The Seiko Prospex SSC507 is a men's solar-powered chronograph watch featuring a world time function that displays the current time in 25 cities around the globe. Powered by Seiko's V195 solar quartz caliber, it recharges from any light source and holds a full charge for up to six months, eliminating the need for battery replacements.

The 42mm stainless steel case houses a rich blue dial with LumiBrite luminous hands and markers for low-light visibility. A scratch-resistant sapphire crystal protects the dial, and a screw-in caseback adds durability. The chronograph function measures elapsed time up to 24 hours in 1/5-second increments with split-time capability. Additional functions include a daily alarm, a date window at the 4 o'clock position, and a power reserve indicator at 12 o'clock. The watch is water resistant to 100 meters and comes on a stainless steel bracelet with a deployant clasp.
