SEIKO MENS SPORTS 100M SRPL87K1

Description

The Seiko 5 Sports SRPL87K1 is a tough, dependable watch with a sporty edge that’s built to keep up with your day. It runs on Seiko’s 4R36 automatic movement, which means it winds itself as you wear it, and gives you about 41 hours of power reserve.

With 24 jewels inside, it keeps time smoothly and includes practical features like a day/date display and stop-second function. The 42.5mm stainless steel case has a solid feel, while the curved Hardlex crystal and LumiBrite on the hands and indexes make it easy to read—even in the dark.

The silicone strap adds comfort and flexibility, perfect for active lifestyles. It’s water-resistant up to 10 bar and protected against magnetic fields, with a unidirectional rotating bezel and a see-through screw case back that show off its mechanical charm. Lightweight yet rugged, it’s a watch that’s ready for whatever comes your way.
