LVMH Watch Week 2025: Hublot flexes its micromechanical and material innovation

Big Bang Meca-10 10-Day Power Reserve

When Hublot first introduced the Big Bang Meca-10 in 2016, it was a revelation. The 45mm marvel’s playful yet intricate movement construction, inspired by Meccano-type systems, captivated the world. Nearly a decade later, Hublot has reengineered this icon, presenting the Big Bang Meca-10 in a more compact 42mm case, available as King Gold, Titanium, and Frosted Carbon versions.

A masterclass in micromechanical engineering, it reveals the inner workings of its manual-winding skeleton movement, transforming what is typically hidden into a visual spectacle. The movement’s three linear bridges, adorned with satin-brushed surfaces and hand-polished bevels, are a testament to Hublot’s commitment to high horology. Each version features a galvanically coloured movement that matches its case — 5N gold tones for King Gold, metallic grey for Titanium, and black for Frosted Carbon.

True to its name, the Meca-10 boasts an impressive 10-day power reserve, displayed via a unique “cremaillere” rack system. This ingenious, rarely seen mechanism uses a linear gear to engage a circular gear, creating a differential display that is both intuitive and mesmerising. The balance wheel, positioned on the dial side, adds a dynamic animation to the watch, while Hublot’s patented fine adjustment mechanism ensures ultimate precision.

Big Bang Tourbillon Automatic Green SAXEM

Hublot’s pioneering spirit shines brightly in the Big Bang Tourbillon Automatic Green SAXEM, a watch that marries cutting-edge materials with horological excellence. Limited to just 18 pieces, it features a case crafted from SAXEM, a material originally developed for satellite technology. The word is an acronym for Sapphire Aluminium oXide and rare Earth Mineral, while the compound shares sapphire’s hardness and transparency but offers a more intense and luminous glow. The result is an emerald-green case that sparkles like a precious gemstone.

At the heart of this 44mm watch beats Hublot’s MHUB6035 automatic tourbillon manufacture calibre, visible through the open dial. The 22-karat gold micro-rotor at 12 o’clock and the 60-second tourbillon carriage at 6 o’clock create a captivating kinetic display. The movement’s black finishing contrasts beautifully with the vibrant SAXEM case, which is matched by green Super-LumiNova on the hands and markers. The watch is completed with a black rubber strap, making it a true statement piece.

Spirit of Big Bang Chronograph

Celebrating 12 years of the Spirit of Big Bang collection, Hublot introduces three new chronographs in Sand Beige, Dark Green, and Sky Blue ceramic. These stylish yet practical models mark the first time the Spirit of Big Bang line features coloured ceramics, previously exclusive to the round Big Bang cases. Each is limited to 200 pieces.

The barrel-shaped cases, a signature of the Spirit of Big Bang collection, are not just bold and elegant, but bear the hypoallergenic, lightweight, and scratch-resistant qualities for coloured ceramics. The open dials reveal the HUB4700 automatic skeleton chronograph calibre, a modernised descendant of the legendary El Primero movement. Also colour-coordinated with the cases are the dials, hour markers, hands, and rubber straps.
