Of the fully set configurations on this reference, this is the one built for legibility. Reference 128345RBR is the 36mm Day-Date in Everose gold with a factory diamond-set bezel, and here that bezel and a diamond-set President bracelet enclose a silver sunray dial whose hour markers are baguette-cut diamonds. Everything on the watch above the case flank carries stone, and yet the dial reads cleanly at a glance, because a bright neutral field with hard rectangular markers is the one combination that survives being surrounded by that much light. Silver is one of three grounds at this reference that take ten baguette cuts, alongside blue-green and mother-of-pearl.
The 36mm case is Everose gold, the alloy Rolex developed in 2005 so its copper content holds the pink tone permanently rather than fading toward yellow as conventional rose gold does. Diamonds replace the fluting on the bezel, and the President bracelet is set as well, which is the harder of the two operations because the links flex continuously in wear and each stone must survive that, making factory-set bracelets far rarer than set bezels and bracelet setting the component where aftermarket work most often fails. The silver dial is a sunray, brushed radially from the center so it moves from near-white at one angle to a soft grey at another, and that movement is what stops it reading as a flat panel between two bright bands. The markers are baguette-cut diamonds, cut as stepped rectangles rather than brilliants, returning light in broad flat planes instead of scattering it. On a light dial that geometry matters more than on a dark one: a round brilliant against silver reads as a bright patch with no defined edge, while a baguette holds a clean outline and functions as a marker rather than as ornament. The day is at twelve, the date at three beneath a magnifying lens, and the clasp is a concealed folding Crownclasp. A silver sunray carries no color to disguise an inconsistency in the brushing, and surrounded by diamonds on the bezel and the bracelet it has to hold against far more reflected light.
Two indications and nothing more: a day of the week spelled in full and an instantaneous date, with secure rapid-setting for both and a stop-seconds function for exact time setting. That has been the whole of the Day-Date since 1956, when it became the first wristwatch to show the day as a full word, a display requiring a larger disc than existing calendar architectures could hold and around which the movement was built rather than adapted. Both indications change instantaneously at midnight rather than dragging through the transition over several minutes. Day discs are available in a wide range of languages and fixed per watch at manufacture rather than user-selectable, making the language a permanent characteristic of the piece. Setting runs through a screw-down crown with a double sealing system, with no correctors on the case flank and nothing needing a tool. The self-winding movement holds approximately seventy hours of power reserve, so both calendar indications survive a weekend off the wrist. Eleven grounds are built at this reference and the specification does not change beneath any of them, so the ground and its markers carry the whole of the difference. Rolex cuts each seat directly into the dial and grades the stones so all of them return light at the same intensity.
Silver has been among the Day-Date's core dial options since the model's earliest years and has run continuously across every metal the watch has been offered in. Diamond markers on silver dials are nearly as old, appearing as standing catalogue options from the 1960s rather than as modern jewelry variants. Baguette settings are a later development and remain the less common of the two marker treatments, produced in smaller numbers because the cut wastes substantially more of the rough stone and because matching a full set for color, clarity and dimension is a harder sourcing problem than matching brilliants. Within the Everose gold 36mm range this is the fully set silver configuration of the 128345RBR, above the same dial on a plain bracelet and above the fluted-bezel 128235. Baguettes waste considerably more of the rough stone than brilliants, because the finished rectangle does not follow the crystal's natural shape, and matching a full set for color, clarity and dimension across one dial is a sourcing problem before it is a setting one. Setting the President is the hardest work on the watch and the component where aftermarket setting most often fails, so establishing that a set bracelet is factory work is the first thing worth checking.
This appeals to collectors who want the setting without giving up a watch they can read. Among fully set Day-Dates that is a narrower proposition than it sounds, because most configurations at this level put a paved, stone or strongly colored dial at the center and accept that legibility is not the point. A silver dial with baguette markers refuses that trade. It suits buyers making a first purchase at this level of setting who want something wearable rather than ceremonial, and established collectors who already own paved and stone-dial versions and want the one that behaves normally. The baguette markers are the reason it works. One further point is worth recording, and it concerns the sunray finish under full setting. A silver sunray carries no color to disguise inconsistency in the brushing, and surrounded by diamonds on the bezel and bracelet it has to hold against considerably more reflected light than it would on a plain-bezel watch. The finish is doing more work here than anywhere else in the range. Maximum setting on the case with minimum expression on the face reads as a contradiction on paper and resolves in the metal.
