Prospex Speedtimer Solar Chronograph - SSC913

Story

The world’s first self-timing watch, reinvented with innovative solar technology

In 1969, Seiko revolutionized the watchmaking world with the groundbreaking Caliber 6139 “Speedtimer,” the first-ever automatic chronograph to hit the market. The maverick didn’t just tick, it roared, captivating luminaries like Pink Floyd’s Nick Mason and Bruce Lee—even venturing into the final frontier during the ‘73 Skylab 4 mission training.

Fast forward over fifty years, and Seiko is paying homage to the model that put them on the map with the reissued Prospex Speedtimer Solar Chronograph. Sporting the original two-tone black and red bezel and supercharged with a six-month power reserve, water resistance up to 100M, and LumiBrite for low-light visibility, this watch is Seiko at its best. It’s a powerhouse combo of winning design and forward-thinking innovation that continues to set industry standards worldwide.
