I chose this particular watch because I wanted a smaller sized face and band ( I am a man).  It is quite attractive and has kept accurate time over the month I have owned it.  The unidirectional bezel (it only turns counter clock-wise) was quite stiff at first, but has loosened nicely over time.  I have not taken it into the water, though I do not doubt its worth as a dive watch.
  Regarding the band:  Yes, it will probably need to be adjusted to your wrist.  A local jeweler did this for me in a few minutes for $7.  Unless you really want to mess with it, I recommend doing likewise.
