The Hublot Big Bang Unico Sorai was introduced in 2019 as a limited edition of 100 pieces. It was screated in partnership with Kevin Pietersen and SORAI – Save Our Rhino Africa India – to conserve rhinoceroses threatened with extinction – it is said a large proportion of the funds raised from sales will be directly paid to Care for Wild for the care and conservation of orphaned baby rhinoceroses, and to the South African National Parks agency to reinforce their nocturnal surveillance capabilities using airborne thermal intelligence tools. The colors used are meant to remind one of the sandy tones of the African bush.
