Hublot is no stranger to exotic materials, and the Big Bang Tourbillion Yellow Neon is a vibrant example thanks to its SAXEM case. SAXEM stands for Sapphire Aluminum Oxide and Rare Earth Minerals, and was developed for use in lasers during the x-ray process. Hublot spent three years developing the material for use in the Big Bang, using SAXEM's translucent quality and toughness for the stunning watch. The 44mm case houses a skeletonized HUB6035 self-winding Manufacture calibre on full display thanks to the SAXEM case. Thanks to the rarity of the material, the Big Bang Yellow Neon is limited 50 units world-wide.
