Iconic Style in Smaller Sizes
The Rolex ladies Datejust watches are some of the most iconic luxury watches ever made. It’s a symbol of elegance, precision and timeless style. For women and those with an attraction to smaller watches, Rolex offers the Datejust in more compact case sizes. Notably 28mm, the classic “Lady Datejust” and 31mm, often dubbed mid size or unisex. These smaller Datejust models combine all the hallmark Rolex quality and design in a more refined scale, making these luxury watches ideal for a slender wrist, or a subtle everyday luxury statement. In this guide we will look into the 28mm and 31mm Rolex Datejust models, exploring their history, dial and bezel options, investment value and how they compare to larger unisex sizes. We’ll also highlight real examples from Kettle Club’s catalogue to illustrate these beautiful timepieces in action.
A Brief History of Rolex Ladies Datejust Sizes
Rolex introduced the first ladies’ Datejust, officially the “Lady Datejust” in 1957 as a dainty 26mm watch, following the men’s 36mm Datejust which debuted in 1945. That tiny 26mm size remained the standard for nearly six decades. In 2015, Rolex unveiled the Lady Datejust 28, upsizing the case to 28mm to give the classic women’s watch a slightly larger, more modern profile. Early Lady Datejust 28 models came only in precious metals or two tone Rolesor, steel and gold, but by 2017 Rolex had expanded the line to include stainless steel versions as well. The 31mm Datejust actually dates back much further, Rolex introduced a 31mm mid size Datejust in the late 1950s as a bridge between the petite ladies’ watch and the larger men’s watches. Over the years, the 31mm variant became one of the best selling Datejust sizes among women, valued for offering a bit more wrist presence than the classic Lady model while still looking elegant and proportional. Today, the 28mm and 31mm models are both part of Rolex’s current production, with the 28mm still officially labeled “Lady Datejust” and the 31mm often just called Datejust 31. Each has its own appeal and Rolex gives both sizes outstanding variety in metals, dials and bezels so every wearer can find her perfect combination.
Ladies Datejust 28mm: Timeless Petite Elegance
At 28mm, the Lady Datejust represents the quintessential ladies’ Rolex, a refined, classic dress watch that exudes subtle elegance. It retains all the signature Datejust features: the date window at 3 o’clock with Cyclops magnifier, the Oyster waterproof case, 100m water resistance and an automatic “Perpetual” movement renowned for accuracy. In 2015 when Rolex upsized from 26mm to 28mm, they also introduced the new Caliber 2236 movement with a Syloxi silicon hairspring for improved precision and a 55 hour power reserve. The result is a tiny watch that is as robust and technically advanced as larger models.
Visually, the Lady Datejust 28 maintains a delicate, feminine charm on the wrist. Many consider the 28mm size the most traditional “ladies’ watch” look, it’s petite and pairs beautifully with formal attire or as a discreet daily luxury. On smaller wrists, 28mm sits proportionally and has a jewellery like quality. As one observer noted, a 28mm can look “more feminine and dressy”, whereas a larger 31mm starts to give more standard watch presence. Rolex offers the Lady Datejust 28 in a wide range of materials and styles. You can choose from all stainless steel, two tone Rolesor in yellow or Everose, rose gold or full 18k gold, yellow, white or Everose. Bezels come in three styles, smooth, domed, fluted gold or gem set with diamonds, and dials span virtually every colour and texture imaginable. Early 28mm models were mostly in gold and notably Rolex pairs its precious metal Lady Datejust watches with the elegant President bracelet, a rounded three link design usually reserved for Day Date models, hence the nickname “Ladies’ President” for these watches. More recent steel versions of the 28mm can be found on sporty Oyster bracelets or dressy Jubilee bracelets, depending on the bezel and dial combination. In short, the Lady Datejust 28 delivers timeless Rolex style in a perfectly petite package, making it a favorite for those who prefer a classic ladies’ size. And despite its smaller size, it loses none of the quality, both the 28mm and 31mm models are built to the same Rolex standards, including robust waterproof cases and chronometer certified movements, meaning they are just as durable for daily wear.
