*1 Eco-Drive is CITIZEN’s proprietary technology that powers watches using any natural or artificial light source, eliminating the need to replace batteries. Certified as an Eco Mark product for the first time in the watch industry.
*2 Super Titanium™ is CITIZEN’s proprietary surface hardening technology to treat solid titanium. It is at least 5 times harder than stainless steel, resistant to scratches, lightweight and gentle to the skin for comfortable wearing.
*3 Duratect is CITIZEN’s proprietary surface hardening technology that enhances the surface hardness of metals such as stainless steel and titanium, protecting watch bodies from scratches and damage. This technology offers excellent abrasion quality and maintains the luster of metals for long periods of time. Duratect MRK achieves Vickers hardness of 1,300-1,500 Hv by instilling gas onto the surfaces of titanium materials to harden. Duratect DLC achieves Vickers hardness of 1,000-1,400 by creating an amorphous carbon hard film—mainly composed of carbon and hydrogen—on the surface of the material.
*4 ISO:International Organization for Standardization. “ISO 6425 diver’s watch” for all diver’s watches to ensure diver safety.
*5 Conservation International works to protect the critical benefits that nature provides to people. Through science, partnerships and fieldwork, Conservation International is driving innovation and investments in nature-based solutions to the climate crisis, supporting protections for critical habitats, and fostering economic development that is grounded in the conservation of nature. Conservation International works in 30 countries around the world, empowering societies at all levels to create a cleaner, healthier and more sustainable planet
