The SSK033K1 takes the SKX-shaped GMT case and gives it a cleaner, more versatile look — a white/silver dial under a dual-tone blue-and-black bezel, with a large blue GMT hand for instant readability.

The 42.5mm stainless steel case pairs LumiBrite hands and markers with a magnified date window, all protected by Hardlex crystal. The five-row “beads of rice” bracelet closes with a three-fold, push-button clasp with a secure lock, and a see-through screw-down caseback shows the movement.

Inside is Seiko’s in-house 4R34 automatic GMT caliber — hacking, hand-winding capable, 24 jewels, magnetic resistance to 4,800 A/m, and around 41 hours of power reserve. Water resistance is rated to 100m.
