The 9F quartz is the result of questioning the essence of a wristwatch that seems so obvious.\n・Instantly switching instant date calendar\n・A power source for moving thick and bold hands like a mechanical watch\n・Improved accuracy in indicating seconds\n・High airtight structure to enhance oil retention\nThe 9F quartz, which incorporates numerous new concepts that were unthinkable in conventional quartz, overturns the previous norm of \"thin and light quartz\" and boasts world-class performance.\n【The birthplace of quartz watches and Spring Drive: Shinshu Time Artisan Workshop】\nGrand Seiko is a true \"manufacture\" that handles everything from movement design to development, manufacturing, assembly, adjustment, inspection, and shipping in-house, creating watches that fuse cutting-edge technology with the highest level of craftsmanship. The \"Shinshu Time Artisan Workshop,\" responsible for Grand Seiko's quartz watches and Spring Drive, is located in Shiojiri, Nagano Prefecture. In just five years since the introduction of Grand Seiko's quartz, it completed the world's highest-level quartz that exceeded previous norms while also creating the dream mechanism Spring Drive, developed over more than 20 years, showcasing innovative ideas and manufacturing techniques.\n【Instantly switching \"instant date calendar\"】\nThe 9F quartz employs an \"instant date cam\" that works in conjunction with a \"date gear,\" and an \"instant date lever\" that operates with that movement. As the \"date gear\" rotates, it gradually bends the spring of the \"instant date lever\" to store energy, and when the cam reaches a certain position, the spring is instantly released, causing the date display to switch instantly. While instant date calendars have been seen in mechanical watches with strong torque, Grand Seiko is the first to implement this in a quartz watch.\nThe task of aligning this switch moment with midnight is done by skilled assembly artisans, and it is set as a standard to ensure that the calendar does not switch before midnight, within a range of 5 minutes before midnight.\n【\"Regulator switch\" for precision adjustment even in quartz】\nMechanical watches have mechanisms for fine-tuning accuracy, but generally, quartz watches cannot be finely adjusted even when the back cover is opened. However, the 9F quartz has a \"regulator switch\" that allows for precision adjustment. After using it for several years, when tendencies of gaining or losing time become apparent, this switch can be used to correct the accuracy. As you use the watch for many years, you will understand its \"quirks,\" and by making adjustments to suit its personality, it becomes a watch that can accompany you for a longer time. However, the quartz crystal oscillator used in the 9F quartz is of the highest quality, having undergone special testing and aging, so the need for the \"regulator switch\" is rare. This is one of Grand Seiko's thoughtful considerations.\n【Thick and heavy hands accurately keep time with the \"twin pulse control motor\"】\nIn quartz watches, which generally have weaker torque than mechanical watches, it is not possible to move thick and heavy hands, so typically thin hour and minute hands are used. However, Grand Seiko's quartz models are equipped with thick and bold hands, reminiscent of the first Grand Seiko. To accurately move such hands, the 9F quartz is equipped with a \"twin pulse control motor\" that can move heavy hands while saving energy. While the second hand of a normal quartz moves in one step per second, the 9F quartz moves in two steps per second. This is because it efficiently sends two signals per second to achieve high driving force and energy efficiency to turn thicker hands. By increasing the signals, it increases the axis torque from the rotor, allowing even thick hands to be moved. Of course, this two-step movement is not perceivable to the naked eye and appears as a single step like conventional quartz watches. Furthermore, unlike other quartz watches, it employs a unique method of temperature compensation using ultra-low power. Typically, quartz watches do not have temperature compensation programs for monthly accuracy. Additionally, if a temperature compensation program is included, it requires significant power for control, which shortens battery life. To solve this problem, the 9F quartz adopts ultra-low power temperature compensation. By driving the unique \"twin pulse control system\" while reducing power consumption of the IC, it achieves about twice the driving force of conventional systems and a longer battery life of about three years compared to typical quartz watches.\n【\"Crystal oscillator\" aged for three months】\nThe 9F quartz achieves high precision of ±10 seconds per year by using only crystal oscillators that have been selected after three months of aging, ensuring stable performance. The crystal oscillator vibrates 32,768 times per second, and the accuracy of quartz watches is determined by whether this frequency can be maintained. There are individual differences in crystal oscillators, and some may fail to maintain stable frequencies due to environmental changes or aging. Additionally, even initially high-precision crystal oscillators may experience frequency changes over the years of use, leading to gains or losses in time. Focusing on this point, Grand Seiko was the first in the world to adopt an \"aging\" method that ensures the frequency stabilizes before installation. The aging process, which involves applying a constant voltage and artificially providing voltage for selection, lasts for three months. Only crystal oscillators that pass this standard are installed in the 9F quartz.\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd colspan=\"2\" style=\"font-weight:800;padding:8px;background:#d9d9d9;\"\u003eSpecifications\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #5d5d5d;font-weight:600;padding:6px 10px;width:35%;\"\u003eWeight\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003e134g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #5d5d5d;font-weight:600;padding:6px 10px;width:35%;\"\u003eDrive Type\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003eQuartz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #5d5d5d;font-weight:600;padding:6px 10px;width:35%;\"\u003eRadio Automatic Correction Function\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #5d5d5d;font-weight:600;padding:6px 10px;width:35%;\"\u003eDisplay Type\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003eAnalog\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #5d5d5d;font-weight:600;padding:6px 10px;width:35%;\"\u003eCase\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003eStainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #5d5d5d;font-weight:600;padding:6px 10px;width:35%;\"\u003eGlass\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003eSapphire Glass (Anti-reflective coating on the inner surface)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #5d5d5d;font-weight:600;padding:6px 10px;width:35%;\"\u003eBand Material\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003eMetal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #5d5d5d;font-weight:600;padding:6px 10px;width:35%;\"\u003eBand (Adjustable)\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003eScrew type\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #5d5d5d;font-weight:600;padding:6px 10px;width:35%;\"\u003eAccuracy\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003e±10 seconds per year\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #5d5d5d;font-weight:600;padding:6px 10px;width:35%;\"\u003eSpecifications\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003eBack cover: Screw-back with lion emblem\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #5d5d5d;font-weight:600;padding:6px 10px;width:35%;\"\u003eColor\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003eDial: Blue\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border-bottom:1px solid #5d5d5d;font-weight:600;padding:6px 10px;width:35%;\"\u003eList Price\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003e¥363,000 JPY\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n```","brand":"SEIKO","offers":[{"title":"Default Title","offer_id":47586196947028,"sku":"SBGX265","price":351913.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0284\/7401\/5828\/files\/SBGX265_1.jpg?v=1787850622","url":"https:\/\/www.ippojapanwatch.com\/ja\/products\/seiko-sbgx265-premium-quartz-movement-elegant-stainless-steel-case-sapphire-crystal-water-resistant-100m","provider":"IPPO JAPAN WATCH ","version":"1.0","type":"link"}
