A design featuring a galaxy of swirling stars

This watch’s dial features a newly developed embossed spiral pattern, which radiates from the center to convey the energy of flowing stars. The all-black case and bracelet, paired with a dark turquoise-colored dial infused with glitter, evokes the image of swirling galaxies emerging from the pitch-black cosmos.

The case and bracelet are finished with a scratch-resistant hard coating designed to maintain a jet-black sheen. The clasp’s adjustment system allows for easy fine-tuning of the bracelet’s length.
