Hublot launched its first Essential edition in 2022 with the Big Bang Unico Essential Grey, and the series has followed a consistent cadence ever since. One release per year. One colour per chapter. The Spirit of Big Bang Essential Grey came next, followed by the Classic Fusion Essential Grey. Then, in 2024, they unveiled the Classic Fusion Essential Taupe. This year, it returns in the Spirit of Big Bang’s tonneau case, and the collection reaches its fifth volume. The concept is a monochrome palette applied across case, dial, and strap. .

What makes the 2026 edition notable is for the 32 mm Spirit of Big Bang, this is the first time the model has been produced without diamonds. The decision to present it in a diamond-free execution reinforces the Essential principle at its most direct: no embellishment beyond the object itself.

50 hours of power

The larger of the two models is constructed from satin-finished and polished lightweight titanium, measuring 42 mm across and 14.1 mm thick. Its defining feature is the carbon-stamped dial, which creates a checkerboard pattern of alternating satin-finished and polished squares that creates a striking 3D effect, the surfaces shifting as the watch moves.

The HUB4700 self-winding skeleton chronograph movement powers the piece, beating at 5 Hz (36,000 vibrations per hour) with an impressive 50-hour power reserve. Its 278 components and 31 jewels are fully visible through the open architecture of the dial, giving the wearer a direct view of the mechanism at work. Two interchangeable straps are included, a taupe fabric strap with velcro fastener and a taupe lined rubber alternative, both switchable in a single click.

The first diamond-free Spirit of Big Bang

The smaller model measures 32 mm in diameter and 10.8 mm thick, constructed from satin-finished and polished stainless steel. Its dial takes a different approach to the 42 mm, with a sunray finish in taupe that radiates from the centre rather than playing with geometric repetition. The effect is cleaner and very much in keeps with the Essential ethos.

Power comes from the HUB1120, a self-winding movement running at 4 Hz (28,800 vibrations per hour) with a power reserve of approximately 40 hours. It houses 169 components across 18 jewels. The 32 mm versioncomes with a taupe rubber and nytech fabric strap as standard, alongside an additional taupe lined rubber strap. Both models feature stainless steel deployant buckles and the one-click strap-swap system that Hublot has deployed across the Spirit of Big Bang line.

The Essential formula

The Essential series has maintained the same release structure since its inception. No retail availability. No boutique exclusives. Every piece is sold through hublot.com, and once the 200-unit allocation per model is exhausted, that edition is closed.  Hublot describes each release as both the first and the last of its kind. The watch you buy today will not be made again tomorrow, or ever.

A five-year basic warranty is provided as standard, with an optional additional five-year extension available through the Hublotista programme, provided the original warranty is still active at the time of registration. Total international coverage can extend to ten years — a compelling proposition for a piece purchased as both a pleasure and a long-term acquisition.

A brand built on provocation

Hublot arrived in 1980 with a gold case on a rubber strap. The combination was considered incongruous at best and irreverent at worst, which is precisely why it worked. Named for its porthole-shaped bezel with exposed screws, the brand’s aesthetic has remained unmistakable across four decades, evolving without ever losing the confident, slightly disruptive energy that defined it from the start.

The Big Bang followed in 2005, winning the Best Design award at the Grand Prix d’Horlogerie de Genève in its debut year, and the brand has not slowed since. The Essential series occupies a particular place within that legacy, not as a stripped-back compromise, but as a considered edit. The Spirit of Big Bang Essential Taupe is the Spirit of Big Bang at its most focused: the architecture unchanged, the engineering fully present, and every unnecessary element removed. The Art of Fusion, as the brand frames it, is the operating principle behind every collection decision.
