A day-date watch is another variation that combines the benefits of the day-of-the-week display with the simplicity of showing the date. A small window on the dial at the 3 o'clock or 12 o'clock position shows the day and date. This feature is a true marriage of functionality and style, making it easy to discern the information applicable to the present day.
Most day-date watches also automatically advance the day and date based on the number of days elapsed. This dual functionality is extremely popular on dress and sports watches. It adds extra utility for those who like to have all essential calendar information on their wrist.
