The Rolex Day-Date is Rolex's most prestigious classic watch. It was the first wristwatch to show the day of the week spelled out in full, it is made only in gold or platinum, and it is usually worn on the bracelet created for it: the President.
If you are considering one, the main decisions are the size, the metal, the bezel and the dial. This guide explains each of them, how to read a Day-Date reference, and what to check before you buy.
By the numbers: Morgan Stanley and LuxeConsult estimate Rolex's 2023 sales at CHF 10.1 billion, a retail market share of just over 30% and more than the next five luxury watch brands combined. Rolex does not publish its own figures, so these are analysts' estimates (swissinfo.ch, 14 March 2024).
A short history
Rolex introduced the Day-Date in 1956. Next to the date window at 3 o'clock, it displays the day of the week spelled out in full in an arc at 12 o'clock. The President bracelet, with its semi-circular three-piece links, was introduced with it.
From the start, the Day-Date was made only in precious metals, never in steel. That is still true today.
Day-Date 36 or Day-Date 40?
| Day-Date 36 | Day-Date 40 | |
|---|---|---|
| Case | 36 mm | 40 mm |
| Current references | 1282xx | 2282xx |
| Movement | Caliber 3255 | Caliber 3255 |
| Power reserve | About 70 hours | About 70 hours |
| Character | Classic size, elegant on most wrists | Modern size, more presence |
The Day-Date 40 was introduced in 2015, with the then-new caliber 3255. The current generation of the Day-Date 36 uses the same caliber. Mechanically they are the same watch; the choice is about size and proportion.
How to decide: the 36 mm is the traditional size and sits close to the wrist; on a gold watch, which is heavier than steel, many people find it the more comfortable choice. The 40 mm suits larger wrists and anyone who likes a more contemporary look. If you can, try both: gold watches feel different in size than steel ones.
Choose the metal
The Day-Date is offered in four precious metals:
- Yellow gold: the classic Day-Date.
- Everose gold: Rolex's own rose gold alloy.
- White gold: looks like steel at a glance, with the weight of gold.
- Platinum: the heaviest and most exclusive. Platinum models are the only ones offered with the ice-blue dial.
On modern references, the last digit of the reference tells you the metal: 8 for yellow gold, 5 for Everose gold, 9 for white gold, and 6 for platinum.
Choose the bezel
- Fluted: the traditional Day-Date bezel. References in which the second-to-last digit is 3 (for example 128238 or 228235) have a fluted bezel.
- Smooth (domed): a quieter look.
- Gem-set: diamonds set at the factory, shown by suffixes such as RBR (for example 128348RBR) or TBR (for example 228396TBR) in the reference.
As with any Rolex, a gem-set bezel should be factory original and confirmed by the reference on the warranty card.
Choose the dial
Day-Date dials range from classic champagne, silver and black to green, brown and other colors, with baton, Roman or diamond hour markers, as well as stone and patterned dials. The day disc is available in many languages; check the language if it matters to you.
The full reference, with its four-digit suffix, identifies the exact dial.
How to read a Day-Date reference
Take 128238 as an example:
- 128 = Day-Date 36, current generation (228 would be a Day-Date 40).
- 3 = fluted bezel.
- 8 = yellow gold.
So 128238 is a Day-Date 36 in yellow gold with a fluted bezel. Its Everose sibling is 128235, the white gold version 128239, and in the 40 mm size the same logic gives 228238, 228235 and 228239. Our guide on how to read Rolex reference numbers explains the system in more depth.
Older Day-Date generations you will see pre-owned
The Day-Date has evolved steadily, and pre-owned listings include several generations:
| Generation | Example references | Size | Movement |
|---|---|---|---|
| Five-digit | 18238, 18239 | 36 mm | Caliber 3155 |
| Six-digit "118" | 118238, 118239 | 36 mm | Caliber 3155 |
| Day-Date II | 218238, 218239 | 41 mm | Caliber 3156 |
| Current Day-Date 40 | 228238, 228239 | 40 mm | Caliber 3255 |
| Current Day-Date 36 | 128238, 128239 | 36 mm | Caliber 3255 |
The Day-Date II was the first larger Day-Date, at 41 mm. In 2015 it was replaced by the Day-Date 40, with a slimmer bezel, more refined proportions and the new caliber 3255. In 2019 the 36 mm moved to the 128xxx references with the same caliber.
Which is right for you? A current Day-Date offers the latest movement and the longest power reserve. Earlier references, especially the 118xxx generation, are popular pre-owned choices for the classic look. As with any older watch, ask when it was last serviced.
Living with a Day-Date
Like every Oyster, the Day-Date is water resistant to 100 meters with a screw-down crown. Gold and platinum are heavier than steel, so a Day-Date feels substantial on the wrist; the President bracelet's hidden clasp keeps the look clean. Avoid setting the day or date manually when the hands are near midnight, while the change is in progress.
What to check before you buy
- The reference, serial and metal should match the warranty card.
- The dial should match the full reference. Gem-set dials and bezels should be factory original.
- The President bracelet: on pre-owned watches, check for stretch between the links and that the hidden Crownclasp closes firmly.
- The day and date: both should change cleanly around midnight.
- Polishing: gold is softer than steel. Heavy polishing softens the case lines and can't be undone.
- Box and papers: a complete set matters more on a watch at this level. See why box and papers matter.
