Did you know that 10:08 is the time used in most watch advertisements?  (Well, the time varies between 10:08 to 10:10.) 

Here are several reasons why watch companies use this time:

• The form of the hands has a positive effect on the view: the short hand pointing at 10 o'clock and the long hand pointing at 8 minutes is reminiscent of a check mark, which commonly means "ok" or "fine."  Some observers further identify this appearance with a smiling face.
• The position of the hands does not obscure the date on watches with a date-function at 3 o'clock or any other functions at 9 or 3 o'clock.
• The position of the hands does not obscure the company logo, which is often printed under 12 o'clock.
• The hands are nearly symmetrically balanced ont eh face of the dial at 10:08.  The minute hand is 48 degrees right of vertical, while the hour hand is 56 degrees left of vertical.  Exact symmetry would be achieved at 120/13 minutes past 10:00, approximately 10:08:13.8.  Other symmetrical times would not meet the needs above.
• At 10 o'clock in the morning, the day is young.  There is still time to accomplish many things.
• 10 o'clock is the time at which people typically wake up if they are able to sleep in.  10:08 is thus associated with weekend, leisure and relaxation.
