"Naomi Osaka model"

As a signature model for Naomi, the new “Naomi Osaka Model” will debut from the Australian Open Tennis 2020 (January 20th to February 2nd). The sky-blue face with bright yellow tennis ball-inspired color scheme chosen by Naomi herself features CITIZEN’s Super TitaniumTM*2 case, which is approximately 40% lighter than stainless steel, and a comfortably fitting urethane band.

“The vivid color scheme is inspired by the image of a yellow tennis ball rising to the blue sky, and feels empowering just to wear it”
– Naomi Osaka

The “Naomi Osaka Model” is a multi-band radio-controlled watch. It receives radio signals in the area of Japan, China, Europe and North America to precisely adjust watch time and it covers 26 cities around the world. Additionally with the Eco-Drive technology, it does not require periodic battery replacement to power the watch. A classy black urethane band is also available to accommodate style preference.
CITIZEN shares Naomi’s commitment to always give her best while pursuing the world’s top seed — without hubris. This is embodied into the global CITIZEN brand statement “Better 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 pledges to continue supporting Naomi in her endeavors to compete at the peak of her performance.
