Since 1965 when Seiko launched its first navigator's watch, it has innovated with new tech, features, and designs. The Seiko Prospex navigator's watch collection is a hit among professional and recreational navigators globally. Over half a century of innovation, Seiko has expanded the limits of sports and navigator's watches. Key features include: a 42mm stainless - steel case, a stainless - steel bracelet, a three - fold clasp with a secure lock and push - button release with an extender, a blue dial, an automatic movement with manual winding ability, an approx. 72 - hour power reserve, a sapphire crystal, LumiBrite on hands, indices, and bezel, 200m water resistance, and style# SPB187.
Using your Seiko Prospex diver watch is easy. Wind it manually if you haven't worn it for a while to get the power reserve going. The watch is water - resistant up to 200m, so it's great for swimming or diving, but don't open the case underwater. For maintenance, keep it clean with a soft, dry cloth. Avoid exposing it to extreme temperatures or magnetic fields. Check the power reserve regularly, and if it's running low, give it a few winds. This watch is built to last, so with proper care, it'll serve you well for a long time.
