Seiko 5 Sports GMT SSK003K1 – 42.5 mm

The Seiko 5 Sports GMT SSK003K1 expands the popular SKX line with a practical second time zone. The two-tone 24-hour bezel in black and dark blue – often called "Batman" – allows for a clear distinction between day and night. The dark blue sunray dial adds extra depth to the watch, providing a striking, modern look.

The watch is powered by the reliable Seiko manufacture caliber 4R34 with a 41-hour power reserve. Thanks to 10-bar water resistance, Hardlex glass, and a transparent case back, the SSK003K1 is both robust and a real eye-catcher for lovers of mechanical movements.
