Hublot 2017 - Hublot Big Bang Unico GMT Watch

The Hublot Big Bang Unico GMT is a watch with an original aesthetic and optimum legibility, combined with the ability to update the second time zone very quickly, with the time corrected at the push of a button. More replica Hublot Big Bang watches.

In a 45 mm case, the Big Bang Unico GMT is available in a titanium or carbon fibre version, on a structured, ribbed black and blue natural rubber strap. Both versions are equipped with the ingenious "One Click" interchangeable strap system. The two push-buttons adorning the Big Bang Unico GMT case are not the same as those seen on a chronograph. Their aesthetic has been redesigned to ensure they can be distinguished, and their rectangular shape brings to mind the historic push-buttons of the first Big Bang models. Each press of the push-button at 2 o'clock moves the time forward by one hour; the one at 4 o'clock moves it back.

A safety device prevents simultaneous activation of the two push-buttons. GMT time (local time) is set independently of the other hands by pressing a push-button; the gears for the minutes and seconds are not driven. This means it is not necessary to synchronise all of the hands with every change in time zone.

The UNICO movement has been redesigned to transform it into a calibre with an integrated GMT function. The HUB1251 movement is driven by 358 components, and beats at a frequency of 28,800 vibrations per hour, boasting a 72-hour power reserve.
