For aficionados of wristwatch craftsmanship, the journey of Grand Seiko’s Spring Drive is a tale of relentless pursuit, innovation, and precision. Born from a visionary concept in the 1970s, the Spring Drive sought to amalgamate the enduring force of a mainspring with the sophistication of electronic watchmaking technologies, thereby redefining the standards of accuracy in mechanical timepieces. Over two decades of meticulous development culminated in the emergence of the 9R movement, the heartbeat of all Grand Seiko Spring Drive watches today.
In September 2004, the horological world witnessed the dawn of a new era as Grand Seiko unveiled the inaugural Spring Drive watch, a testament to unrivalled precision, automatic winding, and an impressive 72-hour power reserve. Fast forward to 2024, a pivotal year marking the 20th anniversary of this monumental achievement, where Grand Seiko proudly introduces two new creations that pay homage to the illustrious legacy of Spring Drive.
