Thanks to a balance spring and regulator integrated into the gear train, the seconds hand glides continuously, just like on a mechanical watch. On the wrist, the illusion is complete: many people mistake it for an automatic.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhy is this movement sought after?\u003c\/strong\u003e\u003cbr\u003eThe 5S21 was produced only for a very short period, around 1988-1989, and represents a technical curiosity in the history of Seiko. Collectors often consider it one of the milestones that led to the celebrated Spring Drive movement of Seiko, which revisits the principle of a perfectly fluid seconds hand. It is a rare and discreet piece.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoes this movement operate at high frequency?\u003c\/strong\u003e\u003cbr\u003eNo, the 5S21 operates at the standard quartz frequency of 32,768 Hz. Its distinctive feature does not come from a high frequency, but from its mechanical regulating system (balance spring and viscous regulator), which transforms the jerky advance of the motor into the continuous sweep of the seconds hand. It is this ingenuity, not the frequency, that makes it unique.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIs this watch suitable for a man or a woman?\u003c\/strong\u003e\u003cbr\u003eWith its 34mm round case, it is a Unisex piece, elegant on the wrist of both a man and a woman. Its Roman numeral dial and gold-plated case make it an ideal dress watch for formal wear.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWhat is the international shipping time?\u003c\/strong\u003e\u003cbr\u003eDispatch within 48 hours, international delivery within 3 to 5 days, insurance included.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u0026nbsp;\u003c\/p\u003e ","brand":"Seiko","offers":[{"title":"Default Title","offer_id":53950911283537,"sku":"950437 5S21-7000","price":1.05,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/8576\/2597\/files\/montre-seiko-spirit-vintage-plaque-or-trotteuse-glissante-1989-atelier-victor-1.jpg?v=1781091845","url":"https:\/\/ateliervictor.co\/en\/products\/vintage-seiko-spirit-gold-plated-watch-smooth-sweeping-seconds-hand-1989","provider":"Atelier Victor","version":"1.0","type":"link"}
