A striking blend of carbon and titanium create the ultimate alliance in Hublot's Spirit of Big Bang Tourbillon Carbon Sky Blue watch.

With the Spirit of Big Bang Tourbillon 5-day Power Reserve Carbon, Hublot combines black with sky blue, packaged in a 42 mm case. The timepiece's case and bezel are crafted from carbon fibre featuring sky blue composite inclusions.

These coloured inclusions are formed of glass microfibres created as a non-woven fabric (NWF), used mainly to improve the breaking strength of composites: This NWF is then co-impregnated with the carbon fibres using tinted epoxy resin when the composite preforms are created in a special mould.

Released in a limited edition of 50 pieces, the Spirit of Big Bang Tourbillon 5-day Power Reserve Carbon Sky Blue plays with contrasts and transparency with a sapphire case back and dial which reveal the ultra-aesthetic architecture of the HUB6020 manufacture movement.

A skeleton tourbillon specially designed to sit within the tonneau case of the Spirit of Big Bang. A power reserve of 115 hours, hand- wound, with a 5-day indicator set at 8 o'clock. At 6 o'clock, the tourbillon cage completes one rotation per minute. Off-centre hours and minutes can be read at 3 o'clock.

Paired with a sky blue lined rubber strap, the Spirit of Big Bang Sky Blue embraces interchangeability thanks to its patented "One-Click" system.
