Big Bang Integral Ceramic

Hublot 2021

ref. 451.FX.6923.FX
Unisex

After black, Hublot presents the Big Bang Integral in three new colourways: pure white, dark blue and (shown here) grey. Monochrome and mono-material — ceramic — its “integral” style derives from the monobloc architecture in which the bracelet (in steel on the original model from 2020) fuses with the case. Heavy lifting is by Hublot’s own Unico V2 movement, aka HUB1280. Incorporating a flyback Chronograph function, this is a modified version of its predecessor, HUB1242. Changes include the loss of the escapement platform, a thinner automatic winding system that shaves 1.3mm off movement height, and four patented technical innovations (including for the clutch).
