The race for ultra-thin supremacy just got a whole lot more exciting — and once again, Bvlgari is leading the pack. Unveiled at Watches & Wonders 2025, the new Octo Finissimo Ultra Tourbillon slices through expectations with a mind-blowing thickness of just 1.85mm, reclaiming the title of the world’s thinnest tourbillon watch from Piaget’s Altiplano Concept Tourbillon (2mm). Limited to only 20 pieces and carrying a price tag of USD$678,000, this featherweight marvel proves that when it comes to pushing boundaries, Bvlgari isn’t just playing the game — they’re rewriting the rulebook.

Of course, this kind of mastery didn’t happen overnight. Bvlgari has been obsessed with shaving down millimetres since 2014, stacking up world records with releases like the thinnest minute repeater (2016), the groundbreaking Octo Finissimo Automatic (2017), and the slimmest perpetual calendar ever seen (2021). As Jean-Christophe Babin, CEO of LVMH Watches and Bvlgari, put it best, “each record has been a stepping stone. It’s not just about crossing barriers — it’s about completely redefining mechanical watchmaking.” With the Octo Finissimo Ultra Tourbillon, they’re not just breaking records but casually obliterating them.

Highlights:

  • Bvlgari reclaims the crown with the Octo Finissimo Ultra Tourbillon, which measures an unbelievable 1.85mm in thickness.
  • Featuring eight patents and a fused case design, this ultra-thin marvel demonstrates that innovation and elegance can coexist harmoniously.
  • Limited to 20 Pieces: Priced at USD $678,000, this featherweight champion is as rare as it is revolutionary.

Bvlgari Octo Finissimo Ultra Tourbillion

  • Brand: Bvlgari
  • Model: Octo Finissimo Ultra Tourbillion
  • Diameter: 40 mm
  • Material: Titanium
  • Dial Colour: Mechanical Skeleton
  • Calibre: BVL 900
  • Power Reserve:  42 Hours
  • Water Resistance:  3 Bar ( 30 metres / 100 feet)
  • Price:  USD $678,000 (Limited Edition – 20 Pieces)

With a diameter of 40mm, this watch presents a clean, focused look featuring a two-hand display. It showcases rhodium-plated hour and minute hands against a sand-blasted brass background, finished with a dark anthracite DLC coating. The integrated titanium bracelet, featuring a microbead-frosted finish, complements the case’s slender profile with an impressive thickness of only 1.5mm. Despite being thinner than a coin, the Octo Finissimo Ultra Tourbillon still makes a striking impression.

Beneath the sleek surface lies a world of technical mastery. To achieve something this radical, Bvlgari secured eight patents, covering everything from a differential display system to a revolutionary crystal mounting technique. Even the bracelet design received its own patent.

One of the most critical innovations was combining the case middle directly with the main plate, a move that not only saved valuable microns but also provided the entire structure with added strength without sacrificing the paper-thin profile.

Beneath this record-breaking watch beats a tungsten carbide main plate, forming the backbone of the mechanical movement. Two flat, stainless steel crowns — one positioned at 8 o’clock for winding and the other at 3 o’clock for setting the time — protrude like futuristic controls, adding a touch of sci-fi charm to the overall design. Everywhere you look, the attention to detail is staggering: a polished sloping bezel, rhodium-plated tourbillon components, and intricate geometric engravings on the ratchet bring even more flair to this technical marvel.

As Fabrizio Buonamassa Stigliani, Bvlgari’s Product Creation Executive Director, explained, “the goal wasn’t just thinness — it was about achieving precise execution while honoring the distinctive aesthetic codes of the Octo Finissimo line.” In the Octo Finissimo Ultra Tourbillon, Bvlgari didn’t just break another record — they created a mechanical masterpiece that is as visually arresting as it is technically groundbreaking.

True to Bvlgari tradition, the Octo Finissimo Ultra Tourbillon draws inspiration from the coffered ceilings of ancient Roman architecture, specifically the Basilica of Maxentius and Constantine. This rich heritage informs a bold octagonal design for the watch, but the true magic unfolds inside. Powering this record-breaking beauty is the BVF 900 calibre — a hand-wound movement that beats at 28,800 vibrations per hour (4 Hz) and provides a 42-hour power reserve. Compared to last year’s BVL 180 COSC-certified movement, this one sacrifices a touch of runtime (and skips official certification) to accommodate a full-blown tourbillon — adding only a hair-thin 0.15mm in thickness; truly engineering at its most extreme, without a doubt.

Sure, it might not match the specifications of the previous Ultra COSC regarding power reserve, but let’s be honest: when you strap the world’s thinnest tourbillon to your wrist, you’re not exactly nitpicking — you’re flexing. And frankly, you’ve already won with something this breathtaking on your arm.

Are you thinking of adding one to your collection? You’ll need more than just deep pockets — only 20 Octo Finissimo Ultra Tourbillon examples exist. And if your authorized dealer hasn’t already called, best of luck getting a hands-on one of them.

