Seiko Prospex SRPL15K1 — Automatic Diver's Watch

The Seiko Prospex SRPL15K1 is a compact automatic diver's watch in a committed all-black execution — black case, black bezel, black dial, and black silicone strap throughout. The 41.7mm black stainless steel case with Diver's 200M water resistance and screw-down crown meets the full professional diver's specification, and the all-black aesthetic gives it a purposeful, tool-watch character that pairs naturally with active and casual wear. Powered by the in-house 4R35 automatic calibre with hand-winding capability and a 41-hour power reserve, it is mechanically dependable and practically complete.

Lumibrite on the hands and hour markers ensures readability in low light and at depth, and the Hardlex crystal provides reliable scratch resistance for active daily use. The black silicone strap is comfortable for all-day wear, sits securely on the wrist during water activities, and gives the all-black execution a uniform finish from dial to clasp. At 12.3mm slim and 41.7mm diameter, it is one of the most wearable Diver's 200M automatics in the Prospex lineup at this price point.

Why You'll Love It

The SRPL15K1 is the Seiko Prospex diver for those who want the complete all-black execution at an accessible price point. The 4R35 calibre is one of Seiko's most proven automatic movements, the Diver's 200M rating is the full professional specification, and the all-black case-to-strap execution gives it a visual coherence that the stainless variants in the lineup do not share. At 12.3mm thick and 41.7mm diameter it wears with the compact, easy presence of the best everyday divers — big enough to read clearly, slim enough to move naturally under a cuff. The silicone strap handles water, sweat, and activity without complaint, the Lumibrite ensures readability from dusk to underwater, and the screw-down crown closes the water resistance specification properly.

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. Since 1965, when Seiko created Japan's first diver's watch, the Prospex dive line has stood for underwater precision and reliability. The SRPL15K1 carries that sixty-year legacy forward in a compact, all-black 200M automatic diver built for daily use.
