The new caliber arranges three sub-dials at the 3, 6, and 9 o'clock positions, giving the dial a clean, technical chronograph layout in white-on-blue. A special dual-color silicone strap — blue and white, matched to the dial — ships alongside the standard bracelet, and Seiko's proprietary Smart Switch mechanism lets you swap between them with a single push, no tools required. World limited to 2,000 pieces (800 domestic).
