The sheer magnitude of this mighty timepiece is superbly executed with surgical-grade solid stainless steel, Swiss automatic movements, and multiple color options of ionic plating. Managing up to 500 meters of water, finished off with a unidirectional rotating bezel, integrated shock resistance, and Invicta’s luminous Tritnite? hands, the Subaqua is the diver’s definitive in negotiating any adventure by sea or by land. Screw Down Crowns: Many Invicta watches are equipped with a screw down crown to help prevent water infiltration. This is most common on our Diver models. In order to adjust the date and/or time on such a watch, you must first unscrew the crown before you can gently pull it out to its first or second click stop position. To do this, simply rotate the crown counterclockwise until it springs open. When you have finished setting the watch, the crown must then be pushed in and screwed back in tightly. Not doing so will cancel the water resistance of the watch and will void all warranties from the manufacturer. Overall, this process should not require a lot of effort or force.
