Seiko 5 Sports SRPK87K1 Automatic – SNXS Re-Edition

The Seiko 5 Sports SRPK87K1 is a modern reinterpretation of a true classic. It takes the iconic SNXS case design , which many Seiko fans have appreciated for decades, and translates it into a contemporary, everyday sports watch. With its compact dimensions, dark blue dial, and stainless steel bracelet, it appears sporty, balanced, and pleasantly understated.

The watch is powered by the tried-and-tested 4R36 automatic movement, known for its robustness and reliability. With a power reserve of approximately 41 hours , a hacking seconds function, and automatic winding, it offers precisely the features one expects from a modern mechanical watch. LumiBrite on the hands and indices ensures excellent legibility in darkness or low-light conditions – a typical feature of the Seiko 5 Sports line.

The transparent case back offers a view of the movement and underscores the watch's mechanical character. Thanks to its 10 bar water resistance, the SRPK87K1 is perfectly equipped for everyday use – from the office to leisure activities. A classic Seiko 5 Sports: functional, honest, and with a clear design language.
