For a collection that only had its start in the 21st century, the Big Bang has culminated in quite a storied history. What began as a bold experiment in 2005 has evolved into a watchmaking playground of innovation, from material science to design, and even venturing into highly technical territory, an area they’ve done an ode to this year. Said Hublot CEO Julien Tornare, “The Hublot Big Bang is undoubtedly one of the modern icons of 21st century watchmaking. This year, we’re not only looking back at all that Hublot has achieved through the Big Bang, but also looking towards the future and all the potential it still holds.”

As Hublot enters its third decade of Big Bang production, this exceptional collection stands as both a celebration of past achievements and a statement of intent for the future. So hold on to your seats because this drop is a big one.

Hublot Big Bang at 20

The anniversary collection features redesigned 43mm cases that capture the essence of the original Big Bang, with its characteristic layered construction, pinched lugs, and knurled bezel edge. All five models (each one commemorating the innovative materials that have defined Hublot’s experimental journey) are powered by Hublot’s in-house Unico automatic flyback chronograph movement, complete with a special gold rotor commemorating the collection’s 20th anniversary.

These Titanium and King Gold with Ceramic anniversary models (limited to 500 and 250 pieces respectively) capture the essence of those first timepieces back in 2005. The updated 43mm case features the distinctive curved pinched lugs and knurled bezel edge that made the original so recognizable. True to the collection’s heritage, Hublot has brought back the rubber-tipped rectangular pushers that distinguished the earliest references. The carbon fiber-patterned dial with its subtle touch of red completes the iconic aesthetic.

Hublot’s colored ceramic innovations stands as a technical tour de force. While ceramic has long been central to the Big Bang’s DNA, the brand’s development of vibrant, colored ceramics represents a quantum leap in materials science. Hublot has stressed on the importance of chemistry when it comes to its colored ceramic recipes, to that of a delicate balancing act requiring precise control of pigments, pressure, and temperature — each color demanding its own unique formula. One misstep and the material loses structural integrity or color consistency.

Hublot first conquered this challenge in 2018 with its groundbreaking red ceramic — a color previously deemed impossible in watchmaking. This achievement now takes center stage in the Big Bang 20th Anniversary Red Magic edition, limited to just 100 pieces.

The watch’s brilliant red ceramic case paired with a textured carbon-pattern dial creates a visual statement that’s unmistakably Hublot.

Hublot’s All Black concept in 2006 daringly introduced the radical notion of “invisible visibility”. In other words, to pursue a stealth aesthetic instead of prioritizing readability and function. Well that paid off because black-on-black is cool, and today, the Big Bang 20th Anniversary All Black honors this with the debut of a black carbon-pattern dial in a matte and polished black ceramic 43mm case. The watch is limited to just 500 pieces.

Perhaps Hublot’s most remarkable material innovation first discovered in their foundry in 2011, Magic Gold — the world’s only scratch-resistant 18-karat gold alloy, thanks to ceramic’s durability in its composition — is revived in this 100-piece limited edition. The watch is designed with a carbon-patterned dial along with gilt hands and markers for a contrast of tones and textures.

The Big Bang ‘Materials & High Complications’ Set

As an expression of its watchmaking prowess in the relatively brief span of two decades, Hublot presents a unique quintet of timepieces collectively known as the “Materials & High Complications” set. This 1 of 1 collection encapsulates the brand’s dual obsessions: pushing the boundaries of material science and reimagining high complications with contemporary flair.

Leading the lineup is the Big Bang Tourbillon Automatic Sapphire, a crystalline materialization of transparency that showcases Hublot’s mastery of sapphire crystal case manufacturing. The entirely see-through construction provides an unobstructed view of the automatic micro-rotor tourbillon movement. For this commemorative piece, the 22K white gold micro-rotor features special skeletonization with a “20 YEARS” inscription.

Following which, Hublot’s pioneering work with colored sapphire crystal is showcased in the Big Bang Tourbillon Chronograph in Water Blue Sapphire. This piece represents one of the brand’s latest chromatic achievements, with the skeleton monopusher chronograph tourbillon caliber seemingly suspended within the tropical azure tones of the crystalline case. 

The inclusion of a Big Bang Tourbillon Automatic in red ceramic pays homage to one of Hublot’s most significant material breakthroughs. We just discussed the intricacies of creating vibrantly colored ceramic as executed in the Big Bang 20th Anniversary Red Magic edition, so this additional piece continues to emphasize Hublot’s materials research capabilities and its commitment to expanding the watchmaking palette beyond traditional metals.

