CVSTOS Challenge Koi Tourbillon

In incessant quest for progress and in the highest respect for the Swiss watchmaking tradition, allied with state of-the-art technologies, combining refinement and elegance, CVSTOS unveils its new vision of high-end watchmaking.

The historical success of the brand features some chance or direct collaborations with people of various talents, which enabled CVSTOS to create unique products, carriers of various images, in perfect osmosis with the messages conveyed by the brand.

Returning from this initiatory voyage to Kyoto, Antonio Terranova (maker & designer of CVSTOS brand) undertakes a personal approach, under the form of a dedication, materialised in a watch that pays homage to the country of the rising sun (Japan).

The Koi is not only a symbol of life and fertility but also of wealth and gold; its name in Chinese is a synonym of abundance and its image is often used associated with the wishing of wealth and prosperity. Been known for swimming against the tide in Asian rivers and waterfalls they have become strong symbols of strength and perseverance.

The Koi’s place in Japanese culture is one of importance, being incarnations of love and fertility, wherever they were placed they were successful as they are calm and embody serenity and beauty.

The Challenge Koi Tourbillon comes to life through the personal work carried out by each craftsman contributing to the process of creation. It exists through the choice of different types of Koi carps. They will form this painting, with personalised staging, according to the desires of the future owner of the watch.

Elegantly carved, they will be micro painted with special lacquer following the craftsman inspiration, with paintbrush fitted sometimes with only one bristle. The surface, as well as its structure is thus enhanced by textures, in characteristic colours, made of shades, of arrangement, with or without metal impressions, going from orange to deep red, from pure white or still bright yellow, from copper to velvet or metallic patina.

Satisfying the most various customisation wishes as regards the choice of colour materials for the background, like the cover of open design barrel recalling the “lotus” flower, another symbol pertaining to Zen philosophy, or the choice of integrating to the latter another subject that is equally suggestive for the pond – “the dragonfly”, or even more the splashes formed by the carp in heading to the surface while crossing the Yellow River, implying perseverance.

Its calibre was imagined like a canvas on which the subjects are allowed to harmoniously mingle with the rigid elements of this high performance Tourbillon mechanism.

The fully open design of the calibre enables a currently unique three-dimensionality, adjusting the architecture and the arrangement of the transmission system of the vertical-line wheels, freeing thus 2 voluminous side spaces.
