Seiko bases this collection on the post-war era, when people became more focussed on technology instead of tradition. In 1963 Seiko launched the Sportsmatic 5 models. A mechanic watch provided with all the comforts. The 5 stands for 5 functional characteristics of the watch; exact date display, water resistant, automatic winding, sunken crown and durable materials. The current Seiko 5 collection is just as progressive, no matter what time zone it is in.
