I bought the clock as a sports and leisure watch. It was important, especially the stopwatch to run and an illumination.
When I ordered the clock, I had strong concerns because the clock is only splash-proof and is not waterproof. This was me because of the price but also somehow do not care as much more expensive sports watches were also leaking sometime soon and scratched.
I use the clock for three years now almost every day. I'm going to run with it, climbing, swimming in the indoor pool and in the sea. Even in the sauna I had the clock while already. I have also repeatedly pressed the buttons under water and the clock still works properly. Only the case has already had not even resisted some scratches from the rocks, but not too disruptive and any other clock.
If the clock one day give up the ghost, I will certainly buy me back a Casio.
