DescriptionThe Grand Seiko Reference SBGR307, part of the esteemed Heritage Collection, showcases a harmonious blend of traditional aesthetics and cutting-edge horological engineering. Encased in a robust stainless steel structure, the watch measures 42.0mm in diameter, 47.9mm in lug-to-lug length, and 13.1mm in thickness. This case is meticulously crafted to ensure a balance between presence on the wrist and comfort. The stainless steel extends to the bracelet, featuring a three-fold clasp with a secure push-button release, designed for a perimeter of 205mm, providing a perfect fit for most wearers. A dual-curved sapphire crystal, treated with an anti-reflective coating on the inner surface, protects the dial, ensuring optimal legibility while minimizing glare. The case back is a see-through screw-down design, offering a captivating view of the intricate movement within.

At the heart of the SBGR307 lies the Caliber 9S68, a self-winding mechanical movement with manual winding capability. This movement is a testament to Grand Seiko's commitment to precision, boasting a mean daily rate of +5 to -3 seconds. It is regulated in six positions to ensure high accuracy. The Caliber 9S68 incorporates the latest in hairspring technology, coupled with an escapement developed through Micro-Electro-Mechanical Systems (MEMS) technology, achieving both high accuracy and stability. This advanced movement provides a power reserve of approximately 72 hours, or three days, reducing the need for frequent winding. The watch's functionality extends to its water resistance, rated at 10 bar, making it suitable for everyday wear. Furthermore, it possesses a magnetic resistance of 4,800 A/m, safeguarding the movement against the detrimental effects of magnetic fields. The incorporation of 35 jewels within the movement helps to minimize friction and wear, enhancing the longevity and reliability of the timepiece.
