Seiko SSC935 Prospex Crystal Trophy Speedtimer Solar Chronograph

The Seiko SSC935 Prospex Crystal Trophy Speedtimer is a striking solar-powered chronograph that celebrates Seiko’s rich motorsport and sports timing heritage. Combining performance and refined design, this special edition features a brilliant sunray blue dial inspired by the sparkle of a crystal trophy awarded to athletes, offering both elegance and sporty character in one timepiece.

Powered by Seiko’s Solar Caliber V192 movement, the SSC935 eliminates the need for battery changes, converting light into energy and providing up to 6 months of power reserve once fully charged. The chronograph tracks elapsed time up to 60 minutes in precise 1/5-second increments, while the 24-hour sub-dial, power reserve indicator, and date display add real-world utility.

Designed for reliability and everyday wear, it’s built with a stainless steel case and bracelet, curved anti-reflective sapphire crystal, and 100 m water resistance — all anchored by a bold tachymeter bezel. With luminous hands and markers, this Prospex Speedtimer excels in legibility and performance wherever your day takes you.
