Four new solar chronographs join the Seiko Prospex collection marking the company’s association with the World Athletics Championships to be held in Budapest, Hungary, in August, 2023.

The Seiko Prospex Speedtimer Solar Chronograph watch is 42mm-wide, 12.9mm-thick, and its lug-to-lug distance is 48.3mm, making it reasonably thick for a highly functional chronograph and proportionate to the 42mm diameter. All offer 100 meters of water resistance and 4,800 A/m magnetic resistance for peace of mind.
