179158 Price

Pre-owned Rolex Datejust 179158 prices typically range from $20,000 to $32,000 depending on dial, condition, and completeness with box and papers. Entry into the reference starts with champagne and slate diamond dial examples in very good pre-owned condition at the lower end of the range. Sundust diamond and white Roman dial variants in excellent condition with full sets sit in the middle to upper end. Rare configurations with original Rolex papers, full unworn condition, or premium dials such as mother of pearl with factory diamond markers can reach $35,000 and beyond. The 179158 trades at a meaningful premium over the non-diamond 179178 sibling, reflecting the additional factory diamonds on the bezel and lugs. It trades below the Pearlmaster 34 81315 on the secondary market, reflecting the standard President bracelet (versus the Pearlmaster bracelet) and the smaller 26mm case. Rolex raised retail prices approximately 7% across the catalog in January 2026. For broader context, browse our full women's Rolex collection.

Rolex Datejust 179158 vs. Rolex Datejust 179178

The 179158 and the 179178 are the two solid 18k yellow gold previous-generation Lady-Datejust 26mm references, and the difference between them comes down to factory gem-setting. The 179158 features a factory diamond-set bezel (approximately 42 brilliant-cut diamonds) AND factory diamond-set lugs (approximately 24 brilliant-cut diamonds), for a combined diamond count of approximately 66 stones on the case alone. The Rolex Datejust 179178 uses a plain fluted yellow gold bezel with no diamonds and plain unadorned lugs. Both share the same 26mm Oyster case, the same Caliber 2235 movement, the same solid 18k yellow gold construction, and the same President bracelet. Many of the same dial colors are shared between the two references. The 179158 trades at a meaningful premium over the 179178 on the secondary market, reflecting the factory diamond content. Buyers who want a fully tonal solid 18k yellow gold ladies Rolex without additional jewelry weight choose the 179178.

Common Questions

Rolex Datejust 179158 FAQ

• How many diamonds are on the Rolex 179158?

  The Rolex 179158 features approximately 42 brilliant-cut diamonds set into the bezel and approximately 24 brilliant-cut diamonds set into the lugs, for a combined factory diamond count of approximately 66 stones on the case alone, before any diamond dial markers are factored in. All diamonds are factory-set during production by Rolex into individual 18k yellow gold settings, not aftermarket additions. Variants with diamond dial markers add another 10 to 11 brilliant-cut stones to the total count. The diamond lugs are the key differentiator separating the 179158 from the 179138 (which has the same diamond bezel but plain unadorned lugs).

• Is the Rolex Datejust 179158 solid gold?

  Yes, the Rolex Datejust 179158 is built entirely from solid 18k yellow gold, with no steel content in the case, bezel, lugs, or bracelet. The case middle, caseback, crown, diamond-set bezel, diamond-set lugs, and the full President bracelet are all forged from Rolex's 18k yellow gold alloy. The solid gold construction is verifiable through the 18k gold hallmarks on the case and bracelet, which we authenticate during inspection along with the reference number, serial number, and factory diamond placements.

• What size is the Rolex Datejust 179158?

  The Rolex Datejust 179158 has a 26mm Oyster case, the original Lady-Datejust dimension introduced by Rolex in 1957 and produced until the brand transitioned to the 28mm Lady-Datejust in 2015. Case thickness is approximately 9mm and lug-to-lug is approximately 31mm. The 26mm size is the most compact modern Lady-Datejust dimension and works particularly well on wrists from approximately 4.75 inches to 6 inches. Buyers seeking a larger contemporary alternative should consider the 28mm 279383RBR (modern Lady-Datejust diamond bezel) or the 34mm Pearlmaster 81315 in Everose gold.

• Rolex 179158 vs. Rolex 179178, what is the difference?

  The 179158 and the 179178 share the same solid 18k yellow gold construction, same 26mm Oyster case, same Caliber 2235 movement, and same President bracelet, but the gem-setting is meaningfully different.

The 179178 uses a plain fluted yellow gold bezel with no diamonds and unadorned lugs. The 179158 trades at a meaningful premium over the 179178 on the secondary market, reflecting the factory diamond content. Buyers who want the all-gold ladies Rolex without additional jewelry weight choose the 179178. Buyers who want a heavily gem-set expression choose the 179158.

• What dials are available on the Rolex Datejust 179158?

The champagne dial with factory diamond hour markers is the signature configuration. The Sundust dial offers a peachy-pink contemporary tone with diamond markers. The slate dial provides high contrast against the yellow gold case. The white Roman dial (sometimes referenced under the WHRP designation) is the most classic configuration with applied gold Roman numerals. Additional options include silver diamond, black with diamond hour markers, and rarer mother of pearl variants. Every dial pairs with the President bracelet in matching solid 18k yellow gold.
