Japanese designer, Ken Okuyama, developed the LX collection with Seiko Watch Corporation, taking Seiko's diving watch design and increasing the angles of the watch's surface to give more light reflection. This model incorporates the Spring Drive movement, a watch movement pioneered by Seiko Watch Corporation engineers. Spring Drive generates power like a conventional mechanical watch - with a mainspring - but combines it with an electronic regulator to provide a superior level of accuracy, without ever requiring battery replacement. High-density Titanium case and bracelet with scratch-resistant coating Zaratsu polishing. Screw-down crown - Unidirectional rotating bezel with black IP treatment - indexes and hands with Lumbrite.