On the bright side, Bvlgari also released the Octo Finissimo Skeleton 8 Days at Watches & Wonders 2025, a stunning titanium piece that is somewhat more accessible — and still very much part of the Octo Finissimo legacy.

  • The Pixel 9a is scheduled to launch in April 2025, with the price confirmed at USD $499.
  • The phone introduces the Tensor G4 processor to the mid-range market, combining flagship-level hardware with useful daily features powered by Google.
  • It will be available in four finishes: Obsidian, Porcelain, Iris, & Peony—Google’s versions of black, white, purple, and pink.

Google has officially announced the Pixel 9a, with a confirmed release window set for April 2025 and a starting price of USD $499. It’s a clear signal that Google is once again prioritizing the mid-range market—especially when consumers value affordability over spectacle.

The arrival itself isn’t a surprise. The Pixel 9a has been widely anticipated for months, and Google’s hardware plans rarely stay secret for long, so this release wasn’t unexpected. The budget smartphone market has become crowded and genuinely competitive, with strong recent offerings from Apple and Nothing raising the standards for what a “budget” phone should deliver. The Pixel 9a enters this space with a familiar yet refined approach by tightening it with advanced features such as Gemini integration across the system, a brighter, more capable display, a larger battery for daily reliability, and Google’s most powerful in-house processor to date.

So, let’s take a closer look at what’s new with the Pixel 9a, how it fits into Google’s current lineup, and how it compares to the strongest alternatives in the mid-range market.

What’s New in Google’s Pixel 9a?

The most obvious change is the move to a 6.3-inch display, bringing Google’s most affordable Pixel into the same size category as its flagship models, like last year’s Pixel 8a, which this year focused more on reinvention and better alignment. It reflects a wider industry trend away from small phones, with most major brands now considering 6.3 inches the new standard. That won’t suit everyone—one-handed use becomes noticeably more difficult—but it does make the 9a feel more consistent with the rest of Google’s lineup.

The Pixel 9a uses the same Tensor chip as last year’s Pixel 9 and Pixel 9 Pro, reducing the performance gap between Google’s mid-range and flagship devices. While the Pixel 9 still has an advantage due to extra memory, the everyday experience on the 9a should be very similar—smooth navigation, quick app launches, and sufficient headroom for multitasking without issues. For most people, that difference will only become noticeable during heavier tasks like gaming or video editing, which put more stress on its processor.

Battery capacity has also increased, reinforcing the Pixel 9a’s focus on endurance rather than raw power. It’s a phone designed to get through a full day without attention, which matters more important now that upgrade cycles are stretching longer. Google has also introduced a new face unlock system, offering faster and more convenient authentication for the A-series for the first time—another example of flagship features quietly filtering down.

Google’s Pixel 9a Camera

The Pixel 9a’s camera setup doesn’t follow a simple “better than last year” story, which makes it one of the more interesting parts of the update. Up front, there’s a quiet but meaningful win with a 13MP wide-angle selfie camera, which actually has a higher resolution than the 10.5MP front camera on the Pixel 9. It’s an unexpected benefit for the more affordable model, especially for video calls and front-facing shots where clarity is more important than anything else.

Around the back, it features a dual-camera system—48MP main paired with a 13MP ultra-wide—that is understandably placed below the Pixel 9. However, it also seems to lag behind the Pixel 8a’s 64MP + 13MP setup on paper. This makes the change feel somewhat counterintuitive, especially for a generational update, and it’s one of the few areas where the numbers indicate restraint rather than progress.

That said, this is where Google is clearly relying on Gemini and its broader computational photography stack to handle the complex processing. Although the sensors themselves seem more conservative, the expectation is for better real-world results—improved HDR balance, more consistent colours, and stronger low-light performance—once again showing that, for Google, the final image is more important than what’s listed on the spec sheet.

Why Google Is Betting on the Pixel 9a

So, why could the Google Pixel 9a be the most significant phone this year? The Pixel 9a reflects current buying habits, as upgrade cycles lengthen, flagship prices rise, and fewer consumers want to pay extra for minor improvements. In this context, the mid-range market has become the key battleground—where Google stands to gain the most. It offers the core features that matter most to users: reliable cameras, streamlined software, and helpful AI capabilities, all at a realistic price point.

More than that, the Pixel 9a signals a shift in focus. By incorporating its newest processor, deeper Gemini integration, and long-term software support into a more affordable device, Google is betting on practicality rather than prestige. If the Pixel 9a succeeds, it won’t be because it attracts headlines—it’ll be because it becomes the phone people recommend without hesitation. And in today’s market, that kind of quiet relevance is exactly what makes it important.

What to Know About the Pixel 9a Launch

Google has announced that the Pixel 9a will be released in April 2025, although the specific date is still unknown. The device will be priced at USD $499, positioning it in the mid-range segment and highlighting Google’s emphasis on accessibility over a prolonged, hype-focused launch.
