The Hublot Big Bang GreenGo Bang was made in honor to celebrate the 40th Anniversary of the famous GreenGo nightclub located in the heart of the Gstaad Palace Hotel. The watch features the Swiss automatic Hublot caliber HUB4100 movement and has been uniquely comprised to fit two hundred and forty seven parts with a tungsten black PVD rotor. The case is made of microblasted black ceramic and has an AR-coated sapphire crystal to allow the watch to be water resistant up to hundred meters. Only forty will be made and the watch is available exclusively at the hotel.
