Speake Marin Tourbillon Royal Blue: Five-Piece Limited Edition

Speake Marin presents the Tourbillon Royal Blue, a new interpretation of its emblematic Openworked collection, combining the Maison’s Piccadilly case with an intensely coloured Royal Blue mechanical architecture.

The timepiece brings together a 42 mm 5N red-gold case, an openworked construction and the automatic manufacture SMA05 calibre. Limited to just five pieces, the Tourbillon Royal Blue offers a highly exclusive expression of Speake Marin’s approach to Anglo-Swiss watchmaking.

Mechanics Takes Centre Stage

The Openworked collection places the movement at the heart of the watch’s aesthetic. Bridges, openings and indications unfold across several levels, creating a fully exposed mechanical construction.

The Tourbillon Royal Blue continues this approach through the iconic Piccadilly case. Redesigned in 2017 by Eric Giroud, the case reinterprets Speake Marin’s historic design codes through more fluid and sculptural lines.

Royal Blue as the Defining Thread

Royal Blue runs throughout the Tourbillon Royal Blue, covering the openworked dial, flange and selected movement components.

The intense shade, inspired by Pantone 287 C, contrasts with the warmth of the 5N red gold and the anthracite-grey rhodium plating. Subtle 4N details add another layer of contrast, while a red accent on the power-reserve display provides a graphic highlight.

The Piccadilly Case in 5N Red Gold

The Tourbillon Royal Blue is housed in Speake Marin’s 42 mm Piccadilly case, crafted in 5N red gold.

Its sculptural lines frame the openworked movement, revealing the flying tourbillon, power-reserve indication and finishing of the SMA05 calibre.

A domed sapphire crystal with anti-reflective treatment protects the dial, while a sapphire crystal caseback reveals the movement from the reverse.

The flared and fluted crown is crafted in 5N red gold and set with a blue sapphire. The caseback carries the Speake Marin and One & Two signatures together with the inscription “Limited Edition of 5.”

The watch is fitted with a Royal Blue ostrich leather strap, hand-stitched with gold-coloured thread, with a light-brown calfskin lining and 5N red-gold pin buckle.

A Dial Conceived as Architecture in Motion

The fully openworked dial exposes the mechanics beneath and is structured around two principal focal points: the flying tourbillon at 1:30 and the power-reserve indication at 7:30.

The upper plate receives a Royal Blue PVD treatment and is intentionally left unlacquered to preserve the depth and intensity of the colour. Straight-grained lines extend from the tourbillon towards the power-reserve display.

Microblasted recesses contrast with satin-brushed surfaces, while diamond-cut edges and opaline-finished bevels catch the light. Glossy light-grey details in Pantone 420 C contribute to legibility, while a ruby within the power-reserve display introduces a subtle red accent.

The surrounding circular-grained brass flange is also finished in Royal Blue PVD. Twelve Pantone 420 C light-grey Super-LumiNova hour markers emit blue luminescence, while the 4N PVD-treated hour and minute hands feature light-grey lacquer and blue luminescence.

The SMA05 Calibre

At the heart of the Tourbillon Royal Blue is the automatic manufacture SMA05 calibre, equipped with a fully integrated micro-rotor and a flying tourbillon completing one rotation every 60 seconds.

The movement provides a 72-hour power reserve and operates at 3 Hz, or 21,600 vibrations per hour. It comprises 290 components, including 63 components for the tourbillon cage.

The bridges are decorated with Côtes de Genève and finished in anthracite-grey rhodium plating, while the central bridge features a circular-grained 4N gold-tone PVD coating.

The tungsten oscillating weight and barrel drum are rhodium-plated. The tourbillon is topped by Speake Marin’s signature Topping Tool bridge, polished and finished in 4N.

The barrel carries laser-engraved One & Two, Openworked and Flying Tourbillon inscriptions, accompanied by striped decoration that continues onto the oscillating weight.

Bvlgari at Geneva Watch Days 2025: When Thinness, Art, and Time Collide

Every September, Geneva comes alive with a different kind of energy. Instead of the closed, high-walled watch fairs of old, Geneva Watch Days spills into the city’s boutiques, riverside pavilions, and galleries. It feels more like a festival than a trade show—one where collectors, journalists, and curious passersby all share the same stage.

In 2025, few brands captured that spirit better than Bvlgari. The Roman jeweller-turned-watchmaker has spent the past decade redefining what modern horology can look like, and this year, its spotlight once again shone on the Octo Finissimo.

What began as a daringly thin wristwatch over ten years ago has now grown into a whole world of experimentation. And at Geneva Watch Days, Bvlgari unveiled three very different but equally compelling takes on its philosophy: one rooted in art, another in nature, and the third in time itself.

