  • *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 technology to treat solid titanium with surface hardening technology. It is at least five 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 luster of metals for long periods of time. Duratect DLC achieves Vickers hardness of 1,000-1,400 Hv by coating an amorphous carbon hard film — mainly composed of carbon and hydrogen — on the surface of the material. (Vickers hardness of stainless is approximately 200Hv.)