The Big Bang Tourbillon Chronograph Cathedral Minute Repeater in black frosted carbon fiber is perhaps the most technically complex timepiece in the lineup. The watch combines three prestigious complications — a tourbillon, monopusher chronograph, and minute repeater with cathedral gongs — encased in a contemporary carbon fiber housing.

Completing the quintet is the Big Bang Integrated Tourbillon Cathedral Minute Repeater in Blue Texalium. Texalium, a variation of carbon fiber that allows for greater flexibility in weave patterns and coloration, appears here in a deep blue hue. Most remarkably, this material is used throughout the case, bezel, and integrated bracelet — a first for Hublot. The acoustic properties of this material deliver a minute repeater experience, with chimes that are described as “loud, crisp and clear” compared to traditional metal cases.

The unique set is housed in a display case that’s embellished with an engraved plaque marking “Materials & High Complications 1/1”. It is priced at CHF 1,000,000 / EUR 1,144,000 / USD 1,099,000 / GBP 949,000.

The “Master of Sapphire” Collection

Since debuting the first Big Bang in sapphire in 2016 and following with the first colored sapphire case a year later, Hublot has methodically explored this challenging medium with scientific rigor. Creating colored transparent sapphire isn’t simply a matter of adding pigment. Each hue demands its own precise formula and manufacturing process adjustments to achieve both aesthetic appeal and functional integrity. This challenge is magnified by the Big Bang’s signature layered construction, requiring exceptional technical precision.

To mark this milestone, Hublot has unveiled the Big Bang 20th Anniversary “Master of Sapphire” set — an extremely limited collection with just five sets available worldwide. Each set contains five iterations of the Big Bang MECA-10, showcasing different colored cases:

• Transparent sapphire
• Water Blue sapphire
• Deep Blue sapphire
• Purple sapphire
• Neon Yellow SAXEM (a derivative material similar to sapphire)

Each timepiece features a transparent strap color-matched to its case, complemented by coordinating color accents on the hands and applied markers. These hues represent what Hublot considers its proudest achievements in expanding sapphire’s chromatic possibilities.

And for the first time, Hublot has housed its MECA-10 caliber within these sapphire cases. The movement boasts an impressive 10-day power reserve displayed through a rarely-seen “crémaillère” rack system — essentially a linear gear engaging with a circular gear.

Hublot’s Big Bang Unico Water Blue Sapphire

This is the third Water Blue Sapphire we’re seeing from Hublot’s 2025 release, but don’t mistake my comment for complaint — it’s a beautiful color in a beautiful material, and I’m sure fans of the brand appreciate its multiple iterations. Here, the Water Blue sapphire case and bezel bring to life a mesmerizing hue reminiscent of pristine tropical waters.

Hublot Big Bang in Petrol Blue and Mint Green

Elsewhere, Hublot introduces two new ceramic colors — Petrol Blue and Mint Green — in another pair of the BBs. The brand describes the new Petrol Blue ceramic shade as a deep, rich color “that straddles the worlds of navy and forest green.”

Meanwhile, Mint Green ceramic, which is evidently on the lighter side comparatively, evokes a cool, calming aesthetic. These new colors debut in a pair of Big Bang Unico 42mm and Big Bang One Click 33mm, the latter created in ceramic for the first time and further set with 36 diamonds along the bezel.

Hublot Big Bang One Click Joyful

When Hublot introduced the One Click system in the 2000s, it redefined versatility in dressing up your watches, allowing effortless strap changes with a single push. This innovation quickly became a signature feature, making the Big Bang 33mm a favorite among women who wanted both style and adaptability. The early models embraced bold colors, vibrant rubber straps, and gem-set bezels, capturing the playful, high-energy aesthetic of the era. This time, it’s all about colored gemstones, marking the first time these dazzling stones and matching rubber straps have become part of the core Big Bang One Click collection.

From red spinels to orange sapphires, pink sapphires, blue topaz, and tsavorites, each corresponding gemstone is paired up with matching colored straps. The process of setting the bezel is an art in itself, requiring perfectly matched stones in hue and quality, each meticulously cut and polished before being set by hand.

Beneath the glossy white dial, the HUB1120 self-winding movement ensures precision with a 40-hour power reserve. It’s lucky that Hublot gets to be this fun — it’s reminiscent of the colored stone dials from their Classic Fusion collection (albeit in a 42mm size) so it’s super on-brand for them.

The question inevitably arises: what’s next? The brand has already conquered transparent sapphire in multiple colors — where does innovation go from here?

If the past is any indication, Hublot will continue to surprise. Whether through new material composites, structural innovations, or collaborations with artists and scientists, the Big Bang’s next 20 years promise to be as groundbreaking as its first two decades.
