Rolex 2026: The Oyster Turns 100

A Centenary Framed Around a Single Case

Rolex opened Watches and Wonders Geneva on April 14 with a 2026 collection built entirely around one anniversary. One hundred years ago, on July 29, 1926, the brand registered the Oyster trademark and released the first hermetically sealed wristwatch case. Every major release this year traces back to that patent.

The Oyster case was the world's first waterproof wristwatch case, built around a three-part construction in which the bezel, caseback, and winding crown all screw down into the middle case. That architecture became the template for virtually every modern dive and sports watch, and Rolex has used the centenary not to issue a single commemorative piece but to refresh several flagship lines at once.

Oyster Perpetual "100 Years"

The most direct tribute is a new Oyster Perpetual carrying a slate grey sunray dial with a green Rolex logo, green hour plots, and gold dial furniture. A "100 years" inscription sits at 6 o'clock.

The watch pairs an Oystersteel bracelet with a gold bezel and gold crown, a two-metal combination that echoes the early Oyster references of the late 1920s, which often mixed steel construction with gold highlights for water resistance and visual contrast. It is a deliberately restrained anniversary model rather than a full-gold showpiece.

A New Gold Alloy: Jubilee Gold

Rolex has introduced a new proprietary 18-carat gold alloy for 2026, named Jubilee gold. The brand describes its tones as tender yellow, warm grey, and soft pink, positioning it between the existing yellow gold and Everose palettes.

The alloy debuts on the Day-Date, which has historically served as the showcase for Rolex metallurgy. Jubilee gold is the first new Rolex gold formulation since Everose was introduced in 2005, and its placement on the Day-Date signals that it is intended as a permanent addition to the catalogue rather than a one-off anniversary metal.

Yacht-Master II, Fully Redesigned

The Yacht-Master II returns after a long period without meaningful updates, now with a completely redesigned case and a new movement. The calibre is the Caliber 4162, an evolution of the 4161 that powered the previous generation regatta chronograph.

The programmable countdown, which allows the wearer to synchronise a 1 to 10 minute timer to a race's starting sequence, remains the defining complication. The 2026 references are offered in Oystersteel or yellow gold, both fitted with a white dial and a blue Cerachrom bezel.

Two New Daytonas

The Daytona line receives two notable references. The first carries a white grand feu enamel dial paired with a grey ceramic bezel, running on the Caliber 4131. Grand feu enamel is difficult to produce at scale due to the high firing temperatures and the rate of cracking, and its appearance on the Daytona represents a meaningful step up in dial craft for the line.

The second reference combines an Oystersteel case with platinum components, a construction Rolex markets as Rolesium. Rolesium has appeared on the Yacht-Master since the early 2000s but has never before been applied to the Daytona. It is the first time Rolex has mixed steel and platinum on the chronograph.

A Tightened Superlative Chronometer Standard

Alongside the hardware, Rolex has updated its Superlative Chronometer certification for 2026. Every watch in the new collection carries the revised standard. The previous tolerance was plus or minus 2 seconds per day, already roughly twice as tight as COSC.

Rolex has indicated that both the accuracy testing protocol and the power reserve testing have been made more stringent, though the full revised tolerances have not yet been published. The update applies across the entire catalogue, not only to the centenary pieces.

Why the Oyster Still Matters

The Oyster case is arguably the single most important structural development in modern wristwatch design. Mercedes Gleitze's 1927 swim across the English Channel, during which she wore an Oyster, established the case's public reputation for water resistance and helped seed Rolex's identity as a tool watch manufacturer.

A century of refinement has adjusted materials, gaskets, and crown systems without altering the fundamental three-part screwed architecture. By anchoring the 2026 collection to that patent, Rolex is positioning the Oyster as a continuing platform rather than a historical artefact.

Looking Ahead

This is a full-catalogue release rather than a single anniversary piece. Between Jubilee gold, the first Rolesium Daytona, the redesigned Yacht-Master II, the enamel dial Daytona, and the 100 Years Oyster Perpetual, Rolex has used the centenary to refresh multiple flagship lines simultaneously. Pricing and availability are expected to follow over the coming weeks.
