SEIKO PROSPEX SSC913P1 SPEEDTIMER SOLAR CHRONOGRAPH MEN WATCH

Seiko Prospex SSC913P1 — Speedtimer Solar Chronograph

The Seiko Prospex SSC913P1 Speedtimer is the blue dial variant in the 41.4mm Go Large Speedtimer Solar Chronograph format — the same case size as the SSC915P1 black dial sibling, with the same V192 solar calibre and identical specification, distinguished entirely by the blue dial. The 41.4mm case is noticeably larger and more wrist-commanding than the compact 39mm Speedtimer Solar models, and the blue dial against the silver stainless steel case gives it the most classically sport-watch-coded colourway in the 41.4mm format. 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 on the dial, and a 24-hour hand for secondary time zone reference. Lumibrite on the hands and hour markers ensures legibility in low light. The curved sapphire crystal and silver stainless steel bracelet complete a specification that is precise, practical, and well resolved at the 41.4mm format.

Why You'll Love It

The SSC913P1 is the 41.4mm Speedtimer Solar for those who want the blue dial — and in a solar chronograph at this size and specification level, blue is the most natural, most legible, and most classically motorsport-coded choice. The 41.4mm case wears with a more substantial wrist presence than the compact 39mm format, the V192 solar platform means no battery concern for a decade of typical use, and the tachymetre scale and 1/5-second split-time capability mean it functions as a proper sports timing instrument. The curved sapphire crystal keeps the blue dial pristine through daily wear, and the silver stainless bracelet pairs naturally with the dial for a clean, confident everyday sport watch.

SSC913P1 vs SSC915P1 — Blue or Black Dial?

Both models are 41.4mm Go Large Speedtimer Solar Chronographs with identical specifications — the same V192 solar calibre, 41.4mm case, 13.0mm depth, 100M water resistance, curved sapphire crystal, pull-out crown, tachymetre scale, split-time chronograph, 24-hour hand, power reserve indicator, Lumibrite, date display, and silver stainless steel bracelet. The difference is entirely in the dial colour. The SSC913P1 has a blue dial — the most classically diver and sports-coded choice. The SSC915P1 has a black dial — bolder, more dramatic, and the more tool-watch-coded of the two. Same 41.4mm Go Large Speedtimer Solar specification, two completely different visual 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 SSC913P1 carries that legacy forward in the most naturally sport-coded expression of the 41.4mm solar Speedtimer.
