About the Rolex Datejust 178384

The Rolex Datejust 178384 is the discontinued 31mm Datejust 31 in Oystersteel with a factory 18k white gold diamond bezel set with 46 brilliant-cut diamonds, making it the most accessible factory diamond bezel Rolex Datejust on the secondary market. It features a 31mm Oyster case in 904L Oystersteel, an 18k white gold bezel set with 46 brilliant-cut diamonds at the factory, an Oystersteel screw-down Twinlock crown, sapphire crystal with Cyclops lens, and is powered by the COSC-certified Caliber 2235 self-winding movement with a 48-hour power reserve. The 178384 is fitted with either the three-link Oyster bracelet or the five-link Jubilee bracelet in matching Oystersteel, with the Oysterclasp and Easylink 5mm comfort extension. Importantly, the 178384's diamond bezel is a factory-set Rolex configuration, not aftermarket: the bezel itself is constructed in 18k white gold (rather than steel) specifically to hold the 46 hand-set brilliant-cut diamonds. Rolex does not produce diamond bezels in steel because the gemstone setting requires the malleability of solid gold. The 178384 was produced from approximately 2007 through 2018 before being replaced in the current Rolex catalog by the modern 278384RBR, which uses the updated Caliber 2236 with a Syloxi silicon hairspring. According to WatchCharts secondary market data as of April 2026, the 178384 has a market value of approximately $13,011, which represents roughly a $7,000 premium over the all-steel smooth-bezel sibling 178240 and a meaningful discount versus the modern 278384RBR successor at $18,061-$19,003. The 178384 also offers the broadest dial menu in the entire Datejust 31 catalog, ranging from mother of pearl Roman to floral motif to Goldust Dream and beyond. At WatchGuys, every Rolex Datejust 178384 listed in our Rolex watches collection is authenticated by our in-house watchmakers and ships with a 2-year warranty.

What Makes the Rolex Datejust 178384 Unique

The 178384 is the most accessible entry into the factory diamond bezel Rolex ecosystem and offers the broadest dial menu of any Datejust 31 reference. The 31mm midsize case makes the 178384 genuinely unisex in proportion, splitting the difference between the 36mm classic Datejust and the 28mm Lady-Datejust, and the diamond bezel adds presence on the wrist that feels significantly larger than 31mm. The factory 18k white gold diamond bezel features 46 hand-set brilliant-cut diamonds in a single row around the bezel, set into solid 18k white gold that bridges the steel case to the bezel itself. This is the same diamond bezel construction found on the larger and more expensive 126284RBR Datejust 36 and 178344 Lady-Datejust references. The dial menu on the 178384 is the broadest in the Datejust 31 catalog: mother of pearl Roman (white and black variants), mother of pearl diamond, silver Jubilee diamond, blue concentric Arabic, silver floral motif, slate floral motif, rhodium grey floral motif, black Roman, purple Roman, and the rare Goldust Dream Roman with its champagne metallic finish. The diamond hour marker variants pair multiple diamond placements (typically a featured diamond-set VI marker or full diamond pave hour markers) with the diamond bezel for the most jewelry-forward configurations. Inside the case sits the Caliber 2235, Rolex's smaller-format chronometer-certified automatic movement designed specifically for the 31mm and 26mm cases.

According to WatchCharts secondary market data as of April 2026, the 178384 has a market value of approximately $13,011.

Rolex 178384 vs. 178240 vs. 278384RBR vs. 126284RBR

The 178384 sits at the intersection of one direct sibling reference, one important successor, and one important size-up sibling. The Rolex Datejust 178240 is the same 31mm Datejust 31 in identical case construction with the same Caliber 2235 movement, but with a smooth Oystersteel bezel instead of the diamond bezel. The 178384 typically trades roughly $7,000 above the 178240 on the secondary market, which is the quantifiable value of the factory 18k white gold diamond bezel set with 46 brilliant-cut diamonds. Stepping forward in time, the modern current-production 278384RBR is the direct successor in the same diamond bezel format, using the updated Caliber 2236 with the Syloxi silicon hairspring and a 55-hour power reserve. The 278384RBR typically trades $5,000 to $6,000 above the 178384 due to the newer movement, current-production status, and modern bezel refinements. Stepping up in size, the 126284RBR is the current-production Datejust 36 with a similar diamond bezel construction, trading at approximately $19,880 on the secondary market. The size-up to 36mm adds noticeable wrist presence and uses the modern Caliber 3235 (70-hour power reserve), but at significantly higher pricing than the 31mm 178384. For a smaller alternative in the same family, the 179174 Lady-Datejust 26 with diamond bezel offers the most compact option. For the Everose Rolesor diamond-bezel sibling, the Rolex Datejust 178241 family includes the 178341 with diamond hour markers, while the modern 278341RBR adds the diamond bezel to the Everose Rolesor configuration. For a broader white gold fluted bezel alternative without diamonds, the modern Rolex Datejust 278274 in 31mm offers a more restrained current-production option in the same case size. The choice between the 178384 and these comparison references comes down to whether the diamond bezel premium is worth the price, and whether discontinued or current-production status matters for the buyer.