A great illustration of the Lady Datejust’s enduring charm is the Rolex Datejust ref. 69173, 26mm from 1992, a vintage two tone model featuring a blue “vignette” dial with diamond hour markers. This predecessor to the 28mm Lady Datejust shows the classic combination of 18k yellow gold and Oystersteel, Jubilee bracelet and a fluted bezel, a style still very much alive in the modern 28mm references. Kettle Club’s example from 1992 retains its beauty and showcases how these watches hold up over time, both in style and value, this piece, with original box and papers, is offered around the mid £4,000s. Whether vintage or modern, a Lady Datejust in the 26–28mm size is a truly timeless accessory.
Datejust 31mm: Versatile Mid Size Appeal
The 31mm Datejust occupies an interesting middle ground in Rolex’s lineup, it’s larger than the traditional ladies’ watch, yet smaller than a gents’ 36mm. This makes it an extremely versatile choice. In Rolex’s words, the 31mm was designed as “a man’s watch women prefer to wear,” implying it was created for women seeking a bolder look. Indeed, many modern women gravitate to the 31mm Datejust because it offers a noticeable step up in wrist presence over the 28mm model, without venturing into oversized territory. On the wrist, 31mm has more dial real estate, which can make the watch easier to read and more of a statement piece, yet it still maintains elegance and doesn’t overpower a slimmer wrist. It’s no surprise that the Datejust 31 has in recent years become “the most popular piece in the range among women”, thanks to its highly versatile size and style options.
Rolex treats the 31mm Datejust much the same as the Lady Datejust in terms of variety, in fact, Rolex’s current catalog offers even more variations in the 31mm size than in the 28mm. The Datejust 31 is available in seven metal combinations, stainless steel, White, Yellow or Everose Rolesor and solid 18k Yellow, White or Everose gold. Like the 28mm, you have a choice of smooth, fluted or diamond set bezels, paired with Oyster, Jubilee or President bracelets, President reserved for all gold models. Dial options are especially diverse, from classic black, silver or white dials to vibrant hues like mint green, pink or rich aubergine. Rolex also offers luxurious dial materials at 31mm, including mother of pearl, malachite and full pavé diamond dials for those who want extra sparkle. In terms of functionality and build, the Datejust 31 carries the same technical excellence: the latest models use the Caliber 2236 automatic movement, the same as the 28mm with the silicon Syloxi hairspring for superb accuracy and stability and of course the watch is Oyster cased and Twinlock sealed for 100m water resistance, tough enough for daily wear despite its luxury status.
A key appeal of the 31mm is that it can easily be considered unisex. While marketed toward women, its size and design make it wearable by anyone who prefers a mid size watch. In fact, some collectors note there’s “no special lady features” on a Datejust 31, it’s essentially the same Datejust design scaled down, so men who dislike large watches or teenagers, for example, could wear a 31mm just as well. For most buyers, however, the 31mm strikes the perfect balance of elegance and presence for a modern ladies’ watch. It can be dressed up or down effortlessly, put it on a Jubilee bracelet with a fluted bezel and Roman numeral dial for a classic dress look or opt for a smooth bezel on Oyster bracelet with a bright dial for a more contemporary, casual vibe.
Our collection features some stunning Datejust 31 models that showcase the range’s versatility. For instance, the Rolex Datejust ref. 278274, 31mm in Oystersteel and white gold with a mint green dial is a current model piece from 2025, pairing the trendy new green sunray dial with a white gold fluted bezel and Jubilee bracelet. It offers a modern pop of colour while retaining that timeless Datejust style, truly the best of both worlds. We also have a two tone Rolex Datejust ref. 178273, 31mm from 2007, which features yellow Rolesor, steel with 18k yellow gold accents, a black dial and diamond hour markers. This highlights how the mid size Datejust can exude a luxurious feel, with the warmth of gold and sparkle of diamonds, yet in a wearable size. Both of these examples underline why the 31mm is so popular today, whether you favor cutting edge dial colours or classic two tone elegance, the Datejust 31 delivers a highly versatile luxury watch that appeals to a wide audience.
Dial & Bezel Options: Endless Variety and Personalisation
One of the most exciting aspects of the 28mm and 31mm Datejust models is the astonishing variety of configurations Rolex offers. These may be smaller watches, but they are by no means limited in style. Between the two sizes, Rolex’s catalog spans dozens upon dozens of references, the Datejust truly is “about the most chameleonic creation in Rolex’s entire portfolio” in terms of available combinations. Here’s an overview of the options you can consider when choosing a Ladies’ Datejust in 28mm or 31mm size:
- Materials & Bracelets: Both sizes are offered in stainless steel, steel and gold, Rolesor or full 18k gold variants. Rolesor models can be with yellow gold or Rolex’s Everose pink gold and the steel/gold combos add a touch of luxury without the price of full gold. The bracelet can dramatically influence the watch’s character: a sporty three link Oyster bracelet gives a clean and modern look, the five link Jubilee bracelet adds dressy vintage flair, it was originally designed for the Datejust in 1945 and the President bracelet on gold models lends an unmistakably high end, sophisticated feel. Notably, Rolex only fits the President bracelet on solid gold ladies’ models, steel or two tone Datejusts come with Oyster or Jubilee options.
