The Qualiät the clock, ... well, plastic and plastic grip, but still it is not broke, and for swimming, if you do not want to dive deep and the ideal companion for biking. The Casio clock is very robust, even though I have ventured no punches on the clock, lintels etc. could yet cause no harm. Therefore, in certain areas, prefer to wear a cheaper clock and be happy that it is so robust :-)
