SEIKO Prospex 'Black on Black' One Hundredth of a Second Speedtimer Solar Men`s Chronograph

This particular design is powered by a new in-house solar chronograph calibre equipped with a stopwatch which measures time to the nearest 1/100th of a second. Becoming official timekeeper for Tokyo’s 1964 Olympics was a turning point in Seiko’s history when the brand began making precisely accurate professional sports timing instruments, with no prior experience. This legacy continues today as Seiko is the World Athletics Official Timekeeper since 1985, supplying timing and measurement services to more than 180 World Athletics events in every corner of the globe. The Black subdials and black – ‘black on black’ coloured dial of this particular timepiece achieve visibility and legibility due to its separate indicators for time and chronograph functions. Conveniently solar-powered; the watch charges from both natural and electric light. The hammer-shaped button allows for easier operability of the stopwatch function.
