Complications
Cazalea announces that the Grand Seiko Kodo Constant-force Tourbillon SLGT003 has been awarded the Chronometry Prize at the 2022 Grand Prix dâHorlogerie de Genève. This post celebrates a significant milestone for Grand Seiko, highlighting its first mechanical complication watch and the innovative Caliber 9ST1. Readers can learn about the unique integration of a tourbillon and constant-force mechanism on a single axis, a horological first that underscores Grand Seiko's commitment to precision and craftsmanship.
The Grand Seiko Kodo Constant-force Tourbillon is Grand Seikoâs first mechanical complication watch. At its heart is a uniquely innovative movement, Caliber 9ST1, which, for the very first time in horological history, combines a tourbillon and a constant-force mechanism as one unit on a single axis.
The watch is named Kodo, or âheartbeatâ in Japanese, after the unique motion of the two mechanisms and the sound of the rhythm it makes. The inner tourbillon carriage rotates smoothly as the balance steadily vibrates at 8-beats per second, and the outer constant-force carriage follows its rotation at exact one-second intervals to create a 16th note rhythmic feel.
The components are painstakingly finished by hand using a variety of techniques to endow the overall movement with the quiet yet enduring sparkle that is the hallmark of Grand Seiko. The case is constructed of both Platinum 950 and Grand Seikoâs Brilliant Hard Titanium to achieve a long-lasting beauty.
A true masterpiece. Cheers, Filip
