Grand Seiko's chronograph watches showcase the brand's technological prowess

　Grand Seiko is one of Japan's top watch brands. Since its launch in 1960, Grand Seiko has released numerous models that combine precision, durability, and aesthetics at high levels. In particular, the 44GS, released in 1967, was a milestone in establishing the "Seiko Style," a design grammar that embodied a uniquely Japanese aesthetic, and has had a profound influence on subsequent Seiko and Grand Seiko models.

　For a long time, Grand Seiko's lineup lacked models equipped with complicated mechanisms, but in 2002, a mechanical model equipped with a GMT function was introduced, marking a path toward greater functionality. Furthermore, in 2007, the company released the Spring Drive movement Cal. 9R86 equipped with a chronograph, followed in 2022 by the long-awaited mechanical chronograph movement Cal. 9SC5. For Grand Seiko, which has consistently strived for higher precision, the chronograph is the perfect platform to fully demonstrate its performance. Its introduction led to a diversification not only in terms of functionality but also in design, drawing attention from enthusiasts who prefer sportier watches.

　This time, we will introduce four Grand Seiko chronograph models, all of which feature original designs and durable chronograph mechanisms, and are masterpieces that reflect the brand's philosophy.

　We will introduce some noteworthy Grand Seiko chronograph models from the current lineup.

Grand Seiko "Evolution 9 Collection Tentagraph" Ref. SLGC001

　The first mechanical chronograph in Grand Seiko history. The name "TENTAGRAPH" embodies the meanings of 10 beats per second, a three-day power reserve, and an automatic chronograph.
　The deep blue dial features a embossed design inspired by the majestic Mount Iwate as seen from Grand Seiko Studio Shizukuishi, and features a small seconds hand at 3 o'clock, a 12-hour counter at 6 o'clock, and a 30-minute counter at 9 o'clock. The bezel, which is decorated with a tachymeter, is made of ceramic.

　Although the case is voluminous, the use of bright titanium makes it lightweight, and the design, which follows the unique design grammar of the Evolution 9 style, improves the wearing comfort.

　The Caliber 9SC5 featured in this model is based on the Caliber 9SA5, which features a dual impulse escapement, free-sprung balance, and twin barrels. While inheriting its high practicality, it adds a chronograph mechanism with a column wheel, vertical clutch, and a triple-pronged hammer that ensures reliable reset.

Grand Seiko "Sports Collection Caliber 9R 20th Anniversary Limited Edition" Ref. SBGC275

　Spring Drive is Seiko's unique movement, which uses an IC and a quartz crystal to control the power generated by the mainspring. This limited edition model was created to commemorate the 20th anniversary of the birth of Grand Seiko's exclusive Spring Drive movement, Cal. 9R.

　The vibrant red of the dial is inspired by a summer morning when sunlight shines on the peaks of the Hotaka mountain range, and the bold embossed pattern on it is reminiscent of a lion's mane. This model is equipped with chronograph and GMT functions, with counters at the 2 o'clock and 4 o'clock positions, and a 24-hour display on the sapphire crystal-covered bezel.

　The voluminous case, composed mainly of flat surfaces, gives a powerful impression, while the use of bright titanium makes it lightweight. The distinctive lug design is inspired by the front paws of a lion.

　The Cal. 9R96 is a highly accurate movement that has been specially adjusted from the automatic Spring Drive Cal. 9R86. As proof of this, an 18K yellow gold medallion is set on the automatic winding rotor.

Grand Seiko "Evolution 9 Collection Chronograph GMT" Ref. SBGC251

　This sporty model with a GMT function is based on the Seiko style that defines Grand Seiko design, and employs the unique design grammar, Evolution 9 Style, which has evolved in terms of aesthetics, visibility, and wearability.

　Although it is equipped with a chronograph, GMT, power reserve indicator, and date display, the dial is not cluttered and is highly legible, allowing you to instantly check the desired display. The GMT hand is colored light blue to avoid confusion with the other hands and is the same color as the "GMT" lettering at 6 o'clock. Using the 24-hour notation around the outer edge of the dial and the rotating bezel, it is possible to display the time in up to three time zones simultaneously.

　The bright titanium case features sharp lines and a discreet crown guard. The short, thick push buttons prevent snagging on clothing and ensure a good contact area with the fingertips, improving operability.

　The Caliber 9R86 is an automatic Spring Drive movement with a power reserve of approximately 72 hours. It operates with high accuracy of ±15 seconds per month, and the second hand moves smoothly in a sweeping motion.

　The design, featuring large push buttons in a simple case with the calmness that is characteristic of Grand Seiko, was Grand Seiko's first chronograph, released in 2007. The push buttons, reminiscent of stopwatches used for timing sports, give the watch the feel of a precision measuring instrument. The buttons are screwed in to prevent malfunctions.

　The champagne-colored dial features a 30-minute counter at 2 o'clock and a 12-hour counter at 4 o'clock, and the layout allows for easy reading of the time even from the cuff. The red hand at the tip is the GMT hand, which, together with the 24-hour display around the outer edge of the dial, indicates the time in a second time zone.

　The Caliber 9R86 chronograph is controlled by a column wheel that ensures reliable operation and a vertical clutch that prevents the hands from jumping, and is equipped with a READY/START mode that minimizes measurement errors when the push button is pressed. This model is a representative example of Grand Seiko's chronographs, allowing you to fully enjoy the fun of measuring.
