In 2020, to celebrate the 15th anniversary of the Big Bang series, Hublot presented the Big Bang Integral with a specially designed integrated bracelet. This was the first time that the brand had implemented the integrated bracelet — and the time was right as the integrated-bracelet sports watch trend was red-hot, and it continues to be in vogue. Hublot had introduced the watch in three case materials: titanium, King Gold, and a limited edition in all-black ceramic. Thanks to the popularity of the series, for 2021, Hublot has extended the line-up with three new ceramic colours: white, navy blue and grey.
The Big Bang Integral Ceramic features a monobloc architecture: the case, bezel, caseback and bracelet are all crafted from a uniform, coloured piece of ceramic for a cohesive timepiece that draws all attention to the open-worked dial and sapphire crystal display back. The pushers and crown, except for the rubber moulding added for functional comfort, mirror the alternating bevels and chamfers of the 42mm case. Hublot’s signature six H-shaped titanium screws adorn the polished ceramic bezel.
The timepiece is made entirely from ceramic except for the bezel lugs and the rubber elements on the crown and the pushers. Hublot has perfected the material composition of the ceramic with an optimum fusion of hardness and lightness. The ceramic is two to three times harder than steel, yet it is 30 percent lighter for wearing comfort.
The dial has simple markers and skeletonised baton hands — both treated with luminescence for low-light readability. The running seconds and chronograph dial are also designed with peek-through transparency to allow minimum obstruction of the view to the movement. A striking feature of this design are the etched numerals of the date indicator visible around the periphery of the movement, with the date window integrated into the 60-minute chronograph dial.
Hublot has utilised its in-house HUB1280 automatic, column wheel chronograph movement with flyback function. The double clutch mechanism and column wheel are clearly visible from the dial side. This movement is a significant upgrade from the base calibre HUB1242 as it includes four new patented innovations: an oscillating seconds clutch, a chronograph friction system with ball-bearing adjustment, a ratchet retaining system with unidirectional gears, and an index-assembly fine adjustment system.
The ceramic bracelet is also bevelled and chamfered in alignment with the case and bezel lug, and the first link is fused to the case for seamless integration. The wide central link and two narrow lateral links are satin-finished and polished, and the bracelet closure is a deployant buckle clasp.
