This is probably the best performing atomic watch I have ever owned.  Easily picks up the signal every night with no problem.  But, it is the first watch I have found where I could not change the band.  I prefer expansion bands and have always been able to change the band on a watch but not with this one.  Easy enough to remove the band but it will only accept a like band so you are stuck with it.  If it breaks you will be without a watch unless you can order a band from Casio.  I will be looking for a different brand from now on.  You can do better Casio.
