The sapphires on this dial are the only stones in the Day-Date range that are not diamonds, and the metal they are fitted to changes how the sequence reads. The markers run through the spectrum, so one half of the ring is warm and the other is cool, and on an Everose case the warm half agrees with the metal while the cool half opposes it. On platinum the relationship inverts. On yellow gold the warm end merges almost completely. The dial itself is identical in every metal, since the ground is paved edge to edge and no case color reaches it, which means the only thing that differs across the four references carrying this configuration is which half of the spectrum is working with the watch and which half is working against it.
A paved dial has no ground in the ordinary sense. Stones are set across the entire surface in staggered rows, graded down in size toward the openings and the middle so no channel of metal shows between them, and the result behaves as one textured field rather than as a set of individual settings. Nothing of the Everose beneath comes through, which is why the dial is neutral in a way no other ground on this reference is: the eisenkiesel, the aventurine and the brown ombre all take something from the case, and this one takes nothing. Against that field the sapphires read as blocks of saturated color rather than points of light, cut as long stepped rectangles and laid flat so they return light in broad planes. The progression around the hour ring is continuous enough that the eye follows it as a gradient instead of counting stones. The bezel is set with diamonds around its full circumference, the case is 36mm in Everose gold, and the President bracelet runs from the lugs in polished semi-circular links. Grading is where a paved dial is judged, and the sapphires add a second axis to that judgment. The diamonds step down in size toward the openings and the middle, and the steps have to be small enough that no row reads as a change in scale. The sapphires must satisfy the same size discipline while also being matched for tone and saturation across a continuous progression, so a stone that is the right size but slightly off in hue cannot be used, and neither can its opposite. Those two requirements together narrow the usable stones considerably.
On a surface covered entirely in stones the calendar frames are the only straight lines on the dial, and they end up organizing a composition that has no other structure. Everything else is curved, faceted or graded. The day arc at twelve and the date window at three are fixed in position across the whole model, which also fixes the orientation of the sapphire ring around them, so the sequence always begins and ends in the same relationship to the two openings rather than being rotated to suit a particular reference. The day is spelled out in full rather than abbreviated to three letters, which is what the model exists to do and what makes the upper opening as wide as it is. Both discs change instantaneously at midnight rather than turning through the preceding hour, and the movement runs roughly seventy hours off a full wind. Nothing else on the watch requires attention. That is true of all eleven grounds at this reference, from the plain white through to the paved dial here, so the mechanical picture is the same wherever a buyer lands. What separates the configurations is the marker treatment, and the reference carries four of them across those eleven grounds, with only one ground offered in more than a single arrangement.
Twelve grounds are offered on Everose at 36mm and seven exist on this metal alone, leaving white, mother-of-pearl set with diamonds and the paved dial as the three that reach all four case metals. All three are colorless, which is exactly why they travel, but they are not equivalent. White is a manufactured finish and looks the same everywhere. Mother-of-pearl takes on the tone of whatever surrounds it. The paved dial is the only one of the three that is genuinely unaffected by its case, because the stones cover the surface completely and there is nothing left for the metal to influence. Three references carry the Everose roster: 128235 with a fluted bezel, 128345RBR with a diamond-set bracelet available on top of the bezel, and this one, which takes the set bezel and stops there. The paved dial also behaves across the two sizes in a way no other ground does. At 36mm it carries the sapphires on every metal, with no diamond-marker version available anywhere. At 40mm the sapphires are gone and the paved ground takes baguette diamonds instead, on Everose and yellow gold only, while platinum and white gold at that size receive a separately listed paved ground with sapphires set into it. The markers are decided by the case size rather than offered, and the sapphire treatment does not simply stop at the larger diameter but relocates into a different ground on a different pair of metals.
This is the configuration for a collector who wants the paved dial and wants the case to matter anyway. On a specification sheet the four metal versions are the same watch; in the hand they are not, because the sapphires and the case are having a different conversation in each one. Everose is the most interesting of the four for that reason, since rose gold sits between the warm and cool halves of the sequence rather than at either end, and neither half of the ring resolves comfortably against it. Whether that reads as tension or as incoherence depends on the buyer, and it is worth seeing before deciding. What is not in question is the difficulty of the work: matching colored stones for tone and saturation across a continuous progression is a harder problem than setting a field of white ones, and it is visible in exactly the place a collector will look first.
