The 18238 is the Day-Date that finally became easy to set. It took over from the [[Reference:18038|18038]] in 1988 and kept the same 36mm yellow-gold President, the same fluted bezel and sapphire crystal, but swapped in the caliber 3155. That movement added the one thing the line had never had: a quickset for the day as well as the date, both indexed from the crown. For the first time an owner could correct a stopped Day-Date in seconds instead of winding the hands through midnight twice. The 18238 ran until about 2000, when the 6-digit [[Reference:118238|118238]] replaced it.

==Where it sits in the line==

The 18238 is the second of the three sapphire-crystal President generations. The [[Reference:18038|18038]] brought sapphire and quickset date to the 36mm Day-Date in 1977 on the caliber 3055. The 18238 follows in 1988 with the caliber 3155 and double quickset. The 6-digit [[Reference:118238|118238]] takes over around 2000 with the same 3155 movement in a redesigned case with the Cyclops-free crystal and solid-link bracelet. The 18238 is the bridge between the vintage-derived 5-digit Presidents and the modern 6-digit ones, and the cheapest way into a sapphire-crystal President that still wears the slim 1803-era case.

The catalogue splits the 3155 generation by bezel and metal the way the 18038 family did. The 18238 is the yellow-gold fluted reference and the volume seller. The 18248 carries a factory diamond bezel, the 18239 and 18249 are the white-gold fluted and diamond versions, and smooth-bezel and platinum variants round out the generation. Pink gold stays absent at this spec, returning only with the 6-digit Everose references. The full bezel-and-metal taxonomy carries over from the [[Reference:18038|18038]] entry.

==Production outline==

The 18238 ran for roughly twelve years, one of the longest single-reference runs in the Day-Date catalogue. Across that span the only running change of note is the lume. Early examples carry tritium, marked "T SWISS MADE T" at the foot of the dial; the latest examples, near the 2000 handover to the 6-digit line, switch to Luminova without the tritium designation. No quartz, no case change, no movement change inside the reference: the 18238 is a stable, single-spec watch for its whole run, which is part of why it trades as a dependable known quantity rather than a variant hunt.

Serial numbers track the standard Rolex stream for the period, running through the letter-prefix series of the 1990s. The reference overlaps the start of the 6-digit era briefly before giving way to the 118238.

==Movement notes==

The caliber 3155 is the 18238's reason to exist. It keeps the 28,800 vph rate and roughly 48-hour reserve of the 3055 and adds the day quickset, so both the day disc and the date wheel index from crown position two. The earlier 3055 quickset the date only; the day still had to be advanced by running the hands. The 3155 closes that gap and becomes the long-serving modern Day-Date movement, carried forward unchanged into the 6-digit 118238. The 31-jewel, COSC-certified 3155 also underpins the Day-Date II caliber 3156 that follows in 2008. The full caliber lineage sits on [[Reference:Movements]].

==Dial map==

The 18238 was offered across the standard President dial range: champagne and silver with applied gold markers as the volume choice, Roman-numeral and diamond-hour-marker dials, mother-of-pearl, and the occasional stone or special-order dial. By the 1990s the wilder Stella lacquer and Stern Frères stone dials of the 1803 era had largely given way to more restrained options, so a special-dial 18238 is scarcer than a special-dial 1803. The dial does not define the reference; for the deep dial-variant taxonomy that spans the President line, the [[Reference:1803|1803]] entry carries the full account.

==Case, bezel, crystal, and crown==

The case is the 36mm three-piece yellow-gold Oyster the President has used since the 1803, here with a sapphire crystal and the fluted bezel that is the Day-Date signature. The Twinlock screw-down crown gives 100m of water resistance. Nothing about the case dimensions changed from the 18038; the 18238 keeps the slim profile that separates the 5-digit Presidents from the slightly thicker 6-digit cases that followed.

==Bracelets, end links, and clasps==

The 18238 wears the President bracelet, reference 8385, with the concealed Crownclasp that hides the buckle under a flip-up crown medallion. The bracelet is solid 18k gold and integral to the watch's wrist feel. As with any President, a clasp date code dates the bracelet rather than the head, and the cross-family bracelet detail sits on [[Reference:Bracelets]].

==Special branches==

===The 3155 generation siblings===

The 18238 anchors a generation that splits by bezel and metal: the diamond-bezel 18248, the white-gold 18239 and 18249, and the smooth-bezel and platinum variants. They share the caliber 3155 and the sapphire-crystal President case, and differ only in finish and material the way the 18038 family did before them. The diamond and white-gold versions are scarcer than the yellow-gold fluted 18238; the platinum variant is the rarity of the group.

==Auction record==

The 18238 is a liquid, well-understood watch rather than an auction-record reference. Plain champagne and silver examples trade as the accessible entry to a gold President; the value moves with metal, dial, and the condition of the soft 18k gold case and bracelet, which wear and stretch with use. Diamond-bezel 18248s, special dials, and full sets with box and papers carry the premiums. Because the run is long and the spec stable, condition rather than rarity sets price across most of the reference.
