I am not a watch person myself though I do wear a Garmin Instinct 2 Solar that I bought last year for some of the activity tracking functionality. It is the first thing for a wrist that I have worn in more than 40 years so I am still getting accustomed to the feel of something on my arm. I may ultimately give it away after getting enough data to understand where I am in my personal fitness at my age (>60). If I were a watch person I would definitely be a G-Shock person. I bought one for a brother more than 20 years ago when he joined the Army and needed a durable watch. His model charges by solar and syncs to local time via radio I think. No matter where he has traveled he always had the correct time. He told me that the watch has never had a problem and that he wouldn't consider "upgrading" to a smart watch which would tie him to a charger. Casio makes excellent watches and their entry into the smart watch domain should be interesting. I bought the Garmin because of the battery life, feature set, and reliability and because I have used Garmin GPS devices and know them to be excellent devices. Casio has a similar reputation for quality and so they should be on anyone's short list of devices to consider.
