About 28mm Rolex Watches

The 28mm Rolex is the current-generation Lady-Datejust, introduced in 2015 as the successor to the long-running 26mm Lady-Datejust. It is the smallest case size in the modern Rolex Datejust lineup and the cornerstone of the women's Rolex collection. At WatchGuys, we stock pre-owned and unworn 28mm Rolex watches across every material tier and bezel configuration, each authenticated in-house and backed by our 2-year warranty.

Which Rolex Models Come in 28mm?

The 28mm case size is exclusive to the Rolex Lady-Datejust (reference 279XXX series). The range includes the ref. 279160 in full Oystersteel with a domed bezel, the ref. 279174 pairing Oystersteel with a white gold fluted bezel, and the ref. 279173 combining Oystersteel with yellow gold. Full 18k gold models include the ref. 279178 (yellow gold) and ref. 279175 (Everose gold). Diamond-bezel variants sit at the top of the range. All 28mm Lady-Datejust models are powered by the Caliber 2236 with Rolex's Syloxi silicon hairspring, delivering 55 hours of power reserve. For the full reference breakdown, see our Rolex Datejust Buyer's Guide.

28mm Rolex Price

Pre-owned 28mm Rolex prices depend on material, bezel type, dial configuration, and condition. As of 2026, Oystersteel Lady-Datejust models (ref. 279160) typically start around $6,000 to $9,000. Two-tone Rolesor models (refs. 279173, 279174) generally range from $7,000 to $12,000. Solid 18k gold models start around $12,000 and can exceed $25,000 for diamond-set configurations.

28mm vs 26mm Rolex

The 28mm Lady-Datejust replaced the 26mm Lady-Datejust in 2015. The 2mm increase brings a slightly bolder wrist presence while preserving the collection's refined proportions. The 28mm models run on the newer Caliber 2236 with a Syloxi hairspring and 55-hour power reserve, a meaningful upgrade from the Caliber 2235 in the outgoing 26mm references. For shoppers who prefer the classic 26mm proportions, pre-owned 26mm references remain available at a lower price point.

Common Questions

28mm Rolex FAQ

• What Rolex models come in 28mm?

  The 28mm case size is exclusive to the Rolex Lady-Datejust (reference 279XXX series). No other current or recent Rolex model uses a 28mm case. The Lady-Datejust 28 is available in Oystersteel, two-tone Rolesor (steel with yellow, Everose, or white gold), and solid 18k gold, with smooth, fluted, or diamond-set bezels and Oyster, Jubilee, or President bracelets.

• How much does a 28mm Rolex cost?

  Pre-owned 28mm Rolex prices in 2026 start around $6,000 for an Oystersteel Lady-Datejust (ref. 279160) in good condition and range to $25,000 or more for solid 18k gold models with factory diamond bezels. Two-tone Rolesor models typically fall between $7,000 and $12,000 depending on condition and configuration.

• Is a 28mm Rolex too small?

  The 28mm Rolex Lady-Datejust is designed for smaller wrists and wears comfortably on wrists measuring approximately 5.5 to 6.5 inches. It is the most refined and traditionally proportioned women's Rolex size. If you prefer a larger watch, the Datejust 31 offers more wrist presence while keeping a feminine profile, and many women also wear the unisex Datejust 36.

• 28mm vs 26mm Rolex, what is the difference?

  The 28mm Lady-Datejust (ref. 279XXX, 2015 to present) replaced the 26mm Lady-Datejust (ref. 179XXX and earlier). The 28mm has a slightly larger case, updated proportions, and the Caliber 2236 movement with a Syloxi hairspring and 55-hour power reserve. The 26mm uses the older Caliber 2235 with a shorter power reserve. The 26mm is discontinued but remains available pre-owned at a lower price point.

• What movement is in the 28mm Rolex Lady-Datejust?

  All current 28mm Rolex Lady-Datejust watches use the Caliber 2236, an automatic movement with Rolex's Syloxi silicon hairspring. The Syloxi hairspring is virtually unaffected by magnetic fields, highly resistant to temperature variations, and contributes to the movement's Superlative Chronometer certification. The Caliber 2236 provides a 55-hour power reserve.
