Triple Chronograph TRC-100

Three independent Chronographs
Require a bit of manual study to be able to proficiently use them. The three chronographs have color coded buttons (green, red, lightblue) to start them. They can also be started together. It gets a bit more tricky if you time e.g. three runners and then start using split times or lap times. You better practice a couple of times before you promise your children that you would bring your fantastic Casio to their sports day ;-)
