This is a "updated" version of the one I now have. This update includes a hack feature and the crown sets day date and time thus there is no second button to reset the day. That makes it one less place to have a leak when you forget to screw it down. Well made as I have come to expect from this maker. I also like the metallic blue color of the face and a secure band that is "shrinkable" to fit my wrist. Another new feature is you can manually wind it also so you may not need a auto-winder. Maybe I should buy two!
