Winner Watch Grand Seiko Kodo Tourbillon

 

Thursday 10 November, was held at the Théatre du Léman in Geneva the award ceremony of the Grand Prix d’Horlogerie de Genève 2022 with Grand Seiko Kodo Tourbillon as a very important protagonist.

Fifteen timepieces awarded for specific categories and five other awards were awarded for a number of other watchmaking achievements.

A Grand Prix Prize was awarded to the absolute best watch in all categories.

The jury of 30 experts selected the Grand Seiko Kodo Constant-force Tourbillon as the winner of the “Chronometry” Award, which recognizes the timepiece’s excellence for its high-precision timekeeping performance.

Grand Seiko Kodo Constant-force Tourbillon

The Grand Seiko Kodo Constant-force Tourbillon is Grand Seiko’s first mechanical complication watch.

It’s characterized by a unique and innovative movement, the Calibre 9ST1, which, for the first time in watchmaking history, combines a tourbillon and a constant force mechanism as a single unit on a single axis.

The watch was called Kodo, which in Japanese means heartbeat, because of the unique movement of the two mechanisms and the sound that the rhythm creates.

Tourbillon System

The tourbillon’s internal system rotates without friction, while the balance vibrates evenly at 8 oscillations per second, and the outside at constant force follows the rotation at exact intervals of a second to create a rhythmic sensation of 16 notes.

Each main component is finished strictly by hand by means of a variety of techniques aimed at highlighting the movement as a whole thanks to the discreet and durable brilliance at the same time, which is the hallmark of Grand Seiko.

The case construction makes use of both 950 platinum and Grand Seiko’s Brilliant Hard Titanium to achieve a long lasting beauty.

I would like to express my sincere gratitude to the members of the jury who recognized this achievement to the team of our engineers and watchmakers, led by Takuma Kawauchiya”.
