The 218238 is the Day-Date II, produced for seven years from 2008 through 2015 on the cal 3156. The movement is the cal 3155 scaled up with a 2.5mm wider main plate to fit the 41mm Oyster case that the reference introduced. That 5mm jump from 36mm to 41mm is the single largest dimensional change in the Day-Date line since the 6510 launched in 1956. Same fluted bezel on yellow gold, same hidden Crownclasp on a President bracelet scaled to 41mm. The Day-Date II is also the shortest-run Day-Date reference in the modern era and the only 41mm Day-Date Rolex has ever produced. By Baselworld 2015 the Day-Date 40 (228xxx) had taken its slot at 40mm, splitting the difference between the 36mm classic and the 41mm Day-Date II.

==Where it sits in the line==

The 218238 is the 41mm experiment in the Day-Date line. Rolex pushed it out at Basel 2008 as the late-2000s response to the broader luxury-watch shift toward larger dress watches; Patek, Audemars Piguet, and Vacheron had already pushed dress watches past the 38mm ceiling that had defined the category through the 1990s. The Day-Date II launched alongside the Datejust II as a coordinated 41mm-plus pairing. The Datejust II ran longer. The Day-Date II discontinued after seven years and Rolex split the difference with the 40mm Day-Date 40 (228xxx) from 2015.
The 218238 appeared at Baselworld 2008 alongside the Datejust II, during a period when Rolex was offering larger cases across several lines. The Day-Date II ran for seven years; in 2015 Rolex replaced it with the 40mm Day-Date 40 (228xxx).


Every Day-Date before and after the 218238 sits at either 36mm (1803 through 118238, then 128238 from 2019) or 40mm (228 series from 2015). The 5mm case jump and the seven-year run combine to make the 218238 the most divisive Day-Date in the modern catalogue. Early-launch press read the proportions as overstated, with aBlogtoWatch calling the case "chunky" and the bezel "conspicuously wider than before"; the post-discontinuation collector market has read the same proportions as distinctive and the 218238 as a future-classic candidate.
Every Day-Date before and after the 218238 sits at either 36mm (1803 through 118238, then 128238 from 2019) or 40mm (228 series from 2015). Early launch coverage questioned the larger proportions; aBlogtoWatch called the case "chunky" and the bezel "conspicuously wider than before." The 40mm successor uses slimmer lugs and a thinner bezel.


The movement is the cal 3156, the cal 3155 architecture scaled up. The base plate measures 28.50mm and the overall main-plate dimension runs 30.97mm, 2.5mm wider than the 3155. That dimension is the architectural reason the movement exists. The 3156 was also the first Day-Date caliber to ship with both the Parachrom Blu hairspring (rolled out across Rolex from approximately 2005 but only universal on Day-Date from the 218238) and the Paraflex anti-shock system. The successor cal 3255 on the Day-Date 40 jumps the power reserve to approximately 70 hours across 14 patents.

Seventeen distinct dial codes are documented across the family, the most exhaustive specific-dial roster published for the 218 generation.
Seventeen distinct dial codes are documented across the family in the sources reviewed here. The list is not complete: Bonhams has separately catalogued an 18k white gold 218239 with a rhodium charcoal-grey dial outside those 17 codes.


There is no 218389 Tridor in the catalogue. Rolex discontinued the Tridor (tri-tone gold President) around 2000 with the 18239B closeout; no Tridor 218xxx appears in the auction record or in any published reference listing. The modern-reference numbering scheme (last digit indicating metal: 8 yellow, 9 white, 5 Everose, 6 platinum) doesn't support a 218389 slot either. There is also no 218339 white-gold-diamond reference. The diamond-bezel white-gold 218xxx is the 218349; dealer listings citing "218339" are typos for 218239 or 218349.

The cal 3156 carries 31 jewels, runs at 28,800 vph (4 Hz), holds approximately 48 hours of power reserve, and is COSC chronometer certified to the pre-2015 ±4 / +6 seconds per day standard. Double quickset advances day and date independently via the crown, the seconds hack, and the balance is the standard Glucydur with Microstella weight screws. The base plate measures 28.50mm, with a 30.97mm overall main-plate dimension that runs 2.5mm wider than the cal 3155.

Two firsts for the Day-Date line landed on the 3156: the Parachrom Blu hairspring, which arrived across the Rolex catalogue from approximately 2005 but only became universal on Day-Date with this caliber, and the Paraflex anti-shock system. The 3156 retired in 2015/2016 with the Day-Date II discontinuation. The Day-Date 40 successor stepped to the cal 3255 with 14 patents, 70-hour power reserve, Chronergy escapement, and Superlative Chronometer ±2-seconds-per-day certification. The cal 3156 sits as the bridge between the 3155 architecture of the 118238 era and the cal 3255 modern era.

41mm Oyster, 21mm lug width, 49mm lug-to-lug. Thickness reports range 11.9mm to 13mm depending on whether the measurement is at the midcase or over the caseback boss. Water resistance is 100m. Total weight on the 18k yellow gold 218238 head plus full President bracelet runs approximately 220g. The platinum 218206 weighs materially more; the platinum head and bracelet drive the total roughly 30 percent above the gold variants.

