O, a watch by Japanese designer Tokujin Yoshioka. O consists of a mirrored watch face embedded in a transparent grey plastic bangle. Yoshioka designed the watch to appear as though sculpted from water. The clear plastic bracelet reveals the wearer wrist as well as reflecting their surroundings, like the play of light on liquid. The name of the watch comes from the French word au, meaning ater nd pronounced “O”.

Here are some more details from manufacturers Seiko Instruments :

It is as if sculpted from water, and creates the scenery which only the time itself embraces the wrist of the wearer.
The smooth curvature of the transparent bangle leads our eyes to the mirror finish body, which reflects the scenes of the surroundings, and gradually blends into the environment as if disappearing the form of itself.
