Day-Date › 1811

The 1811 in yellow gold with a blue dial: the Morellis (moiré) finish on the bezel and the President bracelet's center links

The 1811 is the Morellis-finish Day-Date. It uses the 36mm gold case and caliber 1555/1556 family shared with the fluted 1803, with a watered or moiré texture on the bezel and documented President bracelet center links. The finish places it with the decorated four-digit Day-Date references, including Florentine 1806 and bark 1807. Collector and auction descriptions use Morellis, moiré, and related terms; the reference number and construction remain the basis for attribution.

Where it sits in the line

The 1811 is one of the 1803's decorated siblings, the group that split the 4-digit Day-Date by surface finish, on a shared case and movement. The 1803 took the fluted bezel, the 1804 a gem-set bezel, the 1806 the Florentine cross-hatch, the 1807 the coarse bark, and the 1811 the Morellis moiré. Each carried its texture onto the bezel and, on the 1806, 1807 and 1811, onto the bracelet center links so the finish ran the length of the watch.

Collector and trade listings use both Morellis and moiré for the texture, and some listings conflate it with Florentine. The case, bracelet, movement, and dial should be assessed together; the 1803 entry covers the shared four-digit lineage.

Production outline

Documented 1811 examples date from the late 1960s and 1970s and use caliber 1555 or 1556. Rolex does not publish a production total or sales history for the reference. The textured finish is not the same as the bark treatment used on later references such as the 18078.

Movement notes

The 1811 uses the four-digit Day-Date movement family. Reference material places caliber 1555 before caliber 1556, with 19,800 vph on the later movement; hacking was added during 1556 production, but the exact fitment year is not a clean reference cutoff. Four-digit Day-Date references do not have a quick-set day/date mechanism. Exact fitment should be checked from the movement and case evidence. The Reference:Movements page holds the caliber lineage, and the 1803 entry covers the 1555-to-1556 transition in detail.

Dial map

The 1811 used dials from the four-digit Day-Date catalogue. Auction descriptions document champagne, silver, and special dial configurations, including a champagne dial described as Doorstop. Dial choice is shared across the group and is not, by itself, an 1811 identifier.

Case, bezel, crystal, and crown

The case is the 36mm three-piece gold Oyster shared across the 4-digit Day-Date, with a Twinlock screw-down crown, screw-down caseback and acrylic crystal. The defining feature is the Morellis finish on the bezel, a watered moiré texture distinct from the Florentine cross-hatch of the 1806 and the bark of the 1807. It came in yellow, white and pink gold to match the case.

Bracelets, end links, and clasps

Documented 1811 examples use President bracelets with textured center links. Service or replacement bracelets can have plain links, so original fitment should be checked against the bracelet, clasp, case, and provenance. A clasp date dates the bracelet, not the watch head.

Special branches

The decorated 4-digit references

The decorated four-digit group includes Florentine 1806, bark 1807, and Morellis 1811 treatments. Because the finishes can be confused or altered, attribution should use the reference number between the lugs, case construction, bracelet, and provenance.

Auction record

The cited auction records show individual configurations rather than a complete production total. Antiquorum sold a yellow-gold example in New York on 8 December 2016 (Lot 211): a 1967 piece, caliber 1556, satin silver dial, 36mm case on a President bracelet with textured center links, complete with its original Chronometer Certificate and booklet. The catalogue calls the bezel finish “moiré crosshatch,” supporting the Morellis name. It was estimated at USD 8,000–12,000 and sold for USD 17,500.

A second Antiquorum lot, Hong Kong, 28 May 2022 (Lot 211), catalogues a yellow-gold example from around the same period: case no. 1,672,343 by Genex of Geneva, caliber 1555, on a President bracelet the lot text describes as “hammered.” The catalogue also records the case as 1811/1601. Whether “hammered” and “moiré crosshatch” are two names for the same texture or indicate a sub-variant is not settled by these two lots alone. The estimate was HKD 95,000–144,000 and the result HKD 115,000.

The bracelet is part of the provenance and originality assessment in both lots; replacement or service links can change the configuration.

-The 1811 is the Morellis-finish Day-Date. It is a 4-digit President built on the same 36mm gold case and caliber 1555/1556 movement as the fluted [[Reference:1803|1803]], set apart by a fine watered texture, the moiré or "Morellis" finish, on the bezel and the President bracelet's center links. The finish belongs to the same late-1960s fashion for decorated gold that produced the Florentine 1806 and the bark [[Reference:1807|1807]]. The Morellis is the rarest and least-seen of the three, made in small numbers and easy to misread, which is why it turns up in listings under several different names.

-The naming is where the 1811 gets slippery. Collector and trade usage settles on "Morellis" for the watered moiré texture, while some listings call it Florentine and conflate it with the 1806. Everything else is 1803: the 36mm gold case, the President bracelet, the caliber 1555/1556 movement and the dial catalogue all carry over, and the [[Reference:1803|1803]] entry holds the full account.

 ==Production outline==
-The Morellis 1811 ran through the late 1960s and into the 1970s alongside the plain 1803, in small numbers. No Rolex production figure has surfaced, and like the other textured references it sold slowly when new, which makes it scarce today. Documented examples cluster in the late 1960s on the caliber 1555 and run into the 1970s on the caliber 1556. The decorated-finish references faded as taste returned to polished and fluted gold, and the texture did not carry into the 5-digit era the way the bark did on the [[Reference:18078|18078]].

 ==Movement notes==
-The 1811 uses the standard 4-digit Day-Date movement, caliber 1555 from the start of the run and caliber 1556 from around 1965. The 1556 raised the beat to 19,800 vph through a gear-train change, carrying over the free-sprung Microstella balance of the 1555; hacking seconds were added to the caliber mid-production in 1972. No 4-digit Day-Date has quickset, so date and day advance only by running the hands through midnight. The [[Reference:Movements]] page holds the caliber lineage, and the [[Reference:1803|1803]] entry covers the 1555-to-1556 transition in detail.

 ==Dial map==
-The 1811 carried the standard 4-digit Day-Date dials, champagne and silver with applied gold markers most common, and as a catalogue sibling of the 1803 it could take the same special dials. A champagne "Doorstop"-dial 1811 is among the documented examples. The Morellis finish is what defines the reference; dial choice is shared across the 4-digit group, and the [[Reference:1803|1803]] entry carries the variant taxonomy.

 ==Bracelets, end links, and clasps==
-The 1811 wears the President with the Morellis finish carried onto the bracelet's center links, so the moiré runs unbroken from the bezel down the length of the bracelet. As with any vintage President, a clasp date code dates the bracelet, which may be older or newer than the head, and the [[Reference:Bracelets]] page holds the cross-family bracelet detail. Decades of service often replaced textured center links with plain ones, so an 1811 that keeps its full original Morellis bracelet is the harder thing to find.

-The Morellis 1811 surfaces mainly through specialist dealers and rarely at the major auction houses, in line with its modest standing and small production.
