Two numerals on this dial are gold and set with diamonds, and the other ten are not. The arrangement puts stones into the Roman characters at six and nine while leaving the rest of the ring as plain applied numerals, so the dial carries setting at exactly two positions and nowhere else. It is a narrower intervention than any other set treatment the model offers, where stones usually replace the markers entirely or run through the whole ring, and it produces a watch that reads as unset until the eye reaches the vertical axis. On an olive green ground the effect is subtler still, since a muted color gives the stones less to reflect against than a dark or a pale one would.
The ground is a muted grey-leaning green, closer to a field tone than to anything bright, applied flat with no gradient and no metallic component beneath it. It reads as green under direct light and drifts toward grey-brown in shade, which is what lets it sit against a case combining steel and yellow gold without either metal dominating it. A saturated green would have fought the gold; this one negotiates. The numerals are applied in gold throughout, and at six and nine the characters are set with diamonds, which on a ground this restrained functions as punctuation rather than as decoration. The bezel is domed, smooth and entirely unadorned, so the only stones on the watch are the two on the dial. The case is 36mm and the Jubilee bracelet runs from it in five-piece links, articulating finely enough that the watch follows the wrist rather than sitting across it. Setting stones into a numeral is a different problem from setting them into a dial. A Roman character is narrow, and the stones have to follow its strokes rather than fill an area, so each one is small and the seats are cut along a shape that was designed to be read rather than to hold anything. What results is a numeral that still functions as a numeral, legible as a six or a nine at a glance, with the stones registering only afterward. That sequence is the point of the arrangement and it fails immediately if the stones are sized to be noticed first.
The date at three is all this model does beyond the time, and on a dial with numerals at every hour that single window has to displace one of them. The character at three gives way to the date and the ring is broken at one point, which the eye learns to expect quickly. There is no day aperture and no second indication, so the composition is emptier than the same case supports elsewhere in the catalogue and the numerals carry more of it. The date sits beneath a lens set into the crystal, magnifying the numeral without distorting the ground around it. A printed disc matches a muted flat green closely, since the color is low in both value and intensity and small discrepancies do not register the way they would against something saturated. The movement runs roughly seventy hours off a full wind and everything is set through the crown. The lens over the date is worth a word, since it is the one element on the watch that magnifies rather than reflects. It enlarges the numeral on the disc beneath without distorting the ground around the window, which asks something of the crystal, and it is the reason a Datejust can carry a date at all on a dial this size without the window dominating it. Everything else on the surface is read at its actual scale; the date alone is read larger than it is.
Olive green appears on this reference in four configurations, more than any other ground it carries: with Roman numerals, with applied markers, and with this set arrangement, each of those available on either bracelet. No other dial on 126203 is offered three ways. That is unusual for a color rather than a neutral, since the model normally reserves that latitude for white, champagne and silver, and it reflects how recently olive green entered the range and how widely it has been pushed since. Across the 36mm size the nine references divide by metal and bezel without repeating a combination, and a domed bezel is available on three of them, this one included. Olive green also reaches beyond this reference in its plain form while the set version stays narrower, which is the usual pattern: stones tend to restrict where a ground can go rather than extend it. Here the restriction is mild, since the arrangement uses the numerals that were already present rather than replacing them. A ground that loses reach when stones are added is the more common case in this range, and olive green escapes it only because the setting was designed into markers the dial was always going to carry.
The set numerals are the detail that decides this configuration, and collectors tend to have a firm view of them. Read one way they are the most tasteful way to put diamonds on a Datejust, confined to two positions and integrated into markers that would have been there regardless. Read the other way they are a half-measure, neither a plain dial nor a set one. What is not in dispute is that they survive daily wear better than a fully set dial does, since two stones catch light occasionally rather than constantly and the watch stays legible from any angle. Combined with a domed bezel and a muted ground, the result is a two-tone Datejust that carries diamonds and does not look like it does. The plain Roman version of the same dial sits alongside it on this reference for anyone who wants the ground without the stones at all.
