Launched in 1999 as a limited edition offering of just 500 pieces, the ref. SBWA001 that we have here is one of three references, one more for Seiko (the yellow gold SBWA002) and one for Credor, that introduced Seiko’s now legendary Spring Drive movement to the market. Combining the accuracy of quartz timekeeping with the craftmanship of mechanical watchmaking the Spring Drive movement was a massive leap forward akin to what quartz watches were in 1969, also introduced by Seiko. Boasting a unique 38mm stainless steel case with an unusual integrated bracelet that attaches to the cass through a screw that punctures the case and bracelet and holds them together, the SBWA001 wears on the wrist with a unique presence, as best reflected by its unusual movement, the manual-wind spring drive cal. 7R68, which is on display behind a sapphire crystal exhibition caseback. Boasting a glossy black dial with a power reserve indicator and date aperture, the SBWA001’s display serves as a functional and legible means to display the time for this uniquely wrapped horological package.

An essential first step in Grand Seiko's development of their famed Srping drive technology, the SBWA001 paved the way for hundreds of other models and references over the last 26 or so years, with hundreds more to follow thanks to its success.
