It conceals a rare feature: its sweep-seconds calibre, an exceptional quartz movement considered a precursor to Spring Drive. In a versatile size, it can be worn just as well on a man’s wrist as on a woman’s. A sober and refined Japanese watch, ideal for everyday wear as well as evening occasions.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003egold dial\u003c\/strong\u003e with its sunburst finish highlights a Roman numeral XII, fine applied baton indices, and the Seiko signature. Slim gold hands sweep across the dial, including a seconds hand with a particularly fluid motion. A sober and luminous dial, in the great tradition of Japanese dress watches, enhanced by the distinctive smoothness of its seconds hand.\u003c\/p\u003e\n\u003cp\u003eThis Seiko is powered by the \u003cstrong\u003e5S21 quartz calibre\u003c\/strong\u003e, a rare and sought-after movement: its seconds hand glides smoothly, like a mechanical watch, instead of ticking once per second. Thanks to a hairspring and a viscous regulator, it delivers that highly distinctive sweep, and is often described as one of the forerunners of Spring Drive technology. Produced for only a few years in the late 1980s, it was originally announced with a precision of less than 20 seconds per month. An original calibre that carries forward the heritage of Seiko, the quartz pioneer with the 1969 Astron.\u003c\/p\u003e\n\u003cp\u003eWith its \u003cstrong\u003e32mm case\u003c\/strong\u003e and very slim profile (6.8mm), and its round gold-plated shape, this vintage watch offers an elegant and versatile size, suitable for both men and women — a true \u003cstrong\u003eUnisex watch\u003c\/strong\u003e.
