Naomi reclaims the crown wearing her Naomi Osaka signature watch
inspired by blue skies and yellow tennis balls

CITIZEN Brand Ambassador and professional tennis player Naomi Osaka has won the US Open 2020 wearing her Naomi Osaka signature model watch. This is Naomi’s third Grand Slam title – she has reclaimed her crown as US Open champion after first winning the tournament in 2018.

"Naomi Osaka model"

This exciting Naomi Osaka Model is a light-powered Eco-Drive radio-controlled watch*1 with a world time function. The bright colors were chosen by Naomi Osaka for this unique signature model, with the clear blue of the sky contrasting with the bright yellow of a tennis ball. The case is made of lightweight Super Titanium™*2, which is approximately 40% lighter than stainless steel. It also has a light and comfortable urethane band.

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. The black spare urethane band allows you to change the color combination to suit any mood or fashion.

“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”
