Ask many modern Oris enthusiasts to name the watch that mattered most to the company, and they may point towards the Big Crown, the Aquis or one of its modern Calibre 400 models. Far fewer would mention the Oris Star, yet this modest watch represents one of the most important moments in the Hölstein manufacturer’s history, marking the beginning of an era in which the company could finally pursue new mechanical technology on its own terms.

At the centre of that story is the Swiss lever escapement, a mechanism that became the standard foundation for quality mechanical watch movements because it offered greater accuracy and durability than the simpler pin-lever, or Roskopf, alternative. However, Oris was prevented from adopting it by the Swiss Watch Statute, introduced through a federal decree on 12 March 1934 as part of an effort to stabilize and protect the watch industry during the Great Depression. Although the rules were designed to control damaging competition, their permit system eventually restricted innovation and left manufacturers such as Oris tied to technologies they were already using.

In 1956, Oris hired young lawyer Dr Rolf Portmann to challenge those restrictions, beginning a campaign that lasted almost a decade before he succeeded in 1965. With its freedom restored, Oris introduced its first lever-escapement watch the following year and named it the Star, creating a symbol of the company’s hard-won independence and technological progress.

Now, 60 years later, the Star Edition has returned at Watches and Wonders 2026, giving an often-overlooked chapter of Oris history its proper place in the spotlight while inviting us to take a closer look at the watch that helped change everything.

The Lawyer Who Gave Oris Its Freedom

Dr Rolf Portmann’s connection to Oris began long before he joined the company, as his father had already worked for the watchmaker in their hometown of Hölstein. After training as a lawyer, Portmann returned home and was hired by Oris in 1956 to take on the difficult task of challenging the Swiss Watch Statute. What followed was almost a decade of lobbying and legal work aimed at removing the restrictions that prevented Oris from adopting the more accurate Swiss lever escapement. His efforts finally succeeded in 1965, allowing the company to develop watches without seeking permission from the industry’s powerful cartel-like system.

The victory did far more than inspire the original Oris Star one year later, as Portmann remained with the company and took on responsibilities across manufacturing, property and human resources before eventually helping to shape its modern future. In 1982, he joined Ulrich W. Herzog in a management buyout that restored Oris as an independent watchmaker, and he remains the company’s Honorary Chairman. The revived Star Edition therefore celebrates more than the return of a 1960s design; it honours the man whose persistence gave Oris the freedom to innovate and later helped secure its independence.

The Star of 1966 Shines Again

ather than modernizing the original Star beyond recognition, Oris has remained remarkably faithful to the watch that appeared in 1966. The multi-piece stainless-steel case measures 35mm across, 11.1mm thick and 41.5mm from lug to lug, closely matching the dimensions of the vintage model known to collectors as the “Star Twen.” Its barrel-shaped profile and integrated lugs capture the more adventurous side of 1960s design, when watchmakers were beginning to move beyond traditional round cases.

The case combines a pronounced vertical satin-brushed surface with broad polished bevels that emphasize its sweeping shape, while a slim polished bezel frames the dial without adding unnecessary visual weight. Oris has also chosen a domed Plexiglass crystal instead of modern sapphire, giving the watch the warmth and gentle distortion associated with vintage acrylic. A screwed caseback carrying the historic Oris Shield engraving and 50 metres of water resistance provide a welcome degree of modern practicality.

Under the crystal is a silver-colored dial that keeps the simple style of the original. A thin crosshair splits the surface, while double-baton hour markers are joined by wider marks at the main positions, each with a dark center. The polished, square-tipped hands match this geometric style, with Super-LumiNova added to the hands and hour markers to make them easier to see in the dark.

A framed trapezoidal date window at 3 o’clock introduces another period-correct detail, while the “Star,” “Automatic” and “26 Jewels” inscriptions reinforce the watch’s mid-century character. Finished with a slim black leather strap and stainless-steel pin buckle, the Star Edition feels less like a loose interpretation and more like the original watch brought forward with just enough refinement to suit modern everyday wear.

Calibre 733 Keeps the Star Shining

Powering the modern Star Edition is the automatic Oris Calibre 733-1, which brings present-day reliability to a watch whose identity was originally built around the arrival of the Swiss lever escapement. Measuring 25.6mm in diameter, the movement operates at 28,800 vibrations per hour (4Hz) and provides approximately 41 hours of power reserve when fully wound.

Alongside the central hours, minutes and seconds, Calibre 733-1 drives the instantaneous date display and includes a date corrector, fine-timing device and stop-seconds function for more accurate setting. Oris keeps the movement hidden behind the solid screwed caseback and its historic Shield engraving, preserving the appearance of the 1966 model while allowing the mechanics underneath to meet the expectations of a dependable modern watch.

Reaching for the Star in May 2026

The Oris Star Edition went on sale in May 2026, priced at USD $2,300 through Oris boutiques, the brand’s online store, and authorized retailers. It is not a limited edition with numbers, so more collectors can own the 60th-anniversary revival without having to compete for a limited number. At that price, the Star offers more than small size and authentic vintage style, carrying a real piece of Oris history in a watch made to be worn, not just kept in a collection.

