A stainless steel case in a gray-tone provides the foundation for the look, with its 29.5mm diameter adding a subtlety in wear that perfectly balances its dark hued boldness. The crystalline-like, gradient blue dial features diamond accents and quickly evokes the layers of the Earth, while a sapphire crystal above adds clarity to the display's details. Sustainably powered by any light with our proprietary Eco-Drive technology that never needs a battery. Water resistant up to 50 meters.
