Prospex LX

Prospex LX Collection Cermet Limited Edition. 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. 300m Water Resistant.
