A palindrome is a sequence of letters or numbers that reads the same forward and backward (ex. madam I’m adam).

How the Whatch Works (example at left): Blue numbers indicate hours. These numbers are the first half of a numeric palindrome. (They represent hours.) The second half is not displayed, but must be completed mentally: 08 has the palindrome 08:80. (The “:80” represent minutes.) The red (or green) numbers indicate the minutes that must be added (green) or subtracted (red) to get the time.  {Zero on the bottom would be colored blue.}

 

Time computation: 80 blue with 45 red translates as 80-45 = 35. The time is 08:35
