Seven grounds on this reference are offered set with diamonds and they split into two treatments with nothing to predict which. Bright black, bright blue and mother-of-pearl receive a plain ring of settings at the hour positions. Aubergine, dark grey, pink and silver receive that ring joined by gold Roman numerals at six and nine, themselves set with stones. Two dark grounds fall on opposite sides of the line, two colored grounds fall on opposite sides of it, and the neutral and the natural grounds are separated as well. Whatever governs the choice was decided per ground and is recorded nowhere. This variant is not among them: a white dial with a full Roman set and no stones anywhere, in a 36 mm case of steel and white gold, under a fluted bezel, on a Jubilee bracelet.
White is the only ground here that is never set at all. Every other dial on the reference is available with stones in one arrangement or another, and white is offered plain, with numerals or with applied markers, and in no set version at any point. The same holds at 28 mm, where the collection sets ten different grounds and leaves white alone. For a dial this widely distributed, reaching more references, sizes and materials than anything else the range makes, that is a conspicuous exclusion, and it means a buyer who wants white has already decided against a set dial by choosing the ground. The white gold of this construction sits in the fluted bezel, fluting never being cut into steel, and everything else is steel. The date sits at three under its magnifying lens, in the position the numeral would otherwise occupy. The Jubilee earns its place on a dial with nothing set on it. An unset white ground with applied numerals gives the eye a fixed and unchanging surface, so the watch depends on its metal for any sense of movement, and five-piece links divide the steel finely enough to supply it. Light crosses them in short intervals as the wrist turns while the dial holds still above, and the contrast between the two is what keeps a plain configuration from reading as flat. On the set dials elsewhere on this reference the calculation runs the other way, since those dials generate their own movement and a finer bracelet competes with it.
The plate carries a full Roman set anchored at every hour position around the aperture and nothing else, no piercing for settings and no second depth of fixing, so it retains more rigidity than any of the set dials on this reference. That matters on white in particular, since a bright even surface reflects continuously and shows any deviation beneath it as a faint band under raking light, where a dark or textured ground would conceal the same fault. The movement is self-winding and runs for roughly 70 hours away from the wrist, against close to 55 in the smaller cases, the difference being barrel volume in a physically larger movement. The date advances in a single step at midnight and the crown screws home when the watch is not being set. There is a further reason the numerals suit this ground at this size. A white dial at 36 mm presents a large expanse of even brightness, and a marker ring alone would leave most of it unstructured, which is why the collection withholds the marker version from every cool case at this diameter and offers it only on warm ones. The numerals divide the surface without darkening it, giving the eye a sequence to follow across ground that would otherwise be undifferentiated. That is a size-dependent argument, and it explains why the same treatment is the only option below 36 mm on every construction.
Being excluded from the setting is not the same as being a lesser dial, and on white it is close to the opposite. The ground goes everywhere: seventy-one references, eight case sizes, eight case materials, every bezel treatment the collection makes. What it does not do is vary. Below 36 mm it takes numerals and no alternative, above that it adds markers on warm cases only, and it is never set anywhere. A dial drawn once and left alone can be fitted to any case in the line without adjustment, and that is very likely why it reaches further than anything else while offering the fewest arrangements. Reading the exclusion alongside the reach is what makes the ground legible as a design decision rather than an oversight. A dial that is never set, never varied below 36 mm and never adjusted for the case it sits on is a dial intended to be a constant, and constants are what a range this large needs in order for its variations to mean anything. White is the fixed point everything else on this reference is implicitly measured against, and it could not perform that role if it changed from case to case.
The argument for this configuration is clarity. A white ground with gold Roman numerals is the most legible dial the reference makes, it belongs to no period, and the steel case keeps the watch from reading as formal. Collectors who choose it are usually buying something they intend to wear without thinking about, and often already own something more particular. The Jubilee keeps it comfortable across a day without adding ceremony. Among the arrangements this reference offers it is the one that will need the least explaining to anyone who sees it, now or in twenty years. It is also the version of this reference most likely to be bought without comparison, since a buyer who has settled on a white dial has already narrowed the field to one arrangement and has nothing left to weigh. That is worth stating plainly because it inverts how the rest of the reference works. Every other ground here presents a further decision once it has been chosen, whether about markers, about stones or about which of two treatments the case permits. White presents none, and the only question remaining is the bracelet.
