Which is more accurate movement: Citizen's Eco-Drive or Seiko's Spring Drive?

Answer 1

I have both
the moon faced Seiko

and the
citizen square ladies bracelet
and the guys rectangle

the Seiko is more expensive. I love my Seiko's this is my favorite the price is more than my two citizens put together. I like big watches on my tiny wist.

the Seiko will last years, the finish will stay nicer and they also have a sapphire Crystal.

the citizen is great just be in the sun, stays wound up with just a little light
