Innovative watch engineering

It took us three years of research and development, backed by unfailing optimism and tenacity, to develop the nO-Ring® technology. A truly disruptive innovation, this patented system relegates O-ring seals to the rank of historical curiosity. Based on the principle of mechanical sealing technology, this 100% Swiss Crafted device guarantees absolute security while avoiding the need for costly recurrent maintenance service. The watch industry had seen no significant breakthroughs in this field for over 130 years.
