We really love our Suunto 5 GPS watch. It's very lightweight, compact, and comfortable. Being fully waterproof with multisport-tracking, it can be used for almost any activity. With built-in GPS, 24-7 heart rate tracking, and full integrations with fitness apps like Strava, it's one of the most functional watches on the market. We also love that it has physical buttons - not just touch screen - making it easier to access while exercising.
