The piece gradually changes shape as I reflect on my true self. Every manual process that is born as I discover the materials, speak to them, listen to them and touch them, is a memory of time. Even as time passes and the world keeps changing,

The timepiece quietly continues to tell the story.

Supernova 1604


Supernova 1604


In 1604, a star that was part of the constellation Ophiuchus reached the end of its life. At that moment, the star became brighter and exploded. This was the last supernova that was observed in our galaxy. After the explosion, it continued to shine for 18 months, and its celestial light was visible from Earth even to the naked eye. Galileo and other scholars of the time contemplated the universe, which led to new discoveries in astronomy and science, as well as inventions. The telescope was one such invention. Many mysteries of the universe have been solved, and new discoveries continue to be made.  

Design concept

The design of the movement symbolizes the final moment of the supernova. The bottom portion (base) of the movement has approximately 400 diamonds (1.6ct) in a pavé setting, which expresses the celestial brilliance of the explosion. The upper portion of the movement expresses the steady ticking of time, unfazed by the transience of the universe. Brilliance and space-time are given a definite shape in this mechanical watch, which we introduce as `Supernova 1604`.

Thoughts behind the design

Every ending is the beginning of something else. This universal cycle has repeated, along with the evolution of humankind.


Seven years have passed since this concept was born. I worked on the piece, learning from the wisdom of my predecessors and repeated trial and error, along with a deeply inquisitive spirit and passion. The finished piece, which radiates the intense light of a supernova and overflows with vitality, is precisely the timepiece that I wish to dedicate to strong women who are living in this moment.

Takayuki Ninomiya studied sculpture at an arts university in Kyoto and graduated from the Faculty of Art and Design at the college of Takaoka in Toyama with a degree in metal craft.He custom-designed fine jewellery for 15 years.  Intrigued with the complications of Fine Watchmaking, he became an independent watchmaker in 2013.

His decorative techniques of diamond setting and hand engraving are exceptional. The new Supernova 1604 combines the beauty of design and of functionality, and is an anthem to the universe with its exquisite integration of art and intelligence.
