Today, Spring Drive has become synonymous with Grand Seiko, but its story began here before Spring Drive ever appeared on a Grand Seiko dial.\u003c\/p\u003e\n\u003cp\u003eThe SBWA001 is also an incredibly distinctive watch in its own right. Its unconventional stainless-steel case flows directly into one of the most unusual integrated bracelets Seiko has produced, while the exhibition caseback reveals the first-generation Caliber 7R68 Spring Drive movement underneath.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHistory:\u003c\/strong\u003e\u003cbr\u003eThe story of Spring Drive began with Seiko engineer Yoshikazu Akahane, who envisioned a watch combining the motive power of a traditional mainspring with the precision of electronic regulation. Development formally began in 1982, but creating a system efficient enough to operate solely from the tiny amount of electricity generated by the unwinding mainspring proved extraordinarily difficult. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eAfter multiple development attempts, Seiko finally presented a functioning Spring Drive at Baselworld in 1998. The following year, the technology reached commercial production, and on December 11, 1999, the first Caliber 7R68 Spring Drive was released. Seiko itself describes Spring Drive as the world's first watch technology to combine mechanical driving force with quartz regulation. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe stainless-steel SBWA001 was limited to 500 pieces and retailed for ¥250,000 before tax.
