Serial numbers
- ? – ? (2017–?) — Since around 2010, Rolex has used random alphanumeric 8-digit serial numbers without a year code. Dating by serial number is not possible for Ref. 279178. The serial number is engraved on the rehaut (inner bezel ring).
Search for reference 279178 in the trade and you'll run into at least three names for it: LDJ 28 YG Fluted, Lady-Datejust 28 Yellow Gold, Lady DJ 279178. They all refer to the same 28-millimeter case with a fluted bezel in 18-karat yellow gold. Inside sits caliber 2236, Rolex's own movement with a silicon hairspring, also found in the larger Datejust models and standard on the 279178 since its launch.
## Five New Dial Colors Since 2022
The real story on this reference is the dial lineup. Starting around 2022/2023, Rolex expanded the range with five new versions: cornflower blue with diamond hour markers under code 0009, mint green with diamond-set surround, green under 0028, white under 0029, and a full diamond-paved dial under 0031. That brings the catalogued dial count to nine for this reference, ranging from simple markers to full pavé — all listed as running in parallel, per Coveted's overview (as of 2024).
## The Classics Stay Standard, Color Becomes a Choice
Champagne, silver, and mother-of-pearl haven't been pushed out by the expansion — they're still very much in production. Looking for a 279178 in one of the classic finishes? You'll find the Champagne Index Dial, the Silver Sunburst Index Dial, or the Diamond-Star variants in champagne, silver, and mother-of-pearl. The fluted yellow gold bezel stays identical across all nine dial codes — only the face changes. So when it comes to valuing a specific 279178, the dial code is what matters first, with case and caliber a distant second.
Brand profile: Rolex
Rolex is the most counterfeited watch brand in the world. Super-clones (VSF, ARF, Clean — the latter inactive since the 07/2025 raid, with only old stock still circulating) reach 95%+ similarity. Authenticity can almost always only be identified through micro-details and caliber behavior.
- Case back: ALWAYS solid and closed — any display window means it's definitely fake (exception: vintage Ref. 6085 only)
- Minute hand length: genuine Rolex minute hands end EXACTLY at the minute chapter ring. 1 mm too long = fake. The strongest VSF tell.
- Seconds hand: smooth sweep without any hesitation — the slightest tick-tock motion means it's fake
- Cyclops lens (on Date models): must magnify exactly 2.5×, with the date filling almost the entire window
Serial number format: Since 2010, a random alphanumeric combination (e.g. 'G3M9K721'). 2000-2010: a letter plus 6-7 digits. Serial number engraved on the rehaut at 6 o'clock (from ~2005). Older models: between the lug shoulders at 6 o'clock on the case.

What drives the price here
At $37,896 the watch sells well if the condition is right. A market rule of thumb: a complete set with box, papers and warranty card brings 10 to 15 percent more than the bare watch. Buying without papers can pay off, but you take the same discount again later when you resell.
Watch out for swings: This reference has an above-average volatility of 116.7 percent. In concrete terms: the price can move by several hundred euros within a few weeks. Check the current value before buying or selling — old listings or auction results from two months ago are of little help.

- Authenticity: The serial number and reference on the case must match the papers. A professional authenticity check of the Rolex Lady-Datejust 28 18 kt Gelbgold Champagner reliably rules out counterfeits.
- Condition: Check scratches on the case and bezel — professional refurbishment can leave traces.
- Service history: A documented service by the manufacturer or a certified watchmaker increases the value.
- Scope of delivery: Box, papers and warranty card make a noticeable price difference on the Lady-Datejust 28 18 kt Gelbgold Champagner.
- Independent certification: The CPS-52 standard covers 52 checkpoints — from the serial number and the timing machine to water resistance. The result is secured on the blockchain and can be verified at any time.
