Prospex Speedtimer World Athletics 2022 Limited EditionThere are just 400 pieces available worldwide of this limited edition chronograph timepiece, designed to commemorate the 2022 World Athletics Championships held in Oregon USA.Since 1985, Seiko has supported the major World Athletics championships, supplying timing and measurement services to more than 180 World Athletics events in every corner of the globe. This timepiece is inspired by the original 1964 chronograph stopwatch - becoming official timekeeper for Tokyo's high profile international sports event in 1964 was a turning point in Seiko's history. Making precisely accurate professional timing instruments with no prior experience resulted in the Seiko Watch Corporation design code of visibility, legibility and functionality.The next crucial landmark in the history of the chronograph was the creation of the Seiko Speedtimer in 1969. Thanks to its vertical clutch and column wheel, it ensured an even more precise measurement of elapsed time. Hand-assembled by Seiko's skilled watchmakers, this new Speedtimer is powered by Caliber 8R46, which, like the Caliber 6139 used in the original 1969 Speedtimer, incorporates vertical clutch and column wheel mechanisms to ensure the highest possible levels of precision and durability. The escapement is lightweight and strong, thanks to the use of MEMS technology which enhances the stability of the watch's precision. Prospex is a combination of the words 'Professional' and 'Specifications.' These timepieces are designed to be practical, reliable and durable within extreme or everyday environments for experts, sports lovers and adventure seekers alike.
