I honestly use a watch as jewelry, so I don't care about accuracy, and buy invictas, androids, and the like. 
 
Think of it as vw vs honda.  Invicta is VW, and Seiko is Honda.  I prefer VW and Invicta, because I know it's a cheap watch, so just want it to serve the purpose of amusing me.  I see the value of honda tho, and so seiko is a fine choice.  I recommend seiko 5s all the time.  I think generally speaking the difference between a $50 watch and a $200 watch tho is going to either be style, or swiss bragging rights tho.
