The Seiko 5 Sports GMT SSK045K1 is a special edition GMT model within the expanded Seiko 5 Sports GMT series. This watch is inspired by vintage motorsport heritage and the classic “velocity blue” color palette, blending sport styling with practical dual-time functionality.

Powered by the Seiko Caliber 4R34 automatic movement, this model delivers reliable mechanical performance with manual winding capability, hacking seconds, and a GMT (dual time zone) function. The movement provides an approximate 41 hours of power reserve.

The watch features a 42.5 mm stainless steel case with a Hardlex crystal protecting a vibrant blue dial. A bi-colour GMT bezel enhances the dual-time functionality and adds visual contrast, while LumiBrite-coated hands and indices ensure strong legibility in various lighting conditions.

Rated to 100 m / 10 bar water resistance, the SSK045K1 is suitable for everyday wear and light aquatic activities. The five-row stainless steel bracelet with a secure three-fold clasp completes the look, and a screw-down caseback with exhibition window showcases the movement inside.

This model appeals to enthusiasts looking for both GMT functionality and a distinctive, motorsport-inspired design.
