Grand Seiko, 39.1mm, Calibre 9F83 High Accuracy Quartz, SBGT241 25TH Anniversary Limited Edition

Grand Seiko Heritage Collection Ref. SBGT241 (9F83-0AM0) is a highly collectible limited edition created in 2018 to celebrate the 25th anniversary of Grand Seiko's legendary Calibre 9F quartz movement. Limited to just 1,500 pieces worldwide, the SBGT241 reinterprets the design of the original Grand Seiko model that debuted the 9F movement in 1993, combining traditional Grand Seiko styling with exceptional high-accuracy quartz engineering. The distinctive silver dial features an intricate repeating pattern formed from the “GS” and “9F” characters, along with a five-pointed gold star above 6 o'clock signifying the specially adjusted high-precision movement. A blued seconds hand provides a subtle contrast, while the beautifully proportioned 39.1mm stainless steel case and matching bracelet deliver the restrained elegance associated with the Heritage Collection. At its heart is the exceptional Grand Seiko Calibre 9F83 High Accuracy Quartz movement. For this anniversary edition, specially selected quartz oscillators were used to achieve an enhanced accuracy of approximately ±5 seconds per year, compared with ±10 seconds per year for the standard Calibre 9F83. The movement also provides both day and date displays, combining remarkable precision with practical everyday functionality.
