The Fitbit Ionic is Fitbit's first smartwatch. The smartwatches feature useful apps and sports sensors to measure your activities and health. Do you often jump on your road bike or like to go out running? The navigation function will let you easily discover new routes. The Ionic is waterproof, and thanks to the plastic watch strap, it's also suitable for swimming. You can change the dials and straps, so you can match the smartwatches to any outfit or occasion.
