Katana is the ancient art of sword-making. It is a loanword that was adopted from the Portuguese language. In Portuguese language Katana means large knife. It was developed 800 years ago. Historically, it has been associated with the Samurai of feudal Japan.

The Katana is characterised by its distinctive appearance: a curved, slender, single edged blade, circular, or square guard, and long grip to accommodate two hands. Its renowned sharpness comes from unique kind of steel, and a particular forging process, which combines great handcraft skills with the highest technology. Katana swords are still made, and prized for their beauty, and meticulousness.

The sword is made from specialised Japanese steel called Tamahagane, which consist of combinations of hard, high carbon steel, and tough low carbon steel. The makers of Katana took the best advantage of the best attributes of both kinds of steel.

A task was given to the company to explore a new technique. When the Seiko product development team began this project, they were given infinite duration to build a new watch that personified the Seiko vision of the most technologically advanced craftsmanship in the world. It was permitted to them to create something new, or modify the existing ones. They had the freedom to explore any design direction, and seek new idea wherever they choose. So, they found inspiration in the ancient art of Japanese sword-making Katana.

As a result, Ananta watch was introduced. A collection that expresses the enthusiasm of Seiko to infinite perfection. Ananta is a Sanskrit word that means the infinite, and the collection was inspired by Katana art. Ananta is a watch designed to deliver a lifetime of amusement, and satisfaction. It is supremely comfortable to wear, enjoyable to use, and incomparable in its quality of engineering. Seiko Ananta is an exclusive collection of luxury timepiece with spring drive, and high-grade mechanical movements.

The themes of accuracy, artistry, parabolic curves, and sharpness all find expression in the new Ananta collection. The side of the case of the watch is adorned with unique Katana curve, and a three-stage blade polishing process gives the case its remarkable mirror finish, as smooth, and flat as a katana. The case has been graced with a unique construction, which constitutes a single piece of steel constructs the back and lugs. The shape of the horns, hands, crowns, and markers is a direct reference to the distinctive form of these samurai swords. Ananta delivers the functions that are easy to see, and simple to use.

Seiko Ananta is landmark collection whose arrival heralds an important new step forward for the whole Seiko brand, as the first luxury range in the premium collections of Seiko. Seiko Ananta is the first luxury watch collection of its kind introduced in the watch world. The collection includes three mechanical calibres, two of which are new and all of them deliver outstanding level of accuracy, long term reliability, and power reserve.

With Ananta, Seiko has once again announced its long term objective to be a leading manufacture, and to offer the most advanced craftsmanship of the world. Ananta is a collection that expresses the commitment of Seiko to infinite perfection.
