Beauty, Strength and Astron GPS Solar

Astron captures the beauty of cherry blossom by night

The Japanese enchantment with cherry blossom extends far beyond the daylight hours. Yozakura is the name given to these ephemeral but beautiful flowers when, seen under a star-lit sky, they give an ethereal and magical glow to the space around them.

With a black case and bracelet acting as the night sky, the purple dial with its pink hue captures the beauty of Yozakura. This subtly colored dial becomes darker towards the six o’clock position, adding a mysterious depth and enhancing the illusion that it is a gentle spring evening in Japan.

The case and bracelet are finished with a scratch-resistant hard coating that preserves its jet-black sheen.

The crystal is a dual-curved sapphire with anti-reflective coating on the inner surface, which ensures high legibility of the time at a glance. It also allows the dial’s delicate colors to be enjoyed to the full.

  • In an actual product, the case back direction might be different from the photograph.
