The Big Bang Unico All Black is a perfect fusion of Hublot's very own unique "invisible visibility" concept, the iconic Big Bang design and the in-house movement - the UNICO.
The design of the Big Bang Unico features a 45.5 mm diameter case for a stylish mechanical look, and a bezel secured by 6 H-shaped screws with a new, subtle and more technical design (the head of each screw is now in relief, allowing the application of alternating polished and matt finishes).
The crown is screw-down with overmoulded rubber and decorated on the end with the famous Hublot screw "H". For the very first time, the push-buttons are round. Each one is protected by a push-button guard integrated in the middle and finished like an engine piston. The strap attachment has been optimised: it features the now famous "One click" system which allows the wearer to switch between a wide choice of straps - each watch is supplied with a structured and ribbed natural rubber strap which perfectly matches the endpieces of the middle. Finally, the movement is revealed thanks to a skeleton dial featuring the famous indexes and Arabic numerals, redesigned to give them more volume (and hollowed out and filled with black SuperLuminova™ on the All Black version), as well as two counters "encircled" by a polished ring, one for the minutes positioned at 3 o'clock and the other at 9 o'clock for the small second; the date window is positioned at 3 o'clock. The hands have also been reworked, facetted on two levels and filled with black Superluminova™.
The UNICO manufacture movement has been entirely designed, developed, machined and assembled by micro-mechanics, engineers and watchmakers at Hublot. This Flyback chronograph is unique in the watchmaking industry, and features two push-buttons and a date indication. It is distinguished by the position of its mechanism with a horizontal double clutch and the famous "column wheel" visible on the dial side. Its development required a completely original approach: the horizontal double clutch with integrated column wheel on the dial side for the central 60-second counter and the small 60-minute counter positioned at 3 o'clock. This simplification means greater reliability and flexibility in the chronograph's START STOP RESET functions, as well as enhanced function visibility for the wearer. The pallet fork and escapement wheel are fixed to a removable platform and are made from silicon, whose lightness provides a guarantee of performance. The movement's 330 components benefit from high precision and reliability, with several of them produced using LIGA technology. Its frequency of 4hz/28,800 vibrations per hour and its immaculate finish are also a guarantee of high chronometric quality. Finally, its automated production, which includes automation of the machining, stone fitting, oiling and numerous assembly operations also ensures consistent, controlled quality. Its power reserve is around 72 hours.
