I have had two of these watches - the first I inadvertantly took on a deep dive and managed to flood it.  (Note WR 100 does not mean you should take it on dives).

 The second had an issue with the internal battery about a year after I bought it.  Citizen replaced it and had it returend to me within 10 days.  They have very efficient warranty service.

 I am a bit clumsy, so bash it on things all the time - both the band and the watch face do not show wear.

 Overall quite a reliable watch for a much more reasonable price than the big-name brands.
