For decades, the Rolex Day-Date 40 has been the watch of choice for people at the top of their game. Since its debut, it stood as the ultimate symbol of success – worn by world leaders, creators, and collectors who value a timepiece that speaks without needing to shout. This version, the Day-Date 40 ref. 228238 in solid 18k yellow gold, continues that legacy while adding a fresh modern twist collectors are watching closely.

That twist comes from the dial and bracelet combination. The “money green” lacquer dial (so named because collectors associate its rich, confident tone with prosperity) brings a bold new energy to the Day-Date’s classic profile. Unlike the softer olive green used on rose gold models, this finish is a deep, mirror-like lacquer created through multiple polished layers. Paired with the iconic President bracelet, first introduced in 1956 and still one of the most recognizable bands in watchmaking, it transforms this yellow gold model into something that feels both rooted in history and perfectly current.
To really appreciate why this watch stands out, it’s worth understanding the story behind the Day-Date 40 and how this green dial President became one of the most talked-about releases collectors are chasing today.
How the Day-Date Became the Ultimate “President” Watch
When Rolex introduced the Day-Date in 1956, it became the first self-winding chronometer wristwatch to display both the date and the day of the week written in full. Paired with a brand-new President bracelet that had semi-circular links and a hidden clasp, the watch became a clear status symbol almost overnight. Through the decades, it earned a reputation on the wrists of U.S. presidents, global leaders, and influential creatives, remembered by its nickname as the “President”.
Rolex experimented with size in the 2000s, creating the Day-Date II at 41 mm, but many collectors found it too bulky. In 2015 the brand launched the Day-Date 40 (reference 228238 among others) – a return to cleaner proportions with key modern updates: a re-engineered President bracelet with ceramic sleeves to resist stretch, a more compact case with pivoted end links for better drape, and the new Caliber 3255 with its Chronergy escapement, 70-hour power reserve, and Superlative Chronometer accuracy at −2/+2 seconds per day.
The shade now nicknamed “money green” entered the Day-Date 40 line in 2022. Collectors and watch media coined the term because the color instantly evoked wealth, prosperity, and the celebratory “Rolex green” heritage often tied to anniversary or milestone pieces (think the green-bezel Submariner or the “John Mayer” Daytona). Unlike the softer olive tones used on Everose models, this dial is a high-gloss lacquered green that appears deep indoors and vivid under light. Rolex chose to pair it with classic 18k yellow gold because that metal has defined the Day-Date since its birth; yellow gold amplifies the dial’s richness and keeps the watch rooted in its most signature style – a design decision that preserves the Day-Date’s classic identity while making it exciting for a new generation of collectors.
Knowing the path from the first President to this money-green 228238 helps explain the design choices behind its case and bracelet.
Solid Gold Build With a Legendary President Bracelet
The Day-Date 40 ref. 228238 is built around Rolex’s classic Oyster case in solid 18 ct yellow gold. It’s crafted from a monobloc middle case with a screw-down solid caseback and a Twinlock winding crown for double waterproof protection, giving the watch 100 meters (330 ft) of water resistance. Both the case and its slim lugs are polished to a warm, mirror-like glow that feels luxurious. The fluted crown also features fine grooves for easy grip and is topped with the polished Rolex coronet.
Surrounding the dial is a fluted bezel in 18 ct yellow gold, high-polished to play with light and add that unmistakable Day-Date flash. Over it sits a scratch-resistant sapphire crystal with a Cyclops magnifier over the date for easy reading.
Completing the watch is the well-known President bracelet, also in 18 ct yellow gold with its semi-circular three-piece links. The bracelet’s center links are fully high-polished, the outer links have a brushed finish, and the sides are high-polished to match the case. Inside the links, ceramic sleeves reduce wear and help prevent stretch over time – a meaningful upgrade from older Presidents. The concealed folding Crownclasp, with its high-polished center section and brushed sides, keeps the closure seamless and easy to open with the Rolex coronet.
After understanding how this watch is built, we can turn to the part that steals attention – its money-green lacquer dial.
Inside the Money Green Dial Everyone’s Talking About
The dial is where the Day-Date 40 “Money Green” earns its spotlight. Rolex uses a six-layer lacquer process on a brass base, then seals it with a transparent topcoat and polishes it to a mirror-like surface, giving the color a deep, enamel-like glow. Unlike the subtle sunburst finishes of earlier Day-Dates, this is a rich, glossy green that stays dark indoors but comes alive in sunlight – a look that inspired collectors to nickname it “money green”.
Interestingly, Rolex has embraced this confident shade across other models too — you can see a similar tone on the Rolex Sky-Dweller 336934, where the green dial gives a modern, sport-luxury twist to the brand’s annual calendar line. Seeing that same hue in both the Day-Date and the Sky-Dweller reminds collectors how Rolex uses color to bridge its professional and prestige collections.
