The typical modern LED usually has hours, minutes, month, date, and nothing else. This one, however, also has seconds, day-of-week, and an alarm. It's very surprising since even the 'name-brand' modern LED's from Diesel, Adidas, and Lucky, which sometimes cost as much as $200 US, don't have these features - and this is a cheap watch from Hong Kong that costs about $15. Very strange.
Each of the four buttons on the watch displays the time on the first press, with each second press displaying a different function depending on which button it is, as follows:
upper left: month and date
lower left: alarm set time
upper right: running seconds
lower right: day of week