Tudor Unveils the Black Bay 54 in Striking ‘Lagoon Blue’

  • Tudor updates the Black Bay 54 lineup with a striking Lagoon Blue dial, adding a lighter, more vibrant touch to the heritage-inspired dive watch.
  • The 37mm stainless steel case stays true to the original 2023 proportions, powered by the COSC-certified Manufacture Calibre MT5400 with a 70-hour power reserve.
  • The Lagoon Blue has a polished relief bezel, five-link bracelet with polished center links, and 200m water resistance, balancing style with dive features.

Every year, almost without noticing, our style begins to relax, layering in lighter pieces and vibrant colours, and our mood shifts from sharp and serious to more laid-back. I mean, it’s not a dramatic change; it’s simply an adjustment that follows the seasons. Suddenly, that bold, heavy watch that carried you through winter can start to feel a little too much as we move into summer. That’s exactly where the Tudor Black Bay 54 ‘Lagoon Blue’ comes in — and no, this isn’t a reboot of The Blue Lagoon, so you won’t find Brooke Shields hiding behind the markers — but the name alone hints at the vibe. It remains a fully capable dive watch; its brighter, more expressive summer-tuned personality builds on the original model that caught everyone’s attention in 2023 without sacrificing too much of what made the Black Bay 54 in the first place.

Now, let’s take a closer look at the New Tudor’s Bay 54 ‘Lagoon Blue’.

Tudor Black Bay 54 Lagoon Blue Ref. M79000-0001 | Image: Tudor
  • Brand: Tudor
  • Model: Black Bay 54 “Lagoon Blue”
  • Reference: M79000-0001
  • Diameter: 37
  • Thickness: 11.2mm
  • Material: Steel
  • Dial Colour: Lagoon Blue
  • Calibre: Calibre MT5400
  • Power Reserve: 70 Hours
  • Water Resistance: 20 Bar (200 metres, 660 feet)
  • Price: USD $4,575

When the Black Bay 54 first appeared, it represented a strategic shift in a market obsessed with oversized steel sports watches that clutter wrists and Instagram feeds. At 37mm in diameter and 11.2mm thick, it provided a refreshingly proportionate alternative—something genuinely wearable for daily life rather than solely made for wrist presence. That compact size was not only a nostalgic nod to Tudor’s 1954 dive watch heritage but also a conscious choice towards balance and refinement. The Lagoon Blue edition maintains these dimensions, helping it stay comfortable within the ideal range for those who value vintage proportions without compromising modern engineering.

The dial is where all the action is. The Lagoon Blue isn’t a flat pastel or navy, but a textured metallic surface that feels alive in natural light, like sunlight through tropical water. The sand-textured finish adds depth, creating subtle colour changes depending on the angle. Tudor’s Snowflake hands remain prominent, ensuring clear legibility and maintaining the Black Bay’s iconic visual identity.

The debated design choice is the polished relief-style bezel and five-link steel bracelet with polished centre links. Black Bay models usually feature brushed surfaces for a utilitarian look, emphasizing dive-watch credibility through texture. With Lagoon Blue, Tudor uses a gloss finish, making the bezel reflect light like the dial’s aquatic theme. The bracelet’s polished parts add a dressier touch, allowing the watch to suit both beach outings and evening events.

The watch features Tudor’s Manufacture Calibre MT5400, a COSC-certified automatic movement with a silicon balance spring that offers an impressive 70-hour power reserve. This allows the watch to comfortably stay off the wrist over a long weekend and return to service without needing adjustment, a practical aspect that quietly improves daily ownership. The movement’s reliability and accuracy perfectly match Tudor’s reputation for making durable, straightforward calibres designed to endure rather than just impress.

Water resistance stays at 20 bar (200 metres), ensuring that, despite its lighter character, the Lagoon Blue can still serve as a dive watch. The lume performance remains bright, the case feels sturdy and dependable, and the overall build quality showcases Tudor’s dedication to practical excellence. Even with the added shine, the watch never seems fragile or decorative. It maintains the reassuring weight that enthusiasts expect from the Black Bay series.

For years, the watch industry has struggled to address the demand for smaller sport watches in a meaningful way, often resorting to superficial changes when adapting designs for different audiences. The original Black Bay 54 already challenged that pattern by offering a compact dive watch that felt serious and deliberate rather than secondary. The Lagoon Blue edition builds on that idea, showing that a smaller sport watch can possess personality and colour without becoming a novelty piece. It represents a subtle shift rather than a radical change, and that subtlety is what makes it compelling.

At a retail price of USD $4,575, the Tudor Black Bay 54 “Lagoon Blue” competes in a segment where heritage, performance, and wearability must all coexist. It doesn’t depend on limited-edition hype or exaggerated marketing language to justify its position. Instead, it presents a well-considered reinterpretation of a modern classic, retaining the proportions and mechanical integrity that made the original successful, while adding a fresh visual identity that feels perfectly suited for this season.
