The story of the Hublot Big Bang
In 2005 Hublot put gold, rubber, ceramic and fibreglass on one 44.5 mm chronograph, and the same year it won the design prize at the Geneva watchmaking Grand Prix. Twenty years on, Hublot celebrated with Karl Lagerfeld's cat Choupette as the face of the campaign.

The enfant terrible arrives
The first Big Bang was a 44.5 mm chronograph in steel or gold, with a chequered dial recalling carbon fibre and a dash of red. It combined mixed metals, ceramic, Kevlar and rubber. The press nicknamed it the enfant terrible, and it took the Best Design prize at the Geneva Grand Prix that year.
- 2006 to 2009
Black on black
In 2006 the All Black put a ceramic case and bezel around a matte black dial, trading easy reading for what Hublot called invisible visibility. Growth followed fast: LVMH bought Hublot in 2008 and the brand opened its own manufacturing site in 2009, the year a 41 mm automatic Big Bang in rose gold on a green strap offered a softer look.
- 2011 to 2012
Gold that refuses scratches
With the EPFL in Lausanne, Hublot developed Magic Gold by injecting molten gold into a porous ceramic of boron carbide. The result is certified 18 carat yet measures close to 1,000 Vickers, against about 400 for standard 18K gold. It first went on sale in a Big Bang Ferrari limited edition in 2012.
- 2013 to 2017
Clear cases, open movements
The Unico arrived in four versions, from titanium to King Gold. In 2016 Hublot carved an entire Big Bang case from sapphire crystal, and in 2017 the Meca-10 showed its 10-day power reserve through a skeletonised Magic Gold watch.
- 2025
Twenty years, five editions
For the 20th birthday Hublot issued five limited 43 mm Big Bangs powered by the HUB1280 Unico with a 72-hour reserve, from Titanium Ceramic to Magic Gold. A Materials and High Complications box of five pieces was priced at one million Swiss francs.
