The marker treatment is not a choice on most of this range. Across the whole Day-Date only five grounds are offered with both applied markers and Roman numerals, and every one of the five is neutral or metallic: white, silver, champagne, ice blue and chocolate. Every colored and every graded ground has its markers dictated. All four ombre dials take Roman numerals and nothing else. Bright black and slate take applied markers and nothing else. So the decision a buyer makes on this configuration, Roman rather than applied on a white ground, is one the model withholds almost everywhere else, and on this yellow gold reference white is the only dial that offers it at all.
Roman numerals in gold on a white ground is the oldest visual formula the model uses and the one that still reads as the most formal. The characters are applied rather than printed, tall and narrow with the serifs pulled fine, standing proud of the surface with polished faces that catch light at a different angle from the flat dial beneath. Their proportion is set by the diameter rather than by convention, reaching close to the minute track without crowding it, which is why the identical numerals in the 40mm case read as more spacious rather than simply larger. The ring is interrupted at three, where the date window takes the position a numeral would otherwise occupy, and the day arc at twelve sits above the numeral rather than displacing it. Against yellow gold the white ground does something specific: it isolates the numerals from the case, so the gold characters read as belonging to the dial rather than as an extension of the metal around it. The case is 36mm, the bezel is set with diamonds around its full circumference, and the President bracelet completes the watch in polished three-piece links. The numerals are solid applied characters rather than printed shapes, each fixed through the dial, and their edges are finished to a finer line than an applied baton requires, because a serif that reads as soft will show at arm's length where a plain marker would not.
Roman numerals cost something in speed and repay it in character, and the calendar is where that trade shows. Applied markers are read positionally, as points on a circle, and the eye takes the whole ring in at once; numerals are read as characters, which is fractionally slower and asks slightly more attention. On a dial with two apertures cut into the ring, that difference compounds, because the interruption at three has to be recognized rather than simply seen. What the arrangement gains is that the numerals and the calendar are doing the same kind of work. The day is spelled out in full at twelve in words rather than three-letter abbreviations, so the upper part of the dial already carries text, and Roman numerals extend that logic around the rest of the ring in a way applied markers do not. Both discs advance instantaneously at midnight rather than creeping through the preceding hour. The movement carries roughly seventy hours off a full wind, and everything is set through the crown, with no correctors interrupting the case band. That display runs under all eight grounds this reference builds, so the only variables are the surface and what stands on it. White is the one ground never offered with stones, and five of the remaining seven exist in set form alone, which leaves the plain face a narrow position at this reference.
Ten grounds are offered on yellow gold at 36mm and seven of them exist on this metal alone. Only white, mother-of-pearl set with diamonds and the paved dial travel outside it, and five of the ten can be had only as set dials, which leaves champagne, green ombre and white as the entire unset range on this case. Within that group of three, green ombre is Roman only and champagne appears here with applied markers, so white is the sole ground on the reference where the marker treatment is a live decision rather than a consequence of the ground. Three references carry the roster in full, 128238 with a fluted bezel, 128348RBR, which splits again on the bracelet, and this one, all with identical dials. A buyer therefore settles the ground, then the bezel, and on white alone gets a third question to answer. Roman numerals appear on exactly two of the ten grounds offered on this case. Green ombre carries them with no alternative, as every ombre in the range does, and white carries them alongside an applied-marker version of the same dial. So a buyer who wants Roman numerals on yellow gold at this size is choosing between a graded green dial and this one, and only this one leaves anything open afterward. That is a much narrower field than the roster count implies, and it is why white does more work on this metal than its plainness would suggest.
White with Roman numerals under a set bezel is a watch pulling in two directions, and it is bought by people who want the dial to hold the line. The numerals belong to the most conservative reading of the model and the bezel to the least, and the combination reads as a formal watch that has been deliberately complicated rather than as a decorative watch that happens to have a plain dial. Collectors tend to prefer this to the applied-marker version on the same case for exactly that reason: applied markers and a set bezel move in the same direction, while Roman numerals and a set bezel do not, and the friction is what makes the watch interesting to look at twice. It is also the most legible formal configuration the reference offers, since a white ground holds one value in every light and gold numerals against it never lose their edges. For a collector who wants a yellow gold Day-Date that can be worn to anything, this is the dial that does not need to be considered first.
