My kids gave this watch about two years ago as a Father's Day gift.  I have worn it everyday at work and never had any problems with it.  I love that it sets itself and runs on the sun.  But my favorite feature is at night or in the dark when I bring my wrist up to look at my watch, it automatically turns on the back-lit display making the time easy to see.  Great feature.  the watch is tough too. I've dropped it numerous times with no problems and no scratches on the watch face.  Great watch!
