Used Garmin Forerunner 35. I have had it about a year, but I’m upgrading, so it works perfectly and never had any issues. Compatible with Garmin Connect app. It offers smartphone notifications, tracks steps and sleep, and can be set to capture workouts including cardio, biking, and running. A great simple fitness watch. Generally retails for around $100. Product specs are here on the Garmin site: https://buy.garmin.com/en-US/US/p/552962/pn/010-01689-00
