Seiko Prospex SSC917 Speedtimer Solar Chronograph Black Series Watch

The Seiko Prospex SSC917 Speedtimer is a distinctive solar-powered chronograph from Seiko’s Prospex Black Series, designed with a dark, technical appearance inspired by the brand’s history of precision sports timing. The watch features a black hard-coated stainless-steel case and bracelet, a black and grey dial, and a black tachymeter bezel, creating a bold monochromatic design suited to both everyday wear and outdoor-inspired styling.

At the heart of the SSC917 is Seiko’s V192 solar calibre, which converts light from both natural and electric sources into energy. Once fully charged, the movement provides approximately six months of operating time, while an overcharge prevention function helps protect the movement. The watch also includes a power reserve indicator, allowing you to monitor its remaining energy without relying on regular battery changes.

The Speedtimer’s chronograph can measure elapsed time up to 60 minutes in 1/5-second increments, with split-time functionality. A dedicated 24-hour hand, small seconds hand, and practical date display add further functionality to the dial. The tachymeter scale around the bezel complements the chronograph design and reinforces the watch’s motorsport-inspired Speedtimer character.

The SSC917 is built with a curved sapphire crystal featuring anti-reflective coating on the inner surface, providing excellent scratch resistance and improved legibility. Seiko also applies LumiBrite to the hands and indexes for visibility in darker conditions. The stainless-steel bracelet uses a three-fold clasp with push-button release, while the screw case back contributes to the watch’s robust construction.

Measuring 39 mm in diameter, 13.3 mm thick, and 45.5 mm lug-to-lug, the SSC917 offers a substantial but relatively compact wrist profile, with a weight of approximately 161 g. Its 100-meter / 10-bar water resistance makes it suitable for everyday use and a range of outdoor activities. For anyone looking for an original Seiko Prospex watch in Kenya with solar technology, chronograph functionality, sapphire crystal, and distinctive Black Series styling, the SSC917 Speedtimer combines Seiko’s sports-timing heritage with modern everyday practicality.
