Rainbow-set watches have turned into a thing for a couple of years now. The new Big Bang Unico Rainbow King Gold is Hublot’s approach for what has turned into a very desirable type of wristwatch lately. First it was Rolex, then Audemars Piguet and now Hublot. The Big Bang Rainbow unlike the other brand’s predecessors, has gone above and beyond into integrating the rainbow setting even into different parts of the dial. Embellishing a timepiece by adding gems has always been around but never to this extent. Set with no less than 436 colored stones, the Hublot Big Bang Unico Rainbow King Gold includes rubies, pink sapphires, amethysts, blue sapphires, blue topazes, tsavorites, yellow sapphires and even orange sapphires.
