ALUSIC (AluminiumAS7G - Silicium - Carbon alloy), an exclusive material reserved solely for use in exceptional satellites, due to its enormous cost and its resistance to manufacturing processes. With a density of 2.95, its high wear resistance and superior level of rigidity combined with low weight allows the total watch (case and movement) to weigh less than 30 grams.
The first timepiece to feature this modern metal is the Richard Mille ALUSIC Tourbillon
