Got this watch as a gift.  It is an automatic that requires no batteries.  The watch is well made, beautiful to look at, and is accurate for a mechanical watch.  It is a 20 jewel movement.  There is no date window.  The dark blue face and hands really pop.  Do not expect the hands to glow in the dark.  This appears to be a well made watch with detail to workmanship.  I love the stainless watch band with the easy to release catch.  Love that the watch is waterproof.  Waterproof, to me, means that if the watch gets wet then the interior parts will not be affected.  I would not take the watch into a swim pool or other body of water.
