Shinshu in Nagano Prefecture, where all Grand Seiko Spring Drive watches are produced, was once the main center of silk production. Drawing inspiration from that period of history, Grand Seiko’s latest models include SBGA437, SBGA439 and SBGA467. Three Spring Drive models all use silk sun pattern dials, and SBGA465, whose special dials are inspired by gleaming frost.
The four models of stainless steel cases have a diameter of 40 mm and a thickness of 12.3 mm, representing a modern interpretation of the Grand Seiko style. The case uses long-faced lugs that extend from the middle of the case and bend down to the bracelet to provide a comfortable ergonomic design. The length from the tip of one lug to the other is only 46.6 mm, and the case is designed for various wrist sizes.cheap aaa watch
The geometry of the case is emphasized by its eye-catching finish, which combines a fine-grained brushed surface with a Zaratsu polished surface with mirror-like distortion-free reflections. Three screw-fixed crowns, the case has a rated pressure of 10 bar, and a solid back cover protects the internal movement. All in all, this case is designed for reliable everyday wear.
The silk sun pattern radiates outward, capturing light from all angles. It has a soft texture, no different from the best silk, it can only be created by applying soft silver using a special silver plating method.
The sky under the moonlight at night presents alluring and ever-changing tones, perfectly captured in this midnight blue sun dial. The color oscillates between the warm blue of some light and the black of other light.
This dynamic black dial is the ideal background for diamond-cut hands and hour markers, which is particularly eye-catching against the dark sun-grain texture.
The winter in Shinshu came suddenly. Frost on the trees at night, for a short and beautiful moment, gleaming in the morning sun before melting. The fleeting beauty of this phenomenon is captured here.
Spring drive 9R65
Spring Drive combines the high torque and non-stop power source of a mechanical watch with the high precision and stability of a quartz watch. The 9R65 movement is produced in the Shinshu Watch Studio in Nagano, with an accuracy of 1 second per day. The second hand advances in a smooth and sliding manner. This is a unique feature of Spring Drive.
