SEIKO SRPH87K1 AUTOMATIC BLUE DIAL MEN WATCH

Seiko SRPH87K1 — Automatic

The Seiko SRPH87K1 is an everyday automatic built around Seiko's dependable mechanical movement — a self-winding watch powered by the motion of your wrist, with a striking blue dial, the reassuring practicality of a date window, and a stop-seconds function for precise time-setting. At 41.2mm in stainless steel with a see-through caseback, it puts honest mechanical watchmaking on display at an accessible price, in a versatile everyday size.

Inside is Seiko's Caliber 4R35 automatic with manual winding and hacking seconds, holding an approximately 41-hour power reserve on 23 jewels — set it down on Friday evening and it's still running Sunday morning. A Hardlex crystal protects the dial, and 10 bar (100m) water resistance covers swimming and daily wear, while the see-through screw caseback lets you watch the automatic movement work.

Key Features

• Caliber 4R35 automatic movement — a self-winding mechanical calibre with manual winding and stop-second (hacking) function for precise time-setting; no battery required.
• Approx. 41-hour power reserve — on 23 jewels, beating at 21,600 vibrations per hour; keeps running through a weekend off the wrist and rewinds through daily wear.
• Blue dial with date display — a rich, versatile dial colour that reads clearly at a glance, with everyday date practicality built in.
• See-through screw caseback — the exhibition back puts the automatic movement and rotor on view, secured with a screw-down seal.
• Hardlex crystal — Seiko's proprietary hardened glass, resistant to everyday knocks and scratches.
• 41.2mm stainless steel case and bracelet — a versatile mid-size profile, 11.8mm thick and 48.5mm lug-to-lug, with a 20mm lug width and a three-fold clasp with push-button release.
• 10 bar (100m) water resistance — rated for swimming and recreational water activity, not diving.

Why You'll Love It

The SRPH87K1 is a first automatic done right — or a dependable everyday mechanical for someone who already knows the appeal. It gives you the things enthusiasts value most in an accessible Seiko: a self-winding movement you can see through the caseback, hacking seconds for setting the time exactly, a practical date, and a versatile blue dial that dresses up or down. At a versatile 41.2mm on a stainless steel bracelet, it wears comfortably from the office to the weekend — reliable Japanese mechanical watchmaking without the premium price.

SRPH87K1 vs SRPH85K1 vs SRPH89K1 — Blue, Silver-White, or Green?

All three are the same watch in different dial colours — identical 4R35 automatic movement, 41.2mm stainless steel case and bracelet, Hardlex crystal, see-through caseback, and 100m water resistance. The difference is the dial. The SRPH87K1 wears a rich blue dial — a bold, versatile everyday look. The SRPH85K1 has a clean silver-white dial — the brightest, most classic and formal-leaning choice. The SRPH89K1 wears a dark green sunray dial — the richest and most distinctive of the three. Same mechanical watch, three distinct characters.

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 4R35 automatic at the heart of the SRPH87K1 carries that tradition of honest, capable mechanical watchmaking forward in an everyday automatic built to be worn and enjoyed.