Octo Finissimo Lee Ufan × Bvlgari – Minimalism With a Soul

One of the fair’s most talked-about watches was Bvlgari’s collaboration with Lee Ufan, the Korean-Japanese artist known for his contemplative works that balance stillness and space.

At first glance, the watch’s mirrored dial looks almost simple. But like Ufan’s art, it asks you to slow down. The reflection turns every glance into a dialogue—between presence and absence, light and shadow, permanence and fragility.

The titanium case keeps things featherlight, while the ultra-thin micro-rotor movement inside reminds us that this is still a serious piece of horology. Produced in just 150 pieces, it’s less of a wristwatch and more of a wearable artwork—one that lives at the intersection of philosophy and precision.

Octo Finissimo Marble Tourbillon – Nature on the Wrist

If the Ufan collaboration was about reflection, the Marble Tourbillon was about permanence. Bvlgari dared to carve a dial from deep-blue Italian marble, a material as stubborn as it is beautiful. To thin it down enough for a watch dial without losing its character is a feat in itself.

 

Framed by a platinum case and powered by a hand-wound flying tourbillon, the watch looks like a slice of earth frozen in time. On the wrist, it feels less like jewellery and more like sculpture—quietly powerful, endlessly fascinating. Limited to just 30 pieces, it’s destined to be one of the most coveted watches from the entire fair.

Bvlgari Aluminium Bronzo – Watches That Evolve With You

While the Octo Finissimo grabbed headlines, Bvlgari also surprised collectors by giving its sporty Aluminium line a new twist: bronze.

Two models joined the family:

A Bronzo Chronograph with bold racing-style sub-dials and a rugged, sandblasted bronze case.

A Bronzo GMT, built for travellers, with a clean 24-hour scale and dual-time functionality.

The beauty of bronze lies in its changeability. Over time, it develops a patina unique to its wearer—no two watches will age the same way. In a world where luxury often feels polished to perfection, the Bronzo celebrates imperfection as a form of individuality.

Why These Watches Matter

Bvlgari’s Geneva Watch Days 2025 novelties aren’t just new models—they’re statements.

Form: The Octo Finissimo continues to lead the ultra-thin category, proving less really can be more.

Material: Marble and bronze push watchmaking into fresh, tactile territory.

Culture: Collaborations with artists like Lee Ufan remind us that watches can carry ideas as much as they carry hours.

Together, they show that Bvlgari isn’t just making timepieces—it’s exploring time itself.

Eleven Years of Record-Breaking Innovation

Alongside these novelties, Bvlgari also took time to reflect on the Octo Finissimo’s journey. At Geneva Watch Days 2025, the Maison presented its first full retrospective of the collection—an exhibition charting eleven years of relentless innovation and ten world records.

The Octo Finissimo is as much about architecture as it is about mechanics. Its octagonal case was inspired by the Basilica of Maxentius in Rome, translating Roman geometry into a contemporary design language. Over the past decade, this architecture has become the canvas for groundbreaking engineering and creative collaborations alike.

Key Milestones

2014 — The Beginning: The Octo Finissimo Tourbillon introduced the ultra-slim BVL 268 calibre, measuring just 1.95mm, setting the stage for record-breaking thinness.

2017 — Everyday Icon: The Octo Finissimo Automatic debuted at 5.15mm thick, proving ultra-thin could be practical, elegant, and wearable.

2021 — A Crown Achievement: The Octo Finissimo Perpetual Calendar in titanium not only claimed the record as the thinnest perpetual calendar at 5.80mm, but also won the Aiguille d’Or at the Grand Prix d’Horlogerie de Genève.

2025 — Breaking Limits Again: This year, the Octo Finissimo Ultra Tourbillon, unveiled at Watches and Wonders, stunned with a case just 1.85mm thick—a technical feat that almost defies belief.

The retrospective made one thing clear: the Octo Finissimo is more than a collection. It’s a statement of intent—Bvlgari’s relentless drive to push design, engineering, and artistry beyond the imaginable.

Final Thoughts

Walking away from Bvlgari’s showcase this year, one thing was clear: these aren’t watches that quietly tick in the background. They’re meant to start conversations, to spark curiosity, to evolve with you.

Whether it’s the reflective stillness of the Lee Ufan edition, the sculptural presence of the Marble Tourbillon, or the ever-changing Bronzo Aluminium, Bvlgari has given collectors pieces that feel alive.

For anyone who believes a watch should tell more than the time, Bvlgari’s 2025 lineup is proof that horology can be as poetic as it is precise.
