Seiko 5 Sports SBSA098 Automatic Blue Dial Black NATO Strap Japan Exclusive Watch

Seiko 5 Sports SBSA098 combines the iconic Seiko 5 Sports silhouette with a bold Japan-market colorway. Its sunburst navy-blue dial is paired with rose-gold-tone hands and markers, a blue unidirectional bezel, a black hard-coated stainless-steel case, and a black NATO-style nylon strap. Inside, Seiko’s 4R36 automatic movement delivers manual winding, hacking seconds, a day-date display, and approximately 41 hours of power reserve.

Built for everyday wear, the SBSA098 features Hardlex crystal, LumiBrite on the hands and indexes, a screw-down see-through case back, and 100 meters of water resistance. The 42.5 mm case gives the watch a substantial sports presence while the nylon strap keeps it comfortable and versatile.
