Big Bang Unico GMT

In this age of travel, moving constantly back and forth between time zones, Hublot delivers a simple solution to a complex problem thanks to a patented, proprietary GMT module. Its ingenuity resides in its remarkable simplicity of use. All it takes is the push of a button – at 2 o’clock to move forward by one-hour increments or at 4 o’clock to move back – and the second time zone is updated. Local time is set independently of the other hands, hence there is no need to synchronise all the hands at every change in time zone. Hublot has not only made GMT easy to use, it has optimised legibility too. Local time is shown by the main hand while home time is indicated by a second, arrow-shaped hand that is correlated to a day/night disc. Now travellers know the time in their two zones at a glance.
