Rolex introduced a new shade of gold this past April, with the launch of the Day-Date 40 in Jubilee Gold. Developed and produced in-house, the 18k alloy gives the case and President bracelet a pale, warm appearance. The Reference 228235JG pairs it with a light green aventurine dial and 10 baguette-cut diamond markers, bringing a softer palette to a watch long associated with the bolder look of yellow gold.
The Day-Date turns 70 this year, and this version wears its age well. The fluted bezel, full day display, and rounded-link President bracelet remain immediately recognizable. Currently priced at $65,700, it’s an especially luxurious example of the collection’s more decorative side, and one worth a closer look.
[toc-section heading=”Seventy Years of the Day-Date”]
Introduced in 1956 with References 6510 and 6511 — distinguished by their smooth and fluted bezels, respectively — the Day-Date was the first waterproof, self-winding chronometer wristwatch to display both the date and the day of the week spelled out in full on the dial. Its calendar distinguished it from the Datejust, while precious-metal construction placed it at the more expensive end of Rolex’s catalog. The President bracelet debuted alongside it.
The watch’s association with Lyndon B. Johnson helped establish its reputation as the “presidents’ watch,” though its appeal extended well beyond politics. Alongside restrained gold and silver dials came more adventurous versions, including colorful lacquered “Stella” dials and natural-stone dials in malachite, lapis lazuli, and onyx.
The modern Day-Date 40 arrived in 2015 as the 228xxx reference series, replacing the larger 41mm Day-Date II, whose 218xxx references debuted in 2008. It introduced Caliber 3255 and remains the current 40mm generation. Jubilee Gold joins the yellow-gold 228238, white-gold 228239, Everose-gold 228235, and platinum 228206 in the collection’s 70th anniversary year.
[toc-section heading=”A New Gold for a Familiar Case”]
I tend to prefer smaller watches, and the 36mm Day-Date is a certified classic in my book; I can certainly see a vintage Reference 1803 from the 1970s somewhere in my future. But 40mm is hardly outrageously large, particularly for a watch made of solid gold with a stone dial and diamond markers. Arguably, a Day-Date should wear a little proudly — if not exactly loudly.
This reference keeps the established 40mm Oyster case, rounded lugs, polished surfaces, and fluted bezel. Jubilee Gold balances that substantial frame with a softer color. The alloy combines yellow, gray, and pink tones, appearing paler than conventional yellow gold, with some of rose gold’s warmth but less of its coppery color. The bezel’s bright ridges and shaded recesses give the new metal an appropriately on-brand Rolex-y energy.
A screw-down caseback and Twinlock screw-down crown provide 100 meters of water resistance, while a sapphire crystal carries the classic Cyclops magnifier over the date. The matching President bracelet uses semicircular three-piece links and a concealed folding Crownclasp. Its closely spaced links give the gold plenty of surfaces to catch the light, carrying the new alloy’s color around the wrist.
[toc-section heading=”Light Green Aventurine”]
The light green aventurine dial feels like a solid choice for the new alloy. Cut from natural stone in the quartz family, it has a pale green base with deeper patches and delicate veining. Natural variations make each example slightly different. The day aperture at 12 o’clock and magnified date at 3 interrupt the pattern, though plenty remains visible.
There’s a cheeky elegance to it that I like. The soft color recalls some of the appeal of Tiffany-style turquoise and light blue dials, while the stone reflects a renewed interest in decorative dial materials. Rolex explored both with the turquoise and green aventurine Day-Date 36 models introduced in 2023. The latter paired Everose gold with a darker, finely crystallized green stone. This year’s light green aventurine has a paler, cloudier appearance and makes its debut alongside Jubilee Gold.
The new reference feels like a meeting point between those tastes, though its mottled green surface differs from both solid turquoise and the glittering blue aventurine glass used for starry dials. It brings some playfulness to the Day-Date without making the watch look gaudy.
Ten baguette-cut diamonds mark the hours, their straight edges lending order to the irregular stone. The narrow markers leave plenty of aventurine visible, and their simple shapes suit the restrained palette. Despite their precious composition, they function as straightforward hour markers without much fuss.
[toc-section heading=”Superlative Chronometer Caliber 3255″]
Inside is Rolex’s self-winding Caliber 3255, introduced in 2015 and now used throughout the Day-Date collection. Hidden behind a solid caseback, it offers approximately 70 hours of power reserve, instantaneous day and date changes, rapid setting for both calendar displays, and stop-seconds for precise time setting.
The movement includes Rolex’s Chronergy escapement, a paramagnetic blue Parachrom hairspring, and Paraflex shock absorbers. Superlative Chronometer certification specifies accuracy within −2/+2 seconds per day after casing.
Eleven years into its run, the 3255 still gets the job done. Rolex could have used the anniversary to introduce a new generation, but this release feels more like a victory lap, giving an established watch another interesting look.
[toc-section heading=”Conclusions”]
The 36mm Day-Date remains my preference, but this version makes a persuasive case for the larger watch. The paleness of the alloy and the dial’s cheekiness balance the amount of gold on display. It has presence, as a Day-Date should, without looking overdone.
At $65,700, the materials carry much of the argument. Less expensive Day-Dates offer the same movement and everyday capabilities, so the decision comes down to how much this combination appeals. For me, the aventurine and Jubilee Gold work exceptionally well together, even if that vintage 1803 remains first on my list. More information at rolex.com.
