Tag Heuer, Breitling, Rolex, Timex... they all compete against each other to position their brand name at the very top but even they agree upon one common ground! All the watch manufacturers set the time to 10:10 (10:09 in some cases) for advertisement purposes. But do you know the reason behind this phenomenon? Apparently, the 10:10 time gives the appearance of a "smiley" which strikes a chord with the people Earlier, watch manufacturers used 8:20 as the time, for advertisements. But they realized that it looked more like a frown, and that would dissuade people from buying it. 10:10 symbolises happiness!

This also explains why the seconds' hand is usually set to '35' so that the aesthetic beauty, arising out of the angles made, stays intact.

Symmetry reasons

10:10 assures vertical symmetry in the face of the clock. But the same could be achieved with the time being set to 8:20 or 9:45, then why do manufacturers prefer 10:10?
