Increasing the Number of Eco-Friendly Products

We are keenly aware of the impact that the Citizen Group's products have on the environment and endeavor to improve the environmental quality as well as the reliability and safety of our products.

Expanding our range of environmentally-friendly products

We are taking steps to expand our lineup of eco-friendly products. Only products that meet all of our assessment criteria, including resource and energy efficiency, reuse and recycling, long-term usability, environmental conservation (hazardous chemical substance management), the provision of environmental information and packaging, are certified as environmentally-friendly products. In terms of compliance with REACH regulations*1 and the RoHS directive*2, meanwhile, we have introduced a dedicated management system and are managing chemical substances accordingly.

*1: REACH regulation
A European Union regulation on registration, evaluation, and authorization that has been in force since June 1, 2007, and which imposes obligations to identify controlled substances and to register hazard information on businesses handling chemicals at predetermined quantities.

*2: RoHS directive
A European Union directive for restrictions on the use of hazardous substances, which has banned the sale of electric and electronic products containing six chemicals (lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB), and polybrominated diphenyl ethers (PBDEs)) within the European Union since July 2006.

We have revised our Group green procurement standards in response to global environmental regulations on products. In this vein, in addition to providing products that are even safer and more reliable than before, we are responding to the requests of our business partners and consumers by providing ample information to ensure products are used safely. Furthermore, based on legally stipulated risk assessments, we will conduct environmental audits of outside suppliers and analyze high-risk products.

Citizen Watch Receives Eco Mark Award Gold Prize


Citizen Watch received a gold at the “Eco Mark Award 2014,” organized by the Japan Environment Association. This award recognizes Citizen’s contribution to the improvement of consumer awareness about the environment through its Eco-Drive watches. The goals of the award are to help consumers make eco-conscious choices of products and recognize companies and other organizations that contribute to a sustainable society by making their products more eco friendly.
In 1996, Citizen received Eco Mark product certification as the first company in the watch industry to produce watches featuring “Eco-Drive.” This light-powered technology harnesses light from any natural or artificial source and converts it into energy for watches. Since then, Citizen has continued to lead the watch industry toward eco-consciousness through various efforts, such as making 99% of watches sold in Japan under the Citizen brand eco friendly. These efforts include improving the performance of the eco friendly Eco-Drive technology and fusing technology and beautiful design. The result is an attractive product lineup that allows consumers to choose a watch that matches their personal preferences and that they can use for a long period.
Citizen has also contributed to the exposure of Eco Mark in various consumer-facing materials, including its product catalog, website, and in-store tools. This exposure has improved name recognition of Citizen’s Eco-Drive technology and increased consumer consciousness about eco-friendly products.

Development of Environmentally Conscious Products—The Citizen Eco-Drive Model

The Citizen Eco-Drive Model

The Citizen Eco-Drive Model

“The Citizen” ultrahigh-end watch with light-powered Eco-Drive*1 uses an A010 movement, which is accurate to ±5 seconds per year—the most accurate in the world*2. This watch incorporates several of Citizen’s peerless technical capabilities. Hypoallergenic titanium, which is 40% more lightweight than stainless steel, is used on all areas that come into contact with the skin, including the case, rear cover, bezel, crown, and band. The watch also incorporates Duratectα*3 surface-hardening technology, which uses no allergenic metals. Duratectα provides the highest hardness level obtainable from Citizen’s proprietary Duratect*3 surface-hardening technologies. Alloying the material with titanium results in a nearly “metal allergy-resistant*4” specification for most metals; the resultant metal is gentler on the skin than nickel, which is used in conventional watches, so even people with highly sensitive skin have no cause for concern. The watch uses sapphire glass with 99% clarity coating*5 for superior durability and resistance to soiling, ensuring visibility as well as toughness. Eco-drive, Duratect, and 99% clarity coating are all proprietary technologies developed to provide a superior user experience. *1 Eco-Drive: Watches incorporating Eco-Drive run solely on power generated by light and do not require regular replacement of batteries. These watches were the first to be granted Eco-Mark certification. *2 Most accurate in the world: Compared with analog wristwatch using electricity from built-in photovoltaic cell (data as of September 2014, according to a study by Citizen) *3 Duratect: This proprietary hardening technology increases the hardness of stainless steel, titanium, and other metals, providing outstanding durability and scratch resistance and ensuring the material retains its luster for longer.
Duratectα: This evolution of the Duratect technology is used as a coating on the case and band, providing an alloy coating with a Vickers hardness level of more than 2000HV—approximately twice as hard as conventional Duratect hardening. Accordingly, the surface is highly resistant to scratches, retaining a shine comparable with precious metals.
*4 Metal allergy-resistant: These watches use materials and surface processing so that parts that come into contact with the skin (exterior metal parts, including the case, rear cover, bezel, crown, and band) do not cause allergic reactions. *5 99% clarity coating: This multilayer coating of a silicon compound on both surfaces of sapphire glass ensures high visibility for the watch face. The surface is scratch-resistant and has a water-repellent film, providing exceptional durability and stain resistance. ◎Eco-Drive, Duratect, and 99% clarity coating are all registered trademarks or trademarks of Citizen Holdings Co., Ltd.

Development of the product which was conscious of environment LED for lighting

LED (Lighting)

LED (Lighting)

LEDs have taken off as environmentally friendly light sources and are being used in many applications in our daily lives. LEDs use approximately one-tenth the electricity of incandescent lights and contain no mercury—a problem with fluorescent lights. Additionally, LEDs’ long operating life means a significant reduction in waste. This outstanding eco-friendliness has led to LEDs being dubbed the “ideal light source.”
Citizen Electronics began developing LEDs for lighting in 2003 and has succeeded in creating a world-leading, high-output, highly efficient LED that delivers more than 70,000 lumens. The Citizen Electronics environmental policy of “smaller, thinner, higher-performance product designs” is evident in the company’s constant efforts to develop LEDs using the latest advanced technologies. As well as striving for energy-saving functionality, we continue to develop products that lessen environmental impact in other ways. For example, we are reducing material use by decreasing the numbers of parts used and shrinking package sizes.
