The harsh winter finally shows signs of fading, and the long-awaited warm days begin to shine through the snowy landscape. The gently warm, rounded dial design and champagne gold dial color express the faint scent of spring that artisans perceive. The slim form equipped with the hand-wound movement Cal. 9S64, meticulously crafted by artisans at the Grand Seiko Studio in Shizukuishi, creates a clean look around the wrist. This model embodies the beautiful transition of the seasons in Japan.\nGrand Seiko\nManufacture\nGrand Seiko is a true manufacture that handles everything in-house, from movement development to design, manufacturing, assembly, adjustment, inspection, and shipping. In an environment where each component can be researched and developed from the material, cutting-edge technology is fused with the highest level of artisan craftsmanship.\nThe Spirit of Takumi\nThe artisans of Grand Seiko continue to endlessly pursue the essence of time. This attitude is akin to the concept of \"Do\" seen in traditional Japanese martial arts, tea ceremony, and flower arrangement. By honing their skills and deepening their spirituality, this path becomes sharper and opens up new realms. To embody the ever-changing passage of time in a watch, they strive for high precision, visibility, and aesthetic beauty in design. Creating a true ideal watch that shines eternally across generations is an endless challenge for the artisans.\nLight and Shadow\nThe Japanese delicately perceive, savor, and cherish the countless expressions created by light and shadow as time flows. The design is characterized by sharp, flat surfaces and straight lines without distortion. The mirror finish is meticulously polished by exceptional artisans. The multi-faceted cut indices and thick hands are designed to create beautiful expressions every time the light changes due to time or place, while maintaining high visibility and shining brilliantly.\nSpecifications\nExterior: Stainless Steel, Case Back: Stainless Steel and Sapphire Glass\nGlass Material: Box-shaped Sapphire\nCoating: Anti-reflective coating on the inner surface\nLumibrite: None\nCase Size: Width 37.3mm, Height 44.3mm, Thickness 11.7mm\nWrist Size (Maximum): 195mm\nClasp:\nDrive Method: Mechanical, Hand-wound\nPower Reserve: Static Accuracy:\nStatic Accuracy: Average daily deviation +5 seconds to -3 seconds\nWater Resistance: Daily life water resistance\nMagnetic Resistance: Yes\nWeight: 61 g\nGrand Seiko continues to evolve in pursuit of the essence of watches as timepieces that walk alongside life.\nThe Holy Land of Mechanical Watches: Shizukuishi High-End Watch Workshop\nThe \"Shizukuishi High-End Watch Workshop,\" which is responsible for Grand Seiko's mechanical watches, is located in Shizukuishi Town, Iwate Prefecture. It is a manufacture that consistently handles everything from the design and manufacturing of components such as the hairspring and gears, which govern the heart of mechanical watches, to assembly, adjustment, inspection, and shipping. Many skilled craftsmen, including those who have received the \"Modern Master\" and \"Yellow Ribbon Medal,\" are present, and their exceptional craftsmanship produces the world's highest quality mechanical watches. Grand Seiko's mechanical watches consist of about 200 parts, and the precision of each part greatly influences the accuracy of the finished product. The coexistence of high-precision parts manufacturing technology and the artisan skill to assemble them with adjustments down to 1\/100mm creates an environment that gives birth to numerous legendary timepieces in watch history.\nMechanical Watches\nMechanical watches are a style of watch that has been passed down unchanged since the birth of watches that use a mainspring as a power source and indicate time through the movement of hands. This drive system utilizes the force of the unwinding mainspring to rotate gears at a constant speed, and the accuracy is adjusted by a regulating and escapement mechanism composed of a \"balance wheel,\" \"anchor,\" and \"escape wheel.\" The \"anchor\" controls the rotation of the \"escape wheel\" at a constant rhythm based on the regular vibrations of the \"balance wheel.\" The \"balance wheel\" repeats a pendulum-like regular back-and-forth motion, controlling the speed at which the mainspring unwinds to be constant (i.e., regulating) and allowing it to unwind over a long period. This constant motion is transmitted to the hour, minute, and second hands, displaying the time.\nThe Pillar Supporting Accuracy: The Balance Wheel\nThe \"balance wheel,\" which is the wheel part of the balance, regulates and controls the repeated motion of the anchor, maintaining the vibration at a constant speed. It is one of the crucial parts that significantly influences the accuracy of the watch, with weight adjustments made to the 0.000001g unit to stabilize rotation. Because it is an extremely delicate part, slight temperature changes can cause contraction or expansion, leading to deformation. Therefore, in the 9S mechanical movement, the number of support pillars is increased from the usual 2-3 to 4, providing solid support and minimizing the impact of temperature differences on the shape of the balance wheel and, consequently, on accuracy. They are committed to preventing deformation, even at the cost of significantly increasing the effort required to produce the parts.\nHigh Accuracy Standards Beyond Chronometer\nThe first Grand Seiko, born in 1960, had the word \"Chronometer\" engraved on the dial as proof of passing the Swiss chronometer standards. However, you will not find the word \"Chronometer\" on today's Grand Seiko. The reason lies in the \"New GS Standards.\" Established in 1998, this standard has a higher accuracy criterion than the Swiss chronometer standards. Furthermore, there exists the \"Grand Seiko Special (GSS) Standards,\" which exceed the \"New GS Standards\" in the 9S mechanical movement. This accuracy standard can only be reached by skilled watchmakers who spend many times more time than usual on a mechanical watch, resulting in very few being produced each year.\n17-Day Certification Test\nThe 9S mechanical movement must undergo a unique certification test based on strict standards lasting 17 days. Under various conditions set at three different temperatures and six directional positions, it cannot bear the Grand Seiko crown unless the time advance or delay (daily deviation) falls within the standard values.\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%;\"\u003eDrive Method\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003eMechanical\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 Wave Automatic Correction Function\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003eNone\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 Method\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;\"\u003eSS bezel, SS body, SS case back + Sapphire Glass\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;\"\u003eBox-shaped Sapphire Glass\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;\"\u003eCrocodile\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;\"\u003eNone\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;\"\u003eStatic Accuracy: Average daily deviation +5 seconds to -3 seconds\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%;\"\u003eSpecification 1\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003e2022 Volume 1, 24 jewels, Second hand stop function\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%;\"\u003eSpecification 2\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003eCase back with lion emblem, see-through back, six-screw fixed case back\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%;\"\u003eSpecification 3\u003c\/td\u003e\n\u003ctd style=\"border-bottom:1px solid #ccc;padding:6px 10px;\"\u003eCase Size: Height 44.3mm × Width 37.3mm × Thickness 11.72mm\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¥671,000 JPY\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n```","brand":"SEIKO","offers":[{"title":"Default Title","offer_id":47586196586580,"sku":"SBGW281","price":643678.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0284\/7401\/5828\/files\/SBGW281_2.jpg?v=1787850602","url":"https:\/\/www.ippojapanwatch.com\/ja\/products\/seiko-sbgw281-japanese-mechanical-hand-wound-movement-stainless-steel-case-elegant-design-sapphire-crystal","provider":"IPPO JAPAN WATCH ","version":"1.0","type":"link"}
