SEIKO PROSPEX SSC917P1 BLACK SERIES SOLAR CHRONOGRAPH MEN WATCH

Seiko Prospex SSC917P1 — The Black Series 'Night Speedtimer' Solar Chronograph

The Seiko Prospex SSC917P1 is The Black Series Night Speedtimer — an all-black hard-coated Speedtimer Solar Chronograph built around the concept of night mission readability. Every element is rendered in black: the hard-coated stainless case, the bracelet, and the dial. Against that total blackout, the newly developed green Lumibrite Pro on the hands and indexes is the design statement — green is the colour that stands out best in darkness, and the Lumibrite Pro formulation is designed to maintain the same intense green in both light and dark conditions, creating the impression of looking through a night vision scope. A solar chronograph that functions as a proper tool in the dark.

Powered by the V192 solar calibre, it never needs a battery replacement and charges from any light source. The V192 delivers 60-minute chronograph measurement in 1/5-second increments with split-time capability, a tachymetre scale for speed calculation, a power reserve indicator (activated at the touch of a button), and a 24-hour hand for secondary time zone reference. The curved sapphire crystal with anti-reflective coating on the inner surface ensures clarity in all light conditions, and the screw caseback with three-fold clasp and push-button release completes a fully resolved professional specification at 39mm and 13.3mm slim.

Why You'll Love It

The SSC917P1 is the Seiko Prospex Speedtimer Solar for those who want the complete all-black execution — not just a dark dial, but a fully hard-coated case and bracelet that absorbs light rather than reflecting it. The Night Speedtimer concept is coherent from the ground up: the black execution removes every reflective surface, and the green Lumibrite Pro ensures the hands and indexes read with exceptional clarity in exactly the conditions where black cases are usually hardest to read. At 39mm it is the most compact and wearable solar chronograph in the current Speedtimer lineup, and the V192 platform means no battery concern for a decade of typical use. An all-black solar chronograph with a night-vision concept that is as functional as it is striking.

SSC917P1 vs SSC933P1 — All-Black or Colour Dial?

Both models use the V192 solar calibre in the compact 39mm Speedtimer case with identical chronograph specification — 60-minute 1/5-second split time, tachymetre scale, 24-hour hand, power reserve indicator, curved sapphire crystal, and 100M water resistance. The SSC917P1 is the all-black Black Series execution with green Lumibrite Pro — the night-vision concept in a stealth case and bracelet. The SSC933P1 has a green dial on a silver stainless bracelet — the more conventionally styled and versatile everyday choice. Same compact solar Speedtimer specification, two completely different characters.

The Seiko Prospex Story

Prospex is a combination of the words "Professional" and "Specifications." Seiko Prospex timepieces are designed to be practical, reliable, and durable — built to meet the high standards required in extreme environments for sports lovers and adventure seekers alike. The story begins in 1881, when Kintaro Hattori founded a clock and watch shop in Ginza, Tokyo — the business that would become the Seiko of today. The Speedtimer name has been part of Seiko's motorsport heritage since 1969. The SSC917P1 carries that legacy forward in the most visually committed Black Series expression of the compact solar Speedtimer.
