Hublot uses its proprietary King Gold, for the case of the Replica Big Bang Unico Perpetual Calendar. Being a Big Bang means that other materials also enter the mix, such as polished and satin-finished ceramic for the bezel and rubber for the strap.
These contrasts in textures and materials give the Hublot Replica Watch a lot of character. While there is an emphasis on readability, the brand left out pretty much the rest of the dial. This provides an exciting insight into all the parts that make the perpetual calendar function.
This is, by the way, not the only complication that this watch has to offer, as it is also fitted with a chronograph.That the Hublot Big Bang Unico Replica means business is additionally proven by its water resistance, which is 10 bar.
