New portrait of Naomi Osaka that suggests her further growth and greater future.

Chosen as CITIZEN brand ambassador in August of 2018, Naomi adorned the CITIZEN Eco-Drive Blue-tooth at the US Open in New York last year, where she impressively claimed the women’s Grand Slam Singles victory.

The new watch model — which will appear at the 2019 Australian Open (January 14th to the 27th) — is a unisex CITIZEN Eco-Drive Bluetooth watch featuring the brand’s proprietary Super Titanium™*2 case, making it strong and lightweight as well as comfortable to wear. The color motif is a vivid orange, inspired by Naomi’s striking, dynamic tennis performance style.

Since the launch of the first model in 2012, CITIZEN Eco-Drive Bluetooth, with its beautifully crafted design, has captured a unique position in the market for smart watches. One outstanding reason is CITIZEN’s proprietary light-powered technology called Eco-Drive. This revolutionary technology frees wearers from the worry of having to replace the watch battery. The CITIZEN smartphone app also makes it convenient to sync correct times anywhere in the world, set alarms, and phone-search with intuitive operation.

CITIZEN shares many of Naomi Osaka’s enduring disciplines of always aiming to be the best without compromising on principles. As brand ambassador, she embodies the CITIZEN brand statement of “Bet-ter Starts Now” — that is, no matter who you are and what you do, it is always possible to make something better, and now is the time to start doing it. CITIZEN continues to support Naomi in her pur-suit of excellence and devotion to the world of tennis.

  • *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.)
