Question

Why have all the clock and watch companies have 10 past 10 timed in their prit advertisement?

Answer 1

Because it gives the watch a "smilie" face. People like smilie faces

Answer 2

My understanding is that Timex patented that view for their advertizing many years ago, but through the courts, could not uphold ownership.  It is the most desired (holding)face of the watch or clock to view.

Answer 3

Its a conspiracy.
