What is smart ?.
Having enough of going to the jewelry shop to have the batteries replaced, not wanting to buy for $30,- stuff on Ebay to do it myself, my battery operated quarz watches are like a dead pile of junk in a box, and i bought the smartest watch ever seen: Seiko 5 automatic for some $ 140,-. It is < 1 min. off per month, always runs, tells the time in darkness without pushing buttons and looks great.
Beautiful piece of engineering.
