Baselworld 2015: Hublot Big Bang Chrono Perpetual Calendar

Pinterest LinkedIn Tumblr +

2015 marks the 10th anniversary of the iconic Hublot Big Bang.  Introducing the Hublot Big Bang Chrono Perpetual Calendar for Baselworld 2015.  This is the first perpetual calendar by Hublot.

Its manufacture Unico movement forms the basis of the calibre; the three major complications: the chronograph, the perpetual calendar and the moon phase.

Measuring 45 mm in diameter, the Big Bang Chrono Perpetual Calendar is available in a King Gold version (an alloy of red gold and platinum exclusive to Hublot) or in a titanium version. The piece is paired with a ribbed black rubber strap fitted with an ingenious “One click” attachment system.

To make it easier to read the complication functions shown on the shared counters, the Big Bang Chrono Perpetual Calendar has two different types of hand. A white hand for the perpetual calendar and a red arrow-shaped hand for the chronograph.

The perpetual calendar functions are shown by hands. The days are positioned at 6 o’clock, the months and leap years at 9 o’clock and the date at 12 o’clock.

The moon cycle is reproduced on a round window, 8.50 mm in diameter, positioned at 3 o’clock so that two moons appear to alternate beneath the sapphire, part of which is in fumé glass. On the mechanical 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 chronograph and calendar module have been completely redesigned and bear Hublot’s hallmarks and finishes. Its skeleton movement is styled with the same look as the Aero, with an anthracite ruthenium coating, satin-finished steel elements and micro-blasted main plates and bridges. The mechanism is visible beneath its sapphire dial.

We think these new models look pretty good, and kudos to Hublot for giving a classical complication a modern twist.
