SEIKO PROSPEX COLLECTION: Seiko pioneered several features in diver's watches with caliber number 4R36 that are now widely accepted as setting the global standard, including the "accordion" or corrugated style strap, the wide arrow shaped 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.