===Bezel===
===Bezel===


The 218 generation runs four factory bezel configurations. The fluted bezel sits on yellow gold (218238), white gold (218239), and Everose (218235) and continues the default Day-Date format since the 1803 era. The smooth domed bezel is reserved for the platinum 218206; it is Rolex's traditional platinum format and a strong identifier from across the room, and the 218206 is the only 218 production-volume reference to wear it. Factory diamond bezels appear on 218348 (yellow gold) and 218349 (white gold), set with round-brilliant diamonds in the bezel ring. The Datejust II's fluted-with-aftermarket-diamond range does not apply here; aftermarket gem-setting on a 218238 is identifiable through stone-cut and prong-style inconsistencies against the factory work.

Champagne Roman is the production-volume dial on the 218238 yellow gold, the default configuration in the secondary market and the dial collectors picture when they hear the reference. White Roman and black Roman round out the standard yellow gold trio.
Champagne Roman is a standard 218238 yellow-gold dial. White Roman and black Roman are also documented on the reference.


Chocolate dial with Roman markers is the signature dial for the Everose 218235 (-0035) and white gold 218239 (-0040), a 218xxx-era introduction that became a Day-Date marker. Chocolate paired with diamond markers on Everose pushes well past the base price.

The platinum 218206 carries the ice blue dial, which is platinum-exclusive across the entire Rolex catalogue. The signature is not a 218xxx invention but it was cemented on this reference. Ice blue appears in three forms on the 218206: Roman (-0043), Arabic (-0010), and diamond Roman (-0052). The concentric-circle reading on the periphery, with darker-blue Roman numerals and matched hands, is the most-photographed configuration. Platinum also offered black Arabic (-0003), black diamond (-0020), silver diamond (-0009), and white Roman (-0053).

Factory pavé in the 218 line surfaces on 218206-0052 (platinum diamond Roman) and 218235-0008 (Everose pink diamond). The factory-set ruby-and-diamond baguette champagne dial 218238 is one of the rarest configurations and trades in the high USD 50,000 range against USD 30,000–39,000 for the standard yellow gold 218238. Factory diamond hour markers appear on both the 218348 (yellow gold) and 218349 (white gold) alongside their diamond bezels. Production volume on the diamond-bezel siblings is small relative to the standard fluted-bezel references, and surfaced examples trade above USD 80,000.

The standout 218 generation auction lot is the Day-Date II Royal Khanjar reference 218206, a platinum diamond-set example with Arabic day-and-date discs commissioned for the Sultan of Oman around 2012 and engraved on the caseback with the Royal Khanjar crest. Sotheby's catalogued the lot in their 2025 Origins sale and again in Important Watches Part I (GE2504). Bonhams has separately catalogued and sold a production-spec 218206 platinum c. 2010. Phillips coverage of the reference is thinner; Day-Date II auction interest concentrates on the special-order and commissioned platinum examples rather than gold production lots, which trade primarily on the secondary market.

The 218238 itself has a direct auction result: Bonhams sold an 18k yellow gold example at its December 2017 Fine Watches and Wristwatches sale in London for GBP 18,750 including premium. Sunburst champagne dial with applied luminous baton markers, cal. 3156, President bracelet, complete with its original Rolex box, outer card, guarantee, and brochure — the watch was originally sold by Rolex on 23 September 2010. Sotheby's has separately listed an 18k yellow gold 218238 with a champagne diamond-set dial through its Buy Now marketplace at USD 41,500, box and papers included; that is a fixed-price listing rather than a competitive auction result, but it corroborates the factory diamond-dial configuration.
 
The white gold 218239 has surfaced at Bonhams with a dial not on the 17-code roster documented above: a rhodium charcoal-grey dial, sold through Bonhams' Luxury Online sale for HKD 281,600 including premium. The white gold factory-diamond 218349 has also crossed the block at Bonhams, an example with diamond-set bezel and hour markers estimated GBP 20,000–30,000 at a December 2024 London sale.

Market bands across 2025–2026 cluster by metal. The yellow gold 218238 trades from approximately USD 27,000 to 55,000 depending on dial and provenance, with an average asking price near USD 38,000. The Everose 218235 runs USD 37,000 to 46,000 and above, with chocolate dials commanding a premium over ivory and black. The platinum 218206 sits between USD 50,000 and 90,000, the ice blue dial pulling the top of the band. The factory diamond-bezel 218348 and 218349 routinely cross USD 80,000.

The 218 generation has appreciated steadily post-discontinuation. The Day-Date 40 successor (228238) has appreciated roughly 30 percent over the last five years on aggregated market data, and the 218238 has tracked that arc on the discontinued-supply premium. The 218238 reads less as a value reference now than as a future-classic candidate with the discontinued-only-41mm-Day-Date framing carrying the case.
The available market data shows different asking ranges by metal and dial, but it does not establish a reliable long-term price trend for the 218238. The reference was discontinued in 2015; later market comparisons should be treated as time-specific observations rather than a forecast.

==Production timeline==


The 218238 launched at Baselworld 2008 alongside the Datejust II at a USD 27,650 MSRP for the base yellow gold and USD 30,150 with the 8 round + 2 baguette diamond dial. Rolex rolled out the random scrambled serial system catalogue-wide in 2010, and the 218238 production straddles the rollover. Late G-serial examples and random-serial post-2010 examples both surface in the secondary market through approximately 2012. Around 2012 Rolex executed the Sultan of Oman Royal Khanjar 218206 platinum commission, the caseback engraved with the Royal Khanjar crest. Baselworld 2015 brought the discontinuation: the Day-Date 40 (228xxx) launched at 40mm, replaced the Day-Date II 41mm outright, and continued the 36mm 118238 line until that line's own discontinuation in 2019.
