Official description

Designed for those who treat life as the ultimate adventure, the Seiko Prospex line follows every challenge with technological excellence and style. The dramatic 'black series,' a tribute to the dark of the deepest oceans, is expanded with this exceptional timepiece, available only in a limited edition of 600 pieces, with the serial number marked on each caseback. Appropriate for saturation diving under ISO standards, this high-intensity watch features a one-piece stainless steel case with black ion-coating, black one-way rotating elapsed timing bezel, screwdown crown and durable black silicone strap. The rich black dial, including a red second hand, date calendar, and LumiBrite hands and markers, is topped by a sapphire crystal with anti-reflective coating on the inner surface. The 26-jewel automatic movement beats at a frequency of 28,800 vibrations per hour, with a power reserve of approximately 50 hours, and can be wound manually or automatically. 300m Water Resistant
