The 1806 in pink gold: Florentine finish on case and bezel, on the flat brick-link bracelet

The 1806 is the Florentine-finish Day-Date reference. The finish is a cross-hatch engraving on the bezel, case, and lugs; documented examples also use a matching flat brick-link bracelet. It shares the 36mm gold case, caliber 1555/1556 family, and dial catalogue with the fluted 1803. The finish and bracelet configuration are the identifying features.

Where it sits in the line

The 1806, 1807, and 1811 use different decorative treatments documented on four-digit Day-Date cases and bracelets. On the 1806, intersecting engraved lines cover the bezel, case flanks, and lugs; the 1807 has bark texture and the 1811 has Morellis-style texture. Attribution should start with the reference number and case construction, not finish alone.

The 1806 shares the 1803's 36mm gold case, caliber 1555/1556 family, non-quickset calendar, and four-digit dial catalogue. The finish and bracelet are the points that need separate inspection; the 1803 entry covers the shared platform.

Production outline

The 1806 appears alongside the 1803 in documented examples from the early 1960s through the 1970s. Rolex does not publish a production total for the reference. The cited watches span caliber 1555 and 1556 examples; case, movement, and bracelet should be checked on each watch.

Movement notes

The 1806 uses the 4-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. The exact fitment year should be checked from the movement and case evidence. The Reference:Movements page holds the caliber lineage; the 1803 entry covers the 1555-to-1556 transition.

Dial map

The 1806 uses dials from the four-digit Day-Date catalogue. Auction and specialist records document Stella and other dial configurations, but dial choice is not unique to the 1806; the individual dial and its provenance need inspection.

Case, bezel, crystal, and crown

The case is the 36mm gold Oyster shared across the 4-digit Day-Date, with a Twinlock screw-down crown, screw-down caseback and acrylic crystal. The gold itself is what changes. The Florentine cross-hatch covers the bezel, the case flanks and the lugs in fine intersecting engraved lines, and the reference came in yellow, white and pink gold.

Bracelets, end links, and clasps

Documented 1806 examples use a flat brick-link bracelet finished to match the case. The bracelet appears to have been an option or special order; original fitment should be supported by the bracelet, case, clasp, and provenance. A President bracelet on an 1806 requires the same check because replacement or reconfiguration is possible. A clasp date dates the bracelet, not the watch head.

Special branches

The decorated 4-digit references

The decorated four-digit group includes the Florentine 1806, bark 1807, and Morellis 1811. Because finishes can be altered or confused, attribution should use the reference number between the lugs, case construction, bracelet, and provenance. A matching brick bracelet is part of the individual configuration, not a universal requirement.

Auction record

Antiquorum and Christie's have catalogued individual 1806 examples with Florentine casework and brick bracelets. Auction and dealer descriptions show different dial, metal, and bracelet configurations; they do not establish a current price hierarchy. Bracelet originality and service history should be assessed with each watch.