- Bezels: The bezel is a defining trait of the Datejust’s style. Smooth, domed bezels offer a sleek and understated elegance, usually seen on stainless steel references. The iconic fluted bezel, always crafted in gold, even on steel watches it will be white gold, provides that classic Rolex look, it catches the light and instantly signals the watch’s heritage. For those who love sparkle, Rolex also produces factory diamond set bezels on many 28mm and 31mm references, often denoted by reference numbers ending in “3” like 279383 or 278288. A gem set bezel elevates the watch into true jewellery territory and Rolex’s craftsmanship here is on full display with perfectly matched diamonds. For example, one modern 31mm reference features 46 brilliant cut diamonds in its bezel and an aubergine, plum sunray dial with diamond Roman numeral VI, a striking blend of elegance and glamour. Whether you prefer the subtlety of a smooth bezel, the traditional fluted look or the opulence of diamonds, there’s a Datejust to match.
- Dials: Rolex is renowned for offering a rainbow of dial choices and the ladies’ Datejust lineup is perhaps where their dial catalogue is most expansive. You’ll find classic colours like black, white, silver and champagne, feminine hues such as pink, lavender or the popular new mint green and specialty dials including Mother of Pearl, MOP, which shimmers with an iridescent effect and hard stone dials like malachite or turquoise on some high end versions. In vintage pieces, you might encounter unique finishes like the “Blue Vignette” dial, a blue to black gradient fade with diamond markers on our 1990s ref. 69173 example. Hour markers add another layer of customisation, you can have the sharp look of baton, stick indices, elegant Roman numerals, playful Arabic numerals or diamond hour markers set into the dial. Combinations are nearly endless: for instance, our Kettle Club 2025 Datejust 31 ref. 278273 in yellow Rolesor pairs a classic champagne dial with diamond markers for a touch of luxury, while another variant like the ref. 278271 in Everose Rolesor might feature a rich chocolate brown dial with Roman numerals for a warm, refined style. Rolex’s own website dedicated to the Datejust 31 runs 32 pages long because of all these permutations! Clearly, personalisation is the name of the game, whatever your taste, there’s likely a dial/bezel combo to suit it.
This breadth of choice means that two women could both own a “Datejust 31” yet have completely different looking watches, one might be a stainless model with a smooth bezel and bright coral dial, another a two tone with fluted bezel and mother of pearl diamond dial. The luxury and expressiveness of the Datejust in these sizes make it akin to fine jewellery, you can truly select the metals and colours that speak to you. And thanks to Rolex’s modular approach, within certain limits, many of these elements are transposable, e.g. a steel watch can have any colour dial with batons or Romans, a Rolesor can mix various dials with or without diamonds, ensuring that virtually no two Datejusts out there are exactly alike. This is a big part of the Datejust’s enduring appeal as a ladies’ watch: it can be as understated or as dazzling as you wish.
Comparing 28mm vs 31mm vs Unisex Options
When deciding between the 28mm and 31mm Datejust, a lot comes down to personal preference and wrist size. Here’s a quick comparison to help guide you:
- Wrist Presence: The 28mm is subtle and traditionally feminine, it looks delicate and won’t dominate a small wrist. The 31mm, on the other hand, has a bolder presence and is more noticeable as a wristwatch. If you want your Rolex to stand out a bit more or have an easier read, the 31mm might be preferable, whereas if you favor a more discreet elegance or have a very slim wrist, the 28mm is ideal.
- Trend & Style: In today’s fashion, there’s a clear trend of women wearing larger watches. Many women even wear the 36mm Datejust or 40mm sport models to embrace a chunky, statement look. Within this context, the 31mm can be seen as a modern choice that aligns with the move toward slightly larger watches for women. It has been described as a midsize that “appeals to a wide audience, particularly women who seek both elegance and presence”. The 28mm remains a classic choice, it never looks out of place at a formal event or with jewellery. Think of the 28mm as a timeless pearl necklace and the 31mm as a contemporary pendant, both beautiful, but with different vibes.
