This Is Why 10:10 Is The Default Setting On Watches

Have you ever wondered why clocks, watches, and timepieces are almost always set to 10:10 before you set them to the correct time? Many believe that this is done in a way to memorialize Abraham Lincoln/John F. Kennedy/Martin Luther King Jr. since this was the time at which they were shot or died.

However, that is not true. Lincoln was shot at 10:15 pm and passed away the next morning at 7:22 am. On the other hand, JFK was shot at 12:30 pm CST and was declared dead at 1 pm while MLK was shot at 6:01 pm and declared dead almost an hour later. Another theory that gets thrown a lot is that 10:10 was the time when the atomic bomb was dropped on either Nagasaki or Hiroshima, and clocks are set to 10:10 in memory of the lives lost that day. In reality, however, the Fat Man bomb was dropped on Nagasaki at 11:02 am local time, and the Little Boy was dropped on Hiroshima at 8:15 am local time.

So, what is the real reason for this setting? As it turns out, it is because of the aesthetics. The 10:10 position imparts a number of benefits including the following;

As per the people at Timex, the standard-setting used to be 8:20, but that made a face look like as if it was frowning. In order to make the products look ‘happier,’ the setting was flipped into a smile! Share this with your friends and family members so that they can also learn why the watches are set to 10:10.
