on 21 sept.  me and the dog went through our training.  this incompassed water--lots of it.  we were in the river for over 7 hrs.  this watch got drowned and beat'in up.  literally almost the whole time was under water and hitting and banging on solid items.  it held up great, kept accurate time and with the aluminated face it was easy to see in the dark.  the large even #'s was a big help.  the only thing i would do is change the band to a more comfortable nylon band to prevent chafing and rubbing the arm a little raw from constant movement.  the rubber band held up great but not my fortay for a band.  great watch for water use.
  the only reason for the 4 star was for the band.  for the watch only it is a 5
