About the Datejust 31
The Datejust 31 occupies a specific and useful position in the Rolex lineup: larger than the Lady-Datejust 28, smaller than the 36, and well-suited to buyers who want a women's Rolex with modern wrist presence without crossing into unisex territory. At 31 mm it is substantial enough to read clearly, refined enough to sit comfortably alongside fine jewelry, and available in enough configurations to suit nearly any personal style.
The Datejust collection dates to 1945, and the 31 mm size carries the same design heritage — Oyster case, Cyclops lens over the date, Twinlock screw-down crown, and the dial variety that makes the Datejust the most configurable watch Rolex produces. Current models run on the calibre 2236 with approximately 55 hours of power reserve and Superlative Chronometer certification.

Current References
278240 — Oystersteel, Smooth Bezel
The cleanest entry into the current Datejust 31 lineup. Full Oystersteel construction with a smooth bezel and either Oyster or Jubilee bracelet. Available in bright blue, black, silver, green, and other dial options depending on availability. The most understated and versatile configuration in the collection — the right choice for buyers who want daily wearability without precious metal complexity.
278274 — White Rolesor, Fluted Bezel
Oystersteel case with an 18K white gold fluted bezel. The bright, silver-tone Rolesor look that many buyers picture when they imagine a classic women's Rolex. Popular across a wide range of dials: black, silver, blue, mint green, white, mother-of-pearl, Roman numeral, and diamond-marker configurations are all strong in this reference.
278273 — Yellow Rolesor
Oystersteel case with 18K yellow gold across the bezel, crown, and bracelet center links. The traditional two-tone Datejust look, most closely associated with champagne, white, and diamond dials on a Jubilee bracelet — a combination that has been recognizably Rolex for decades. Also available with mother-of-pearl, Roman numeral, and black dial configurations.
278271 — Everose Rolesor
Oystersteel with 18K Everose gold — Rolex's proprietary rose gold alloy that maintains its color over time. The warmest and most contemporary of the Rolesor options. Works especially well with chocolate, sundust, white, and mother-of-pearl dials.
278383RBR — Yellow Rolesor, Diamond Bezel
Yellow Rolesor construction with a factory-set diamond bezel. Combines the classic two-tone Rolex look with added brilliance at the bezel. One of the most popular Datejust 31 configurations for buyers who want the watch to function as fine jewelry.
278381RBR — Everose Rolesor, Diamond Bezel
Everose Rolesor with factory diamonds at the bezel. The warm rose tone pairs naturally with the diamonds and works particularly well with sundust and chocolate dial combinations.
278384RBR — White Rolesor, Diamond Bezel
White Rolesor with a factory diamond bezel. The brightest and most overtly dressy of the three diamond bezel Rolesor configurations — popular with silver, white, and mother-of-pearl dials.
Full Gold References
Select Datejust 31 models are produced in 18K yellow gold, white gold, and Everose gold with President bracelets, gem-set bezels, and luxury dial configurations. These references sit at the intersection of watchmaking and fine jewelry and are typically sourced to order.
Discontinued References
178240 — Oystersteel, Smooth Bezel
The previous-generation steel Datejust 31. Clean, practical, and widely available on the pre-owned market. A strong choice for buyers who want an understated Rolex at a lower price point than current production.
178274 — White Rolesor, Fluted Bezel
The discontinued counterpart to the current 278274. Same general construction — Oystersteel with white gold fluted bezel — with the previous-generation case and bracelet details. Popular for its classic Rolex appearance and broad dial availability.
178273 — Yellow Rolesor
Discontinued yellow Rolesor Datejust 31. Often found with champagne, silver, white, mother-of-pearl, Roman numeral, and diamond-marker dials. A reliable pre-owned choice for the traditional two-tone Datejust look at a more accessible price.
178271 — Everose Rolesor
Discontinued Everose Rolesor Datejust 31. Warm two-tone character with strong availability in chocolate, sundust, and mother-of-pearl dials. Popular with buyers who want the rose-tone Datejust at a discontinued reference price point.
Earlier Mid-Size References
Older mid-size Datejust references in the 68- and 78-series (68273, 68274, 78273, 78274) appear periodically on the pre-owned market for buyers who want a more vintage character or a smaller budget entry into the Datejust family.
Movement
Current Datejust 31 references use the Rolex calibre 2236, an in-house automatic movement developed specifically for Rolex's mid-size cases. It features a Syloxi silicon hairspring for paramagnetic performance and resistance to magnetic interference, an instantaneous date display with rapid-setting function, stop-seconds for precise time setting, and approximately 55 hours of power reserve. The calibre 2236 meets Rolex's Superlative Chronometer standard of ±2 seconds per day after casing.
Discontinued 178-series references use the calibre 2235, the previous-generation equivalent. Older mid-size references may use earlier Rolex calibres depending on production era.
Dials
The Datejust 31 offers more dial variety than almost any other watch Rolex produces. Some configurations worth knowing:
Champagne — The classic choice on yellow Rolesor models, where the warm dial tone complements the gold accents naturally. One of the most timelessly Rolex combinations available.
Mint green and bright blue — Popular modern options that give the watch a fresher, more contemporary character. Both read well on Oystersteel and Rolesor references.
Mother-of-pearl — Shifts the watch into fine jewelry territory. Works across all Rolesor metals and is frequently chosen for gift or milestone purchases.
Roman numeral — Adds a dressier, more traditional Rolex character. Often paired with fluted bezel and Jubilee bracelet configurations.
Diamond-marker — Factory-set diamond hour markers in place of baton indices. Available across Rolesor references and adds a significant jewelry presence without the full weight of a diamond bezel.
Chocolate and sundust — Distinctive and specific to Everose Rolesor references. Less common than blue or silver and often sought by buyers who want something less standard.
Floral and motif dials — Select references feature decorative factory dials with floral, palm, or fluted motifs. These are the most jewelry-forward configurations in the standard Datejust 31 catalog.
Bracelets and Bezels
Jubilee — Five-piece link construction, created for the original Datejust in 1945. Dressier, more flexible, and more traditionally associated with the model. Pairs especially well with fluted bezel and Rolesor configurations.
Oyster — Three-piece link construction with a cleaner, more sport-adjacent look. The right choice for buyers who want the Datejust 31 to feel modern and everyday rather than formal.
President — Available on full precious metal references. The most overtly luxurious bracelet option, with a more jewelry-like presence than either the Jubilee or Oyster.
Smooth bezel — Clean and understated. Most common on Oystersteel references, where the absence of decorative detail keeps the watch simple and versatile.
Fluted bezel — On Datejust 31 models, the fluted bezel is solid 18K gold (yellow, white, or Everose depending on the reference). Catches light and signals precious metal without requiring a full gold case.
Diamond bezel — Factory-set diamonds across the full bezel circumference. The highest jewelry intensity available in the standard Datejust 31 catalog. Meaningfully affects both the look and the price.
How the 31 Compares
Datejust 31 vs. Lady-Datejust 28 — The 28 is smaller and more traditionally feminine, sitting closer to the fine jewelry end of the spectrum. The 31 offers more dial presence and is easier to read on the wrist. Buyers who want a Rolex that functions as a watch as much as an accessory generally prefer the 31; buyers who prioritize delicacy and lightness often prefer the 28.
Datejust 31 vs. Datejust 36 — The 36 is the classic unisex Datejust size — more assertive, better suited to larger wrists, and available in a wider range of references including full Oystersteel models on Oyster bracelets that are frequently worn by men. The 31 is more specifically feminine in character and proportion. Buyers who sit between the two sizes should try both on if possible; the difference in wrist feel is more significant than the 5 mm suggests.
