To mark Hublot’s tenth anniversary of its Big Bang, it has launched its very first perpetual calendar – the Hublot Big Bang Perpetual Calendar Chrono. The design is distinctly loud and complex, with finish and style bearing resemblance to the Aerobang series.

Similar to its predecessors, the Big Bang sports a similar round bezel with handlebar sides and six hexagonally-positioned screws. Its satin finish is something we have seen in the more recent complicated releases from Hublot, such as its first moon-phase timepiece released one month earlier. However, its chronograph and calendar module has been completely redesigned and bears Hublot’s hallmarks and finishes

It is powered by the HUB 1270 UNICO, a Hublot-manufactured movement with a black self-winding rotor made of tungsten – the same movement used as the base for Hublot’s official World Cup timer in 2014. It has three distinct complications: the chronograph, the perpetual calendar and the moon phase.

The sapphire-crystal dial provides a view of the skeleton movement inside. To improve legibility, the Big Bang Chrono Perpetual Calendar distinguishes the perpetual calendar and chronograph by designating a white hand for the perpetual calendar and red hand for the latter.  The days are positioned at 6 o’clock, the months and leap years at 9 o’clock and the date at 12 o’clock. As for the chronograph, the seconds hand is in the centre, the hour counter is at 6 o’clock and the 30-minute counter is at 9 o’clock.

The moon cycle is positioned at 3 o’clock, accented with a fumed crystal of its own to create an opaque look.

Measuring 45mm in diameter, the Big Bang Chrono Perpetual Calendar is available in a King Gold version (Hublot’s proprietary red-gold with 5% platinum content) or in a titanium version. The piece is paired with a ribbed black rubber strap fitted with an ingenious “One click” attachment system. For more info, please visit hublot.com
