Well some prefer the look of a no-date. Cleaner also Ive got to admit. But I work in the office and knowing the date is really really useful. Also, just the date function provides a nice useful complication and some watches like the Hamilton Khaki King actually benefits from the day-date look at the 12 o'clock position. However, same cannot be said for the Rolex Sub or DJ as a cleaner look and the watch looks somewhat, more refined.
