Seiko Prospex Speedtimer SPB515 Black Dial Countdown Watch

The Seiko Prospex Speedtimer SPB515 channels the golden era of motorsport with a contemporary edge.

Its black dial presents a more dramatic interpretation of the same formula that makes the SPB515 exceptional. The hairline-finished surface provides the perfect backdrop for applied indices and that signature orange-tipped seconds hand, creating contrast that serves both style and legibility.

This timepiece features Seiko's innovative inner rotating countdown bezel, a practical complication operated independently via the crown at 4 o'clock. Whether measuring pit stop durations or tracking meeting intervals, the orange-highlighted final 15 minutes ensure you'll never miss a deadline. The 39.5mm stainless steel case, fortified with super-hard coating, achieves what seemed impossible: housing Seiko's workhorse 6R55 caliber in the thinnest 6R-based case ever produced. At just 12mm in height, it slides under a cuff with ease while maintaining 200 meters of water resistance.

The 24-jewel automatic movement beats at 21,600 vibrations per hour, offering manual winding capability and a practical 72-hour power reserve. Curved sapphire crystal with inner anti-reflective coating protects the dial, while LumiBrite hands and markers ensure readability in any lighting condition. The multi-row bracelet flows seamlessly from the case, secured by a tri-fold clasp with push-button release.
