Seiko 5 Sports SRPJ45K SKX "Skeleton Style" Automatic Watch

Inspired by Seiko’s Iconic Time Sonar Design

The Seiko 5 Sports SRPJ45K takes inspiration from the iconic ‘Time Sonar’ watch, featuring a translucent dial that reveals the rotating day-date discs beneath. This eye-catching design is complemented by a striking red-orange second hand, echoing the aesthetics of the original 1970s model.

Built in the signature SKX case shape, this timepiece reflects the evolution of Seiko 5 Sports, a collection renowned for over 50 years of reliability, durability, and performance. The SRPJ45K stays true to the five essential Seiko 5 features: automatic movement, day-date display, water resistance, a recessed crown, and a durable case and bracelet.

Blending vintage inspiration with modern functionality, this watch is a must-have for collectors and everyday wearers alike.
