^ Then 533 it is!
More seriously, going with your heart is the only way to go, as you know I've said before. As soon as one tries to convince oneself that another piece makes more "sense", they get away from what they love and inevitably end up flipping or feeling unsatidfied. It kind of sounds too simple, but you have to go with what makes you smile. And even if you ultimately stick to the 689 and 359, you'll have two absolutely killer watches that make you smile. Happy for you.
