I had this watch from 2008 this is was my gift from my Mrs. It\’s still working for this day all the triple sensor on the watch works as the day I got them. Even the battery is great if you see them battery is still high, I just leave it near window and It had a hard life. I wear it every where. only thing I changed on this watch was the strap. it was bit rubbish. Casio UK replaced it for me for £40 I send it to them and they send it back with new strap installed and all good after that. here is the picture after 11 years of hard use
