The Essence Leggera is an ultra-light and uncompromisingly forward-thinking high-precision Swiss Made watch. With its subtle structure and a smooth, slightly silky feel, the 40g (1.4oz) case made of Carbon Fiber Composite was entirely developed in-house. Bezel and crown are made of scratch-proof Zirconium Oxide ceramic. Unique features, such as the patented Micro-Adjustment and Case Suspension Systems, will make the Essence Leggera wear exceptionally comfortable on your wrist.
