Seiko Men's SNZF15J1 Dark Blue Dial Watch

SEIKO 5 - the meaning of the "5" A great marketer had the idea in the 70ies: to be a SEIKO 5, the watch has to have the following 5 (five) attributes (thus the name SEIKO 5): 1. Automatic, 2. Water resistant, 3. Shock resistant, 4. Date, 5. Day. Please note that some SEIKO 5's are in fact SEIKO 4's, if the "Day" function is omitted, then the Caliber 7S25 is used. The only difference to the normally found 7S26 is the omission of the day wheel. Also re-issues of SEIKO 5 Sports often use the 7S36 caliber. Again the 7S36 is similar to the most popular 7S26, yet it features 23 Jewels as sed to the 21 Jewels in the 7S26. Please note that all these movements beat at a rate of 21'600 bph (beats per hour) or 6 bps (beats per second). As a comparison, an ETA 2824-2 beats at 28'800 bph or 8 bps. A Miyota 82xx beats at 21'600 bph. Why do I mention these three movements? Because they are found in probably 80% of all inexpensive automatic wrist watches. A market share that is huge, yet challenged these days (2006) by an increasing share of inexpensive China Made automatic movements An automatic watch (also called a self-winding watch) is a mechanical watch, typically with a balance wheel escapement, whose mainspring is wound by the motion of the wearer's arm, instead of having to be wound manually every day. Whereas a quartz watch is powered by electricity, a mechanical watch is powered by a mainspring which must be rewound for the watch to keep time. From Humble beginnings, Kintaro Hattori’s Vision for Seiko has become reality. A consuming passion for excellence - imprinted in our Corporate passed from generation to generation. Seiko, for 125 years committed to the art and science of time. A culture of innovation connects a 19th century Tokyo clock shop with 20th century advances in timekeeping to an extraordinary 21st century "quiet revolution." Continually driven by dedication and passion, established a multitude of world’s first technologies… transforming the principles of timekeeping. The first quartz wristwatch – changed the history of time. The first Kinetic – marked a new era in quartz watch technology. In 1969, Seiko Astron, the first quartz wristwatch - was introduced. In an instant, Seiko exponentially improved the accuracy of wristwatches –And Seiko technology firmly established today’s standard in Olympic and sports timing. 1984, another celebrated first – Kinetic Technology – powered by body movement. Kinetic – a quartz mechanism with unparalleled accuracy –the driving force behind more world’s firsts. Kinetic Chronograph – the next generation of high performance timekeeping. Kinetic Auto Relay – automatically resets to the correct time. Kinetic Perpetual - combining the date perfect technology of perpetual with the genius of Kinetic Auto Relay. And now Kinetic Direct Drive – move, and the watch is powered automatically. Or hand wind it and see the power you are generating in real time. In the realm of fine watches, time is measured by Seiko innovation – A heritage of dedication to the art and science of time.
