I gave this watch a four becuase the instruction guide that came with the watch is completely useless.  They waste pages in the guide on how the Navy Seals love this watch.  I would also like to love this watch if I knew how to use it!  All I could figure out from the instructions is how to set the proper current date and time.  I have no idea what the other three dials can do.  I have heard it has an alarm, chronograph, etc. but I have no idea how to work the other features.  Swiss made, but some marketing idiot in the US wrote the terrible instruction guide.  The Swiss would never have left such a poor guide on such a great watch.
