Rolex Day-Date 18049

A checked version of this page, approved on 10 August 2026, was based on this revision.

Day-Date -> 18049

The 18049 is the white-gold diamond-bezel Day-Date of the sapphire-crystal era, the 5-digit continuation of the gem-set 1804 and the white-gold counterpart to the yellow-gold 18048. Case, movement and bracelet are the 18039; the factory diamond bezel is what changes. It ran from the late 1970s to 1988 on the caliber 3055. Where a yellow-gold diamond Day-Date is a familiar object, the white-gold version reads almost as steel until the bezel catches light, and it appears at the major houses far less often than the 18048 does.

Where it sits in the line

The gem-set thread runs 1804, then 18049, then the caliber-3155 references. In the 5-digit generation Rolex split the diamond bezel by metal, and the closing digit carries it: 18048 in yellow gold, 18049 in white, 18046 in platinum. Phillips stated the rule outright in a catalogue essay on a white-gold bark example, noting that the final 9 indicates 18k white gold.

Behind the bezel there is no difference between an 18049 and an 18039: the same 36mm white-gold Oyster, the same caliber 3055 with quickset date only, the same sapphire crystal and President bracelet. The 18038 entry holds the generation's shared mechanical account, and the 18048 entry covers the diamond-bezel branch in yellow gold. What the 18049 offers over its yellow-gold sibling is discretion, which sounds contradictory on a diamond-set watch and is exactly why the combination has a following.

Production outline

The reference belongs to the 180XX group that replaced the 4-digit Day-Dates from 1977, bringing sapphire crystals and the caliber 3055, and it ends in 1988 with the arrival of the caliber 3155. Documented case numbers place surviving examples across the middle of that span: 6,654,074 on a circa-1981 example catalogued by Christie's, and 8,272,377 on a circa-1984 example catalogued by Antiquorum.

The 18049 is thinly represented in the major-house record. Two well-catalogued lots carry most of what can be said about it with confidence, against the much larger body of yellow-gold 18048 material, and no Rolex production figure has surfaced for either. The reference was a catalogue option rather than a limited edition, so the scarcity is relative — white gold simply sold in smaller numbers than yellow.

Movement notes

The 18049 runs the caliber 3055: 27 jewels, 28,800 vph, hacking seconds, a free-sprung Microstella balance and chronometer certification, with quickset on the date and nothing on the day, which still has to be advanced by running the hands through midnight. It is the same movement Rolex fitted to every reference in the generation regardless of metal or bezel. The Reference:Movements page holds the caliber lineage and the 18038 entry covers the 3055 in detail.

Dial map

The diamond bezel is the constant; the dial is where individual watches separate. The catalogued configurations pair diamond hour markers with a light ground: Christie's sold a circa-1981 example with a silvered dial, diamond hour markers and the Omani Khanjar emblem, and Antiquorum a circa-1984 example with a salmon-to-caramel dial and diamond indexes. Both are gem-set dials on a gem-set case, which is the reference's default expression rather than an upgrade.

Dial originality carries more weight here than on a plain reference. Diamond dials and diamond bezels are straightforward to fake or to add later, and on a gold case with factory stones the aftermarket versions circulate freely. Rolex paperwork, hallmarking and the evenness of the setting do the work; a documented service history from an authorised agent, as on the Christie's example, is worth more than any single visual test. The wider dial taxonomy for the President line sits on the 1803 entry.

Case, bezel, crystal, and crown

The case is the 36mm white-gold Oyster shared across the 5-digit Day-Date, with a screw-down caseback, a Twinlock screw-down crown and a sapphire crystal with Cyclops. The bezel is factory diamond-set, replacing the fluting of the 18039. The catalogued examples are described as diamond-set without a published stone count, so a number counted off a photograph settles nothing on its own; proportion, matched table size and the quality of the seats are the better read, alongside papers.

Bracelets, end links, and clasps

The 18049 wears the white-gold President bracelet, reference 8385, with the concealed Crownclasp and the solid links of the 5-digit era. A clasp date code dates the bracelet, not the watch head, and the cross-family detail sits on Reference:Bracelets.

One documented white-gold diamond-bezel example has surfaced on a President with bark-finish centre links, a bracelet type otherwise associated with the 18079. A single listing is a lead on fitment rather than evidence of factory delivery, and a bracelet swap over four decades is the simpler explanation.

Special branches

The Omani Khanjar

The strongest documented 18049 is a Gulf commission. Christie's catalogued a circa-1981 white-gold example with a diamond bezel and a silvered diamond-index dial carrying the Khanjar, the crossed-daggers-and-belt emblem of the Sultanate of Oman, sold in the house's Dubai online sale in 2023 accompanied by an Asprey & Co. presentation box and a Rolex service card issued by Khimji Ramdas in Muscat. Asprey of London and the Muscat distributor Khimji Ramdas are the two names that recur across the Omani Day-Dates of the period, and the same pairing appears on the 18038 and the 18048. The service card and the presentation box are what lift this example above the usual Khanjar attribution problem, since the emblem itself is among the most frequently faked features on a vintage Rolex dial.

Auction record

The record is short and the two anchor results are far apart. Christie's sold the Khanjar example in 2023 for USD 52,920 against a USD 40,000–60,000 estimate, and Antiquorum sold the salmon diamond-dial example in Hong Kong the same year for HKD 143,750 within its estimate. The gap is provenance rather than condition: a documented Omani commission with its Asprey box is a different object from a well-preserved catalogue watch. Standard white-gold diamond-bezel examples without a special dial or a paper trail trade below both figures, roughly in line with the yellow-gold 18048, and original factory gem-setting is the value driver throughout.
