SEIKO CHRONOGRAPH SSB347P1 QUARTZ MEN WATCH

Seiko SSB347P1 — Conceptual Chronograph Quartz Watch

The Seiko SSB347P1 is a bold all-black quartz chronograph from the Seiko Discover More range — and the leather strap sibling of the SSB349P1. Where the SSB349P1 pairs the same hard-coated case with a black silicone strap for active and water-ready use, the SSB347P1 fits a cow leather strap to the same specification — bringing a more classic, dressed-down character that transitions more naturally from active sport to everyday and smart-casual wear. The 43.9mm hard-coated stainless steel case, the black tachymeter bezel, and the black dial maintain the visual authority that defines both models; the strap changes the register.

Powered by the 8T63 quartz calibre with ±15 seconds per month precision, the SSB347P1 delivers 60-minute chronograph measurement in 1/5-second increments, a tachymeter scale for speed calculation, a 24-hour hand for secondary time zone reference, and a date display. Lumibrite on the hands and indexes ensures legibility in low light. A screw caseback and 10 bar / 100M water resistance complete the specification. At 43.9mm and 12.9mm slim, it wears with confident wrist presence across a wider range of daily contexts than the silicone variant.

Why You'll Love It

The SSB347P1 is the Seiko Conceptual chronograph for those who want the all-black 8T63 specification in a leather strap format. The hard-coated case and tachymeter bezel give it the same visual authority as the SSB349P1 silicone variant, but the leather strap adds a versatility dimension that silicone cannot match — it works from weekend casual through to smart office settings without looking out of place, and it gives the all-black case a traditional sports watch character that sits naturally across a wide range of daily contexts. The 60-minute 1/5-second chronograph and tachymeter scale deliver the complete motorsport timing function, the Lumibrite ensures the dial is always readable, and the 100M water resistance means the leather strap is the only practical limitation for water use.

SSB347P1 vs SSB349P1 — Leather or Silicone?

Both models share identical specifications — the same 8T63 calibre, 43.9mm hard-coated stainless steel case, 12.9mm slim profile, Hardlex crystal, Lumibrite, fixed tachymeter bezel, 60-minute 1/5-second chronograph, 24-hour hand, date display, screw caseback, and 100M water resistance. The difference is entirely in the strap. The SSB347P1 has a cow leather strap — the more versatile and formally wearable daily choice. The SSB349P1 has a black silicone strap — the more active, water-ready, and sporty choice. Same Conceptual chronograph specification, two different wear registers.

The Seiko Story

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. Since then, Seiko has grown into one of the world's few truly vertically integrated watch manufacturers — designing, developing, and producing its own movements, cases, and crystals in Japan. The SSB347P1 carries that tradition of honest, capable watchmaking forward in a quartz chronograph built for those who want reliable sports timing without unnecessary compromise.
