Grand Seiko has introduced two limited-edition models from its Heritage Collection. These watches, SLGW004 and SLGW005, honor the iconic 45GS, first launched in 1968. Equipped with the latest Caliber 9SA4 mechanical movement, these models will be available starting November 9th, 2024.
A Historical Milestone: The 45GS
In 1968, Grand Seiko made a significant mark in horology with the introduction of the 45GS. This model featured the brand’s first 10-beat manual-winding high-beat movement, Caliber 4520. Collectors highly valued this movement for its accuracy and stability. The 45GS design followed the “Grand Seiko Style,” emphasizing clarity, simplicity, and elegance.
Reimagining a Classic: The 2024 Revival
Grand Seiko has meticulously reimagined the 45GS for 2024, blending original design elements with modern technology. The new models, SLGW004 in stainless steel and SLGW005 in 18K yellow gold, demonstrate the brand’s dedication to preserving its heritage while advancing watchmaking.
The stainless steel SLGW005 model is priced at 1,342,000 JPY, limited to 1,200 pieces worldwide. Meanwhile, the 18K yellow gold SLGW004 model, priced at 4,235,000 JPY, is even more exclusive, with only 200 pieces available globally. Both models maintain the original proportions of the 1968 version, with a 38.4mm case diameter and a 10.4mm thickness.
Advanced Movement: Caliber 9SA4
Powering these timepieces is the Caliber 9SA4, a manual-winding mechanical movement introduced at Watches and Wonders Geneva 2024. Operating at a high frequency of 36,000 vibrations per hour (10 beats per second), this movement ensures exceptional accuracy. Grand Seiko’s innovative “Dual Impulse Escapement” and “Twin Barrel” system contribute to an impressive 80-hour power reserve.
Moreover, the Caliber 9SA4 offers a refined winding experience with smooth feel and audible feedback. Inspired by nature, particularly the wagtail bird (“Sekirei”) found near the Shizukuishi Watch Studio, the movement’s design is both functional and artistic. The transparent case back allows collectors to admire the intricate movement, including the components that interact like a wagtail pecking.
Design and Craftsmanship
Grand Seiko stayed true to the original aesthetic of the 45GS with models SLGW004 and SLGW005. The flat, mirror-polished case with sharp edges remains a hallmark of the Grand Seiko Style. The dial, faithful to the 1968 design, includes the “SEIKO” logo at 12 o’clock and the “GS” logo at 6 o’clock. Additionally, it displays “HI-BEAT” and “36000,” indicating the movement’s high frequency. Modern manufacturing techniques have enhanced the brilliance of these models.
The stainless steel SLGW005 comes with a matching stainless steel buckle, while the 18K yellow gold SLGW004 features a gold buckle. Both watches are equipped with a box-shaped sapphire crystal with an anti-reflective coating on the inner surface, ensuring durability and clarity.
Conclusion
The Grand Seiko Heritage Collection 45GS limited edition models, SLGW004 and SLGW005, celebrate the brand’s rich history and continuous innovation. These watches offer collectors the opportunity to own a piece of Grand Seiko’s legacy, combined with modern horological advancements. Their historical significance, meticulous craftsmanship, and cutting-edge technology make these models valuable additions to any collection.
