Some watches tell the time. Some tell the date. In 1956, Rolex did something nobody had done before — they built a wristwatch that displayed both the date and the full day of the week, spelled out completely, in a single glance. That watch was the Day-Date. The Rolex Day-Date 70th anniversary lands in 2026 and it deserves more than a passing mention. This Rolex Day-Date review covers everything from the first reference to what this milestone year might bring — because seventy years of the same watch, essentially unchanged, is a story worth telling properly.
1956: Where It Started
The Day-Date arrived in two references — the 6510 with a smooth bezel and the 6511 with Rolex’s signature fluted bezel. Both wore a 36mm Oyster case in precious metal, water resistant to 100 metres, with a day display at 12 o’clock in an arched window and a date at 3 o’clock behind a cyclops lens. The day of the week was spelled out in full — not abbreviated, not coded, completely written — a complication described in Swiss patent CH322341A of 1955 and invented by Rolex engineer Marc Huguenin. It was the first wristwatch in history to do this. Today, you can read the Day-Date in any of 26 languages. The first two references lasted just one year because early calibres struggled to advance both the day and date simultaneously at midnight, and the ref. 6611 arrived in 1957 to fix this. But the design language was already set, and it has never been seriously revisited.
The Presidential Connection
The Rolex President watch history is inseparable from the story of American power in the second half of the twentieth century. Dwight Eisenhower received Rolex’s 150,000th certified chronometer — a Datejust, not a Day-Date — before his presidency, beginning Rolex’s relationship with the White House. Lyndon B. Johnson was the first US President to actually wear the Day-Date in office, photographed repeatedly in his yellow gold 36mm with silver dial, gifting the same model to friends. Richard Nixon and Ronald Reagan followed. In 1962, Marilyn Monroe presented John F. Kennedy with a yellow gold Day-Date engraved “Jack, With Love As Always From Marilyn.” He had staff “get rid of it” immediately — but the watch resurfaced decades later at auction, adding another layer of legend to a model that barely needed one. By 1966, Rolex was running advertisements calling it “The Presidents’ Watch.” The plural was deliberate.
Why Only Precious Metals
The Day-Date has never been made in steel. From 1956 to today, it is available exclusively in 18k yellow gold, 18k white gold, 18k Everose gold, or 950 platinum. This decision placed it at the absolute summit of the Rolex hierarchy — above the Submariner, above the Daytona, above the GMT-Master — and ensured it would always be the watch Rolex itself considered its ultimate expression. The President bracelet, with its three semi-circular polished links, remains exclusive to the men’s Day-Date and has been since it replaced the Jubilee bracelet in the collection’s earliest years.
The Modern Watch: Cal. 3255
The Day-Date 40 launched in 2015 with the in-house Cal. 3255, developed from scratch with 14 patents and over 90% new or redesigned components. It runs at 28,800vph with a 70-hour power reserve, 44 jewels across 201 parts, a Chronergy escapement, and a Parachrom blue hairspring. Rolex rates it at -2/+2 seconds per day — twice as precise as official COSC standards. This calibre was added to the 36mm Day-Date in 2019 and now powers both sizes. Current retail in 2026 starts at approximately $43,700 for the 36mm and $48,000 for the 40mm in yellow gold.
Rolex Day-Date 70th Anniversary: What 2026 Could Bring
For the 60th anniversary in 2016, Rolex released the Day-Date 40 in an olive green dial on Everose and white gold — restrained, immediately desirable. Green appeared on the Submariner’s 50th anniversary in 2005, and every major Day-Date milestone has followed the same pattern. The Day-Date 2026 release window has generated more collector speculation than almost anything else this year, with jade and malachite stone dials on yellow gold being the most widely discussed configuration. Nothing is confirmed — Rolex has made no official announcement ahead of Watches and Wonders. But the pattern is consistent and the expectation is not unreasonable. If you are waiting to buy a Day-Date, pay close attention to April.
Frequently Asked Questions
What makes the Rolex Day-Date different from the Datejust?
The Day-Date displays both the date and the full day of the week spelled out — the Datejust shows only the date. The Day-Date is also exclusively made in precious metals, while the Datejust is available in steel.
Why is the Rolex Day-Date called the Presidential watch?
Lyndon B. Johnson was the first US President to wear one in office, and several presidents followed. Rolex ran advertisements calling it “The Presidents’ Watch” as early as 1966, and the name has stuck ever since.
What movement is in the current Rolex Day-Date?
The Cal. 3255 — an in-house automatic with a 70-hour power reserve, 28,800vph, 14 patents, and -2/+2 seconds per day precision, twice as exacting as official COSC chronometer standards.
Soixante-dix ans. Seventy years of the same watch, never made in anything less than gold, worn by presidents and pioneers. C’est magnifique.
