Rolex Datejust 41, slate Roman numeral dial

What the “Wimbledon” name actually refers to

The nickname is buyer-side shorthand. It is not a name the manufacturer gives the dial, and it is not a reference number; it is the label that has attached itself to the slate-grey Datejust dial with green-outlined Roman numerals, on account of the accent colour. Two practical points follow. If you ask for a “Wimbledon” dial you are describing a colour and marker treatment, so adding the reference number removes any doubt about which one you mean. And because the nickname travels separately from the catalogue, it does not identify a case size either — the same dial treatment has existed on more than one Datejust diameter, which is why the size on this page is given as a model figure rather than inferred from the name.

Green-edged Roman numerals on a slate background

Each Roman numeral is an applied element rather than a printed shape: a green outline around a lighter centre, standing slightly off the dial, with a reflective edge that catches light as the wrist turns. The slate background is finished with a radial brushing that runs outwards from the centre, so the same dial looks darker straight on and lighter at an angle. Eleven positions carry numerals; the twelfth is the date.

Under the numerals sits a fine minute track with small printed indices. That gives the outer dial two rhythms to look at — the wide, angular Roman forms above and the fine track beneath them — and it is why a photograph taken close to straight on is more informative than a wide shot: you can check that each numeral sits level on the track rather than floating above or clipping into it. Against the dark ground, the green outline is the strongest colour event on the watch.

The fluted bezel and the light it returns

A ring of repeating ridges surrounds the dial. Every ridge presents a slightly different face to the light, so the bezel alternates between bright and dark as the wrist moves — the visible signature of the design, and the reason one photograph rarely tells the whole story about it. Soft daylight and a small indoor lamp produce quite different results on the same bezel, so two frames taken at different angles are more useful than one perfectly lit frame.

This bezel carries no printed scale at all: no minute graduations, no rate scale. The model’s published specification describes the case and bezel combination as steel with white gold, and the bezel is the warmest-looking surface on the watch even though the overall impression is silver-tone. Colour alone cannot tell you what a supplied example is made from or whether a white-metal surface is solid, capped or plated; that question is one of the items in the inquiry.

The date window and the magnifier

The date sits at three o’clock under a raised magnifying lens, which makes the calendar a visual feature of the design rather than a small cut-out in the dial. The lens also changes how the date looks from different angles: the numeral inside the aperture is easiest to judge from close to straight on, and least reliable from a steep diagonal.

In a clear dial photograph three things are worth checking together — where the lens sits relative to the crystal edge, how the aperture is shaped, and whether the numeral is centred inside it. What no photograph of the outside can establish is how the date changes: the movement’s design decides that, and it belongs to the supplied watch, so it is asked about rather than assumed.

41 mm on the wrist, and what the number leaves out

The model’s case diameter is 41 mm. Two watches of the same diameter do not wear alike: the dial opening, the width of the bezel, the case thickness and the way the first links angle away from the case all change the impression on the wrist. A white-metal fluted bezel and a lightened dial also make this watch read warmer and busier than a black-dial sports watch of the same size in this collection.

If you already own a 41 mm watch, compare the dimensions you can measure rather than assuming the fit carries over. Diameter tells you the width of the case body; lug-to-lug length tells you how much wrist the watch occupies; thickness tells you whether it will sit under a cuff. Those are the numbers to ask for, and a wrist photograph is only useful alongside the wrist size it was taken on.

The five-link bracelet and how to name a combination

The bracelet is divided into five links across its width: three narrower centre links between two broader outer links, which produces a finer visual rhythm than the broad centre section of a three-link bracelet. Linked side by side with the fluted bezel, the two repeating patterns carry the same colour idea round the whole watch instead of concentrating it in one piece.

When you ask about a Datejust, name the three parts together — dial, bezel and bracelet — plus the case size and the reference. Stating them separately invites answers about different watches. If you want a different dial treatment or a bracelet in the other link pattern, say so in the same message; the collection shows a small number of configurations and the message is where a specific one is pinned down.
