Seiko Black Dial Stainless Steel Leather Quartz Men's Watch SUN057

PROSPEX SERIES: In 1964, Seiko announced itself on the world stage of sports timing technology with a whole new generation of timing and scoring devices that set a new standard. The multi-sport suite of timing, scoring and display systems comprised no fewer than 1,278 devices in all. Ever since, the challenge of sports has inspired Seiko to create new technologies to serve the needs of true sports enthusiasts worldwide. Seiko pioneered several features in diverÕs watches that are now widely accepted as setting the global standard, including the ÔaccordionÕ or corrugated style strap, the wide arrowshaped hands for extra legibility, and the two-piece case construction for added security. Similarly, in aviation watches, Seiko invented the trigonometric slide rule that allows pilots to make complex calculations in flight.
