Reliable and accurate on land and in water. This is the goal of the Seiko Velatura series of yachting and nautical watches. While women's models are available in silver and gold and are powered by a quartz movement, men's sea-colored models include a kinetic-powered watch. Therefore, the movement of your hand will keep them running. The reserve of its operation is up to 6 months. The watch glass is sapphire and the water resistance corresponds to its usability for water sports.
