First one I received had a bad seal in it. So after being in the pool it had condensation built up under the cover and stopped working. I filled out a return form and notified Amazon of the issue on the return form. Received my replacement and have not had an issue with the seal on this one. The pin that holds the watch to the band however came out very easily. So now I have to get a replacement pin for it. The watch however is still ticking and looks great.
