For me, the perfect watch would be one that:

 Never needs a battery (i.e., solar)
 Goes to sleep when sitting in a drawer to conserve power
 Always has exactly the correct time and date without having to be reset
 Can be read at night using a backlight
 Looks nice enough to wear all the time
 Would be at least reasonably water resistant
 Have dual time zones and chronograph functions
 Have a synthetic sapphire crystal

Except for the last requirement, this watch meets all my criteria. It simply does everything well. In short, if the above matters to you, buy this watch.
