The Seiko 5 Sports GMT brings genuine GMT functionality to Seiko's accessible 5 Sports line for the first time, built around the in-house 4R34 caliber — a caller-GMT movement with an independently adjustable 24-hour hand paired to a bidirectional rotating bezel for tracking a second timezone at a glance. At 42.5mm with a black hard-coated stainless steel case, it wears with clear SKX-diver styling.

The 4R34 offers hand-winding and hacking seconds alongside its 41-hour power reserve, and a screw-down see-through caseback shows off the automatic movement in motion — a detail rarely offered at this price point.
