Of Casio, Suunto, Garmin and Apple
These four brands create watches. Casio creates rugged watches with batteries that last for a decade or more, and pair with mobile phones to track walks and more. Suunto and Garmin have fitness/sports trackers that measure activities, whether sailing, climbing, running, walking, cycling, scuba diving or more. Apple in contrast creates fragile, mediocre watches that cost as much as mid to high range watches and yet their battery lasts for one day, if you’re lucky. I even heard that Apple watches with 4g last half a day between charges. Charging a watch twice a day is unacceptable.
