I know the Seiko is a diver and the 104 is not, but has anyone in here had experience with both of these watches? I've been looking for a blue dial/black bezel watch that could be a daily wear for a bit. These are my top two choices so far. Kind of leaning toward the Sinn because I like the countdown bezel, I think it would likely be more accurate, and I have a Seiko that I won't likely get rid of. But the SPB149 is a pretty cool watch as well.
