I changed the battery in my "Speed" today and was wearing it when the time came to give my little girl her bath. Halfway through the bath she saw my watch and told me to take it off and give it to her.
She immediately threw it across the tub where it hit the porcelain coated steel with a much more voluminous thud then other Gs. She then took the watch and banged it on the bottom of the tub three or four times and then took it out of the water and started hitting it against the back wall and dragging it from side to side.
Needless to say it is still functioning flawlessly but I decided to take the watch away from her and let her play with an old Pathfinder Fishing watch I have. She really liked it when I strapped it to her wrist and showed her how to turn on the lume!
