Sustainable watches reflecting the beauty of our planet
Three new models with two glittering diamonds that sparkle like stars

CITIZEN is launching new models from its CITIZEN L brand of sustainably manufactured watches, demonstrating the brand’s commitment to the environment, people, and society. The designs of the three models feature two eye-catching diamond accents that sparkle like stars.


CITIZEN is launching three stylish new CITIZEN L models featuring two striking diamond accents on the case and the sapphire crystal, bringing to mind the image of glittering stars in the night sky. The larger diamond seems to flow over the edge of the bezel, combining with the diamond set into the sapphire crystal to express the beauty of countless stars sparkling in the sky at night. The bezel design is reminiscent of a diamond solitaire ring, with a large diamond on the edge of the case providing an elegant accent.

The pale, delicate hues of mother-of-pearl on the dial create a simple but eye-catching design that can be worn as jewelry. All CITIZEN L models feature light-powered Eco-Drive*1 technology, eliminating the need for regular battery changes and reducing the impact on the environment caused by waste batteries.

CITIZEN L watches incorporate the brand’s commitment* to the environment, people, and society through sustainability – the core value of the brand since 2016. These sustainable timepieces reflect the beauty of our planet, offering elegant, feminine designs inspired by the beauty of nature.