- Unisex Wear: As mentioned, the 31mm can cross over to men or be considered unisex, especially for those who prefer smaller watches. The 36mm Datejust, the original men’s size is now often worn by women as well, in fact, Kettle Club lists some 36mm models in our Ladies’ collection, such as a Rolex Datejust 36 ref. 16234, 36mm from 2001 with a classic stainless steel and white gold fluted configuration. Many women enjoy the 36mm for its “bold aesthetic” and it can certainly make a confident fashion statement if you’re comfortable with a larger watch on your wrist. Conversely, some men with smaller wrists wear 31mm Datejusts or vintage 30-34mm models, it truly comes down to comfort and style preference. Rolex also historically made a 34mm Date model and currently makes 34mm Oyster Perpetuals, these could be considered “mid size” as well, though they are less common. In summary, 28mm = definitively feminine and petite, 31mm = sweet spot versatile, leaning feminine but unisex friendly and 36mm+ = traditionally men’s but increasingly unisex for those who like larger looks. There is no wrong choice, it’s all about what feels and looks right on your wrist.
Investment Value and Collectibility
When purchasing a luxury watch like a Rolex, it’s natural to consider how well it holds its value. The good news is that Rolex Datejusts, regardless of size, tend to retain value better than almost any other watch in their class. That said, the market dynamics for the smaller ladies’ models can differ a bit from the ultra sought after men’s sports models. Here are some key points on investment and value:
- Historic Affordability: Because Rolex produced the Lady Datejust and mid size Datejust in large numbers and they were long readily available, the pre owned market is well supplied with these watches. Unlike steel sport Rolex models, which can far exceed retail price pre owned due to scarcity, many pre owned ladies’ Datejusts can be found at very attractive prices. As one industry review noted, Rolex never heavily restricted supply of Datejusts, so “there are plenty in circulation, keeping prices extremely reasonable”. For example, a previous generation Datejust 31, reference 178XXX, pre 2019 in stainless steel can be had around ~£3,800 and even two tone or gold models often under £7,600, a great value for the quality and prestige. Vintage 26mm models from the 1980s–90s can sometimes be found in the low thousands of pounds, which is quite accessible as an entry point to the Rolex world.
- Modern Demand: In recent years, certain dial variants of the Datejust 31 have spiked in popularity, notably the mint green dial and the Wimbledon, dark rhodium with green Roman numerals on 36/41mm. A new Rolex Datejust 31 in steel with a green dial retails around £6k, but some dealers have sold pre owned pieces for as high as £6.8k due to demand. This shows that if a particular configuration is hot or short in supply, even the smaller models can appreciate or at least fetch strong resale prices. Generally, popular dial/colours, green, pink, MOP, diamond dials and anything with factory diamonds or in gold will hold value very well because of their desirability and intrinsic material value. It’s worth noting that Rolex’s annual price increases also lift the floor for pre owned prices, so a watch bought a few years ago could potentially be sold for near what you paid if kept in great condition.
- Condition and Completeness: As with all luxury watches, the condition of the watch and presence of original box and papers can significantly impact value. Collectors will pay a premium for well preserved pieces with documentation. For ladies’ watches specifically, some vintage pieces with original diamond dials/bezels and papers are quite sought after. Kettle Club always emphasizes keeping your watch in excellent condition; for instance, diamond set ladies’ watches from top brands often hold their value well, especially if kept with original papers.
- Long Term Outlook: While smaller gold and diamond watches were sometimes undervalued in the past, as the market chased steel sports models, there is a sense that quality and rarity will shine through in the long run. A classic Rolex Datejust, whether 28mm or 31mm, will likely always have a market of buyers due to the model’s heritage. They are also often treasured as heirlooms, passed from one generation to the next, which speaks to their lasting value beyond just price. You likely won’t see the ladies’ Datejust double in price overnight, but you can be confident that it won’t “tank” either. In fact, when you factor in years of enjoyment, a well bought pre owned Datejust can be considered a savvy investment in both style and value retention. And if you ever do decide to sell or trade, the Rolex name ensures strong liquidity, as one expert quips, you can bet you’ll get a better return with a Rolex than with virtually any other watch brand.
