Casio Men's G-Shock Black and Red Multi-Function Sport Watch
Watches that have perpetual calendars will always show the correct date. This is a major advance on ordinary date watches that have to have the date manually corrected every few months. The perpetual calendar watch has to be set with the year, month and date. Once this is set, either at the factory or by yourself, the date will not need adjusting. Some watches will show all of this information particularly if they are digital watches. The traditional analogue dial watch will show some of this depending on the complexity of the dial. Another alternative to the perpetual calendar watch is to have either a radio controlled or GPS Satellite controlled watch. These are the ultra modern versions available in many brands.
