What You’re Looking At
The Rolex Lady Datejust 28 Rose Gold Steel Aubergine Diamond Dial 279171 is the smallest Datejust Rolex currently makes, designed specifically for women with wrists under 6 inches. What makes this particular reference stand out is the aubergine dial, a deep, dark purple with a sunray finish that shifts in different lighting, paired with 10 factory-set diamonds housed in rose gold. It sits in the mid-range of Rolex Datejust Lady Datejust 28 Steel Rose Gold pricing, combining the iconic fluted rose gold bezel with the sportier Oyster bracelet.

What the Specs Mean in Practice
The 28mm case is small, but that’s the whole point. Rolex used to make a 26mm version that proved too difficult to read, so they bumped it up to 28mm for better legibility while keeping the proportions right for smaller wrists. At 11mm thick, the Lady Datejust 28 Aubergine Diamond Dial stays slim enough to slide under a cuff without feeling like a compromise. The steel case houses the dial, hands, and movement, keeping the watch robust where it counts. Rose gold shows up on the bezel and the diamond settings on the dial, giving you precious metal accents without the weight or price of a full gold case.
The Caliber 2236 replaced the older 2235 and delivers 55 hours of power reserve. That means you can take it off Friday night and put it back on Monday morning without resetting. The 100-meter water resistance is more than adequate for a dress watch.
Design Details
The aubergine dial is the star here. It’s not a loud purple. It’s a dark, refined shade that still manages to give the watch real personality. The sunray finish means the dial catches light differently as you move, so it never looks static. Rolex sources perfect diamonds for the 10 hour markers, and they’re placed with the precision you’d expect. The rose gold setting for each diamond ties into the rose gold fluted bezel, creating a cohesive look.
The fluted bezel itself is probably the most recognizable Rolex design element after the crown logo. It used to serve a functional purpose for waterproofing, but now it’s purely aesthetic. And honestly, this is the configuration to get. Diamond bezels exist, but the standard fluted bezel in rose gold is the classic choice.

On the Wrist
The Rolex Lady Datejust 28 Rose Gold Steel 279171 wears small but fits a lot of women better than larger options. The Oyster bracelet gives it a sportier, more contemporary feel compared to the Jubilee option. And because the Oyster links are larger, the watch actually appears a bit bigger on the wrist than the 28mm case size might suggest. One practical advantage of this configuration: the Oyster bracelet includes a comfort extension that can add about 5mm of length. The Jubilee version doesn’t have this feature.
Who Should Buy This
This watch makes the most sense for medium-sized women or smaller. If your wrist is under 6 inches, the 28mm case will look proportionally correct rather than undersized. The reviewer pointed out that the Lady Datejust 28 probably deserves to be a better seller than it is. A lot of women jump to the 31mm or 36mm when the 28mm would actually suit them better. It’s worth considering if proper fit matters to you more than following the current trend toward larger watches.
The aubergine dial adds personality without being flashy. The dark purple reads as sophisticated and pairs well with most outfits. If you want something more distinctive than a standard silver or champagne dial but still want to keep things classy, this is a solid choice. It also works well as a watch for older women or anyone who prefers a more delicate presence on the wrist.

The Rolex Lady Datejust 28 Aubergine Diamond Dial 279171 gets two thumbs up. The combination of rose gold and steel with that deep purple sunray dial hits a sweet spot between everyday wearability and refined elegance.