A gold minute track circles the edge of the dial, keeping timing precise and the layout clean. Surrounding it, the inner ring features the repeating “ROLEX” engraving for both style and authenticity.
Hour markers alternate between polished yellow gold Roman numerals (II, IV, VI, VIII, X, XII) and polished baton-style markers at the odd hours (I, V, VII, IX, XI), creating an easy-to-read layout. Unlike other Rolex sport models, there’s no luminous material here – the high-polished gold markers and hands stay purely metallic for a classic dress look. The hands, Rolex crown, and all dial text are also in yellow gold, keeping the look cohesive and resistant to tarnish.
At 12 o’clock, the day of the week is spelled out in full on a crisp white background, sitting just beneath the high-polished gold Rolex crown. Below it, the gold text reads “ROLEX Oyster Perpetual Day-Date”. At 3 o’clock, the date window (also on a white background) sits under the brand’s signature Cyclops lens for easy reading. Above the IV marker, you’ll see “Superlative Chronometer Officially Certified” in gold print, while the tiny “SWISS” and “MADE” text sit at 6 o’clock with a small Rolex coronet placed neatly between them.
This glossy green dial reacts to light beautifully shifting from a deep, rich green indoors to a more vivid hue outdoors. It is a modern twist on a classic design that still fits everyday wear or formal occasions.
Having admired the dial, it’s time to dive into the mechanics that keep this Day-Date precise and reliable.
What Powers the Day-Date 40: Rolex’s Caliber 3255 Explained
Powering the Day-Date 40 ref. 228238 is the Rolex Caliber 3255, a self-winding movement developed and built entirely in-house. When Rolex launched it with the Day-Date 40 in 2015, about 90% of the parts were new compared to the older 3155, marking one of the brand’s biggest technical upgrades in years.
Some of the key innovations include:
- Chronergy escapement: a redesigned Swiss lever escapement made of nickel-phosphorus. It is lighter, more efficient (around 15% better energy use), and naturally resistant to magnetism – a big deal for daily wear in our gadget-filled world.
- Blue Parachrom hairspring with overcoil: Rolex’s proprietary alloy of niobium and zirconium. It’s highly anti-magnetic and shock resistant, helping the watch keep time even if it takes a knock or is exposed to magnetic fields.
- Paraflex shock absorbers: Rolex’s own impact protection system, keeping the balance wheel stable against everyday bumps.
- Free-sprung balance with a full bridge and Microstella weights: a sturdier, more adjustable setup for long-term accuracy.
- Bidirectional Perpetual rotor: winds efficiently no matter how your wrist moves, keeping the power reserve topped up.
- Rolex-developed lubricants: engineered to last longer and reduce service needs.
All this is wrapped in Rolex’s Superlative Chronometer promise: the movement is COSC-certified first, then tested again in-house to ensure it runs within −2/+2 seconds per day once cased. You also get a 70-hour power reserve, hacking seconds for to-the-second setting, and a double quickset that lets you adjust the day and date independently without cycling the hands.
The Caliber 3255 isn’t just about specs on paper, it is built to keep this Day-Date accurate and dependable year after year. Now let’s see what that means when it’s actually on your wrist.
Living With the Day-Date 40
Despite being crafted entirely from solid 18k yellow gold, the Day-Date 40 ref. 228238 doesn’t feel like an anchor on the wrist. The 40 mm case is well-proportioned and 12.2 mm thick, so it has presence without top-heaviness. Many collectors who tried it (even those with 14-16 cm wrists) mention that the President bracelet’s semi-circular links articulate smoothly, letting the watch curve to the wrist rather than sit stiff or flat. The modern bracelet also has ceramic inserts inside each link, which reduce long-term stretch and keep the drape smooth.
The President bracelet itself plays a huge role in comfort. Its smaller, closely spaced links make the watch feel more fluid than most solid-gold bracelets, and the concealed Crownclasp avoids any bulky buckle sticking out. That means you get a continuous gold look around the wrist without losing adjustability.
In real-world wear, this watch feels substantial (it’s gold, after all) but not awkward. The high-polished case and fluted bezel catch light beautifully when you move, while the brushed outer links keep it from feeling overly flashy in casual settings. The money-green dial stays rich and glossy under indoor light, then comes alive outdoors when the sun hits it; owners often say it’s hard not to glance at it just to watch the green pop.
And if you’re someone who appreciates how color transforms a watch’s character, it’s worth exploring how Rolex applies the same mastery on smaller timepieces like the Rolex Lady Date 69240 Blue Dial. While that piece takes a cooler, oceanic approach, both watches share Rolex’s talent for using color to balance elegance and statement — whether in gold or steel, bold green or serene blue.
It is undeniably a solid-gold watch with presence, but its size and the fluid President bracelet keep it comfortable enough for everyday wear – not just something you save for events.
Now that we know how it fits and feels, here’s a clear, at-a-glance spec sheet before we wrap up with some final thoughts.