Common Questions

Rolex Datejust 178384 FAQ

• Is the Rolex Datejust 178384 still in production?

  No, the Rolex Datejust 178384 has been discontinued. It was produced from approximately 2007 through 2018 and was replaced in the current Rolex catalog by the modern 278384RBR, which features the updated Caliber 2236 with a Syloxi silicon hairspring and modern bezel refinements. The 178384 is now only available on the secondary market through trusted pre-owned dealers like WatchGuys. As a discontinued reference, the 178384 has the advantage of no authorized dealer waitlist, no allocation uncertainty, and a meaningful discount versus the current-production 278384RBR successor. Buyers who want the modern Caliber 2236 movement step up to the 278384RBR, while buyers who want the diamond bezel at the most accessible pricing choose the discontinued 178384. The 178384 is the predecessor to the 278384RBR and the successor to the earlier 78384 reference, with the diamond bezel construction shared across all three generations.

• How many diamonds are on the Rolex 178384 bezel?

  The Rolex Datejust 178384 has 46 brilliant-cut diamonds set into the factory 18k white gold bezel in a single row around the perimeter. Each diamond is hand-selected and hand-set by Rolex gemologists at the factory, and the bezel itself is constructed in solid 18k white gold rather than steel because the gemstone setting requires the malleability of solid gold to securely hold each stone. The diamond bezel is a permanent factory configuration and cannot be removed or swapped, which is why the diamond bezel reference number (178384) is distinct from the smooth bezel reference number (178240) even though both share identical case, movement, and bracelet construction. Aftermarket diamond bezels are not factory original and significantly impact resale value and authentication, which is why every 178384 sold at WatchGuys is verified for factory-original diamond bezel construction by our in-house watchmakers.

• What is the difference between the Rolex 178384 and the 178240?

  Both are 31mm Datejust 31 references in identical Oystersteel case construction with the same Caliber 2235 movement and the same Oyster or Jubilee bracelet options. The only difference is the bezel. The 178240 has a smooth domed bezel in pure Oystersteel, giving the watch a clean, restrained, sportier profile. The 178384 has a factory 18k white gold bezel set with 46 brilliant-cut diamonds, giving the watch a dressier, more jewelry-forward presence. The diamond bezel construction also requires the bezel itself to be made of 18k white gold rather than steel because the gemstone setting requires solid gold malleability. The 178384 typically trades roughly $7,000 above the 178240 on the secondary market, which is the quantifiable value of the factory diamond bezel. The choice between the two comes down to whether the diamond bezel premium is worth the price for the desired aesthetic. Both share identical proportions, the same movement, and the same overall design language otherwise.

• What is the difference between the Rolex 178384 and the 278384RBR?

  Both are 31mm Datejust 31 references with the same factory 18k white gold diamond bezel set with brilliant-cut diamonds, in identical Oystersteel case construction with the same Oyster or Jubilee bracelet options. The difference is the production era and the movement. The 178384 was produced from approximately 2007 through 2018 and uses the Caliber 2235 with a 48-hour power reserve. The 278384RBR is the modern current-production successor introduced around 2018 and uses the updated Caliber 2236 with the Syloxi silicon hairspring, which offers improved magnetic resistance and a slightly extended 55-hour power reserve. The case proportions, dial menu, bezel construction, and overall styling are nearly identical between the two references, with the 278384RBR receiving minor refinements to the case and bracelet finishing. The 278384RBR typically trades $5,000 to $6,000 above the 178384 on the secondary market due to the newer movement and current-production status, putting the 178384 at the most accessible price point for a factory diamond bezel Datejust 31.

• What dial colors are available on the Rolex 178384?

  The Rolex Datejust 178384 was offered in the broadest dial selection of any Datejust 31 reference, with the diamond bezel construction giving Rolex room to pair the bezel with a wide range of dial styles. Mother of pearl variants include white mother of pearl Roman, black mother of pearl Roman, and mother of pearl diamond pave configurations, with the iridescent shell surface creating dynamic color shifts depending on lighting. Floral motif dials are available in silver, slate grey, and rhodium grey with raised floral patterns that catch light dramatically. Diamond hour marker variants pair multiple diamond placements with the diamond bezel for the most jewelry-forward configurations, including silver Jubilee diamond, full diamond pave, and feature variants with diamond-set VI markers. Standard configurations include black Roman, purple Roman with sunburst finish, and the highly collectible Goldust Dream Roman with its champagne metallic finish. Blue concentric Arabic and slate floral motif round out the most distinctive options. Most dial colors were available with either the Oyster or Jubilee bracelet in matching Oystersteel construction.
