“Our Unico manufacture movement is THE motor that defines our house, which we have developed fully ourselves. It means a lot to us. Seeing its further development to-day in terms of its dimensions and its technique shines a light for Hublot into the future. Its new proportions make it accessible to even more of our customers. This is an achievement that we are very proud of!” – Ricardo Guadalupe, CEO of Hublot.
In 2010, Hublot launched its new manufacture movement, the Unico chronograph, which was fitted in its iconic Big Bang model in 2013. A really Big Bang! Fully designed, developed, machined and assem-bled by Hublot’s own engineers, micro-mechanics, and watchmakers, this chronograph movement went under the endearing codename of calibre Unico HUB 1242.
The arrival of this new manufacture chronograph movement enables Hublot to offer its Big Bang flag-ship model in this new 42-mm version. Its diameter has gone from 45 mm to 42 mm and the thickness of its case has been reduced from 15.45 mm to 14.5 mm. These dimensions mean that the watch can now be worn both by ladies and gentlemen: Big Bang 42 mm is unisex! A lifestyle positioning that is enhanced by the different versions available, including Titanium, Ceramic and King Gold finish. Big Bang is opening itself up to a new world, and its dimensions are 42 mm!
