Who doesn’t recognize a Grand Seiko watch? It’s been around since the 1960s—the brand established in Japan, a country known for high-quality products. The companies’ philosophy is to express the “Nature of Time.” They believe that time is a never-ending quest. The team continues to search for perfection. Every design of their watch considers this movement of light and shadow as the nature of time. Grand Seiko watches are a representation of the continually moving of time. It is dynamic and grand. The brand’s artisans make sure that every piece of the watch is precise, legible, durable, and beautiful. They have three functional watch movements: the Spring Drive, Mechanical, and Quartz. The Grand Seiko Spring Drive is a combination of a mechanical and electronic watch movement. The Mechanical watch uses the mainspring for power and speed regulation. But, the Quartz uses a battery to work. With about sixty years of existence, the Grand Seiko team has valued strict standards in every detail.
The History of Grand Seiko Watch Company
In the 1960s, Grand Seiko created a watch with 45 hours of reserved power and a 3180 caliber. It has the most accurate seconds Japan watches during that time. The brand aims to excel among luxury watches. This goal has inspired designers and engineers to create the ideal timepiece. In 1964, Grand Seiko introduced the Self-dater watch. It has an improved 50 meters of water resistance and a calendar function. If you think of it, a calendar and watch on your wrist is a handy accessory in those years. In the same decade, they developed the lion inspired design. The company created its very first Quartz watch in 1988. All the watch parts were made and assembled in the company’s factory. In 1993, the 9F83 caliber powered the Quartz watch. It has instant date change, auto-adjust, twin pulse control system, and a protective shield. After working for 20 years, a team led by Engineer Yoshikazu Akahane created the Spring Drive watch in 1999. They achieved it after producing over 600 prototypes.
Grand Seiko Spring Drive Watch
The critical element of Spring Drive is its power source and control system. It is a combination of mechanical and electronic. The mainspring keeps the watch working. After turning the crown or moving the wrist, the mainspring stores energy. As the spring unwinds, it moves the watch’s hands. There is no need for a battery. To control the Spring Drive watch hand, it has a Tri-synchro regulator. It uses three energies. First is the power from the mainspring, second is the electrical power from the glide wheel, and last the electromagnetic force to apply the brake when the glide wheel is moving too fast. This craftsmanship made the timepieces precise. With a Grand Seiko Spring Drive, you have the nature of time at your wrist. The Spring Drive has about 200 to 300 manually assembled components. The hand of this watch collection moves silently and smoothly. It doesn’t push back and forth but with a glide motion. The modern Spring Drive has a whopping 72 hours of energy reserved. Even if you don’t use it on the weekend, you don’t have to adjust the time now and then.
9R Caliber Spring Drive Watches
The Manual 9R01 Caliber Spring Drive Model has the most extended power. It has surpassed the Spring Drive 72 hour benchmark by adding 120 hours more. Even if you don’t use it for a week, it will stay working. It has manual winding, a ±0.5 second accuracy per day, a display for power reserve, a separate hour hand adjust, and 56 jewels.
The standard of Spring Drive is the Caliber 9R65 watch model. With its automatic and manual winding and boasting a 3-day power reserve. It features a display showing the remaining power, ±1 second a day accuracy, and 30 jewels.
In 2006, two years after the 9R65, they released the Caliber 9R66. The first Spring Drive model with the Greenwich Mean Time (GMT) Function is the Caliber 9R66. It has the same specification as the Caliber 9R65 except that it has a dual time and a display for 24-hour.
The Caliber 9R86 is an automatic watch with 72 hours power reserve. It also has the GMT function and a chronograph. The accuracy of this model is also ±1 second a day. It has an added time difference adjustment function interrelated with the date display.
Spring Drive is one of the best watch innovations of Grand Seiko by combining mechanical power and electronic accuracy. The brand has already proven itself as one of the leading luxury watch manufacturers. But they continue to improve their watch technology. Wearing a Grand Seiko Spring Drive reminds you of time. It was continuously moving and represented through light and shadow.
