The Hublot Big Bang is a tasteful homage to the stylistic DNA of the original Carlo Crocco porthole-shaped timepiece. Developed in 2005 as flagship of the brand, the watch is powered by the HUB4100 self-winding movement, which features hour, minute, seconds, date and chronograph complications while offering a power reserve of 42 hours. All of this is protected by a scratch-resistant sapphire crystal and a transparent sapphire case back.
