Inspired by the reflection of the sea on a moonlit night

Designed for those who treat life as the ultimate adventure, the Seiko Prospex line follows every challenge with technological excellence and style. Available only in a limited edition of 200 pieces, with the serial number engraved on each caseback, this saturation diver, meeting ISO standards for scuba diving to depths of up to 300 meters, features a bezel crafted of Cermet, a proprietary Seiko material offering the hardness of ceramic with the finish, appearance and shine of metal. Eight times harder than steel, Cermet provides enhanced shock protection. Powered by a Seiko Spring Drive movement, this precision watch combines a 30-jewel mechanically driven movement with a quartz regulator for accuracy to +/- 1 second per day, +/- 15 seconds per month. With a power reserve of approximately 72 hours, the movement can be wound manually or automatically. Crafted of light and durable titanium with a black super-hard coating for nearly doubled hardness, this superbly reliable watch features a screwdown caseback and crown, as well as a black silicone strap. The dark gray dial, topped by a curved sapphire crystal with anti-reflective coating on its inner surface, includes a power reserve indicator, date calendar, and LumiBrite hands and markers, and is framed by a unidirectional Cermet bezel in a dark platinum shade to suggest the sea surface in moonlight. Limited edition of 200 pieces
