Grand Seiko Lifts The Watch Sports Precision Whirlwind: Spring Drive Sbga391 And Sbge245 Sports Limited Edition Grand Debut

Japan’s top watch brand, GrandSeiko, has always been a representative of high-quality watches and clocks, and has continuously created pioneering works in watchmaking technology that can shake the watch industry. Since the announcement of brand independence in 2017, GrandSeiko has actively opened the door to the new world, not only emphasizing the brand personality and expanding the multi-faceted design, but also full of topical innovative designs and cross-border cooperation. Offensive mainstream watch market.

GrandSeikoSpringDriveGMTSBGE245 stainless steel case, 44 mm diameter, GMT, date display, power reserve display, fast time zone adjustment, 9R66 SpringDrive GMT movement, 72-hour power reserve, 30 stone, average day difference ± 1 second, double-arc sapphire crystal mirror surface (inside Anti-glare coating), lockable crown, screw-in back cover, two-way rotating bezel, 20 bar water resistance, with replaceable silicone strap, limited to 600 pieces worldwide.
 This year can be said to be a great year for GrandSeiko. In addition to the 20th anniversary of the 9S movement and the 25th anniversary of the 9F movement, a number of commemorative limited edition models are listed. The 9R movement equipped with SpringDrive is also taking advantage. GrandSeiko senior designer-Kubo Shinichiro’s sports watch, through Kubo’s interpretation of ‘power’, makes its models naturally blend with the modern rigid appearance of the SpringDrive hands naturally sliding.

Inspired by the natural beauty of the birthplace of the SpringDrive movement
 With the change of consumption trends, consumers value the value of watches not only limited to daily wear, but also pay more attention to sports watches with practicality and functionality. GrandSeiko is aware of this demand, and has continued to design and develop sports watches in recent years. Adhering to the essence of GrandSeiko’s ‘precision’, ‘high-quality’ and ‘easy to understand’, Kubo Shinichiro, who has been the designer of GrandSeiko since 2003, has invested a lot of effort in the design of sports watches, as in the design of GrandSeiko For a diving watch, I went to Okinawa to experience diving for this purpose, turning every function that divers pay attention to into design elements, and fully showing the importance that GrandSeiko attaches to the design of watches.

 The Asian limited edition SBGA391 equipped with 9R65 SpringDrive movement was released by Kubo Shinichiro this time. In addition to incorporating the sense of power especially emphasized by sports watches in the design, the design inspiration of the faceplate is derived from the birthplace of SpringDrive movement. The Asi Valley in Nagano Prefecture uses the special blue-green color of the Asi River as the main color. The diamond pattern embossed on the face plate is like the sparkling waves shining on the clear blue-green stream, and it displays different colors with the change of light and shadow. . In addition to the 200-meter diving watch function, the power reserve is also presented in 3 different blue colors.
Ocean-themed experience on the wrist
 The SBGE245, also designed by Kubo Ichiro, uses the theme of ‘ocean’ to transform the image of watching the beautiful dawn on the deck of a luxury passenger ship into a peach-colored panel carved with slender radial lines, and the power reserve scale is as bright as possible The sunrise on the horizon is full of vitality. Equipped with SpringDriveGMT movement, with 24-hour graduated bi-directional rotating bezel coated with LUMIBRITE luminous paint, it can display 3 time zones at the same time. In order to strengthen the overall sports design image, in addition to the metal chain strap, a replaceable orange silicone strap is also provided, which means the light and shadow of morning and evening, echoing the unique face plate. The strap ring is also equipped with a ‘lion pattern’ Chapter ‘, achieving a full and bright design sense.

 In addition to the well-designed sporty appearance, the two models launched this time use a sliding travel design, which captures the flow of light in the sliding movement of the hands at a uniform speed, faithfully presenting the continuous, accurate, and silent characteristics of nature. It is not like a flat and regular ticking sound when a mechanical watch is in operation, nor is it a standard one-by-one vibration of a quartz watch. Perfectly show the time trajectory of almost hypnosis.
Exclusive process technology secures the 9R SpringDrive movement
 The continuous pursuit of innovation and progress, the development of watches that can operate continuously is the goal that GrandSeiko has been pursuing. In 2004, based on the original SpringDrive movement, GrandSeiko released the 9R65 SpringDrive movement, which has made great progress in terms of durability and durability. The operation also jumped from 48 hours of hand-powered models to 72 hours of automatic-winding power. paragraph.

GrandSeiko9R65SpringDrive movement
 The important soul of the 9R SpringDrive movement is a speed control mechanism called ‘three-energy regulator’, which uses three kinds of energy: electrical energy, mechanical energy and electromagnetic energy to adjust the speed of loosening the clockwork and establish the rule of pointer operation. The 9R SpringDrive movement is powered by the mainspring and uses the movement of the wrist as the power generated by the winding of the mainspring to start the integrated circuit (IC) and the quartz oscillator to generate electricity. At the same time, the integrated circuit (IC) compares the quartz oscillator with the transmission Signal and the speed of the magnetic car, when the speed of the magnetic car is too fast, it will intermittently apply electromagnetic braking force to precisely control the speed of the gear to ensure the precise operation of the pointer. Combining the high torque of the mechanical movement with the high-precision integrated circuit control system of the electronic watch, the 9RSpringDrive movement can simultaneously have the functions of automatic, high torque and high accuracy, which is a major process in dominating the watch industry. Results.

SpringDrive has the same power source as the mechanical movement and the accuracy of the quartz movement. It uses the power of the clockwork to rotate the magnetic car. The magnetic car and the coil can bring power to start the IC and the quartz oscillator; the quartz oscillator will vibrate the frequency signal. Sent to the IC, so that the IC adjusts the speed of the magnetic car with reference to the signal of the quartz oscillator to maintain accurate travel time.
Over the years, GrandSeiko has achieved glory today
 After many years of polishing, GrandSeiko will eventually emerge after independence. Adhering to the consistent spirit of staff and the heritage of GrandSeiko’s professional staff, GrandSeiko will move forward in the direction of more innovation and create more amazing models. With a new attitude, watch with watch fans to belong to GrandSeiko. The glory of the times.
