Garmin Forerunner 645 Music. This is a great watch and fitness tracker. If you want to track daily progress with steps, heart rate or even stress level - this is the device. Runners, skiers and bikers can also keep their daily activities and it can be set for reminders and updates for achieving personal best and progress. The face can be customized to reflect the date, time, or fitness data for you to see in a glance. Can be paired with compatible smartphones and/or bluetooth headsets, and can download up to approximately 500 songs. Listen to music while working out. Will set up with wiFi and is GPS capable. There is also an altimeter and compass, along with other applications that can be added from the Garmin App. Very customizable. It's never been used; however, before adding it to my closet I charged the device to check for functioning. I went outside and it connected with GPS and the correct time and date adjusted immediately. Seems to be in excellent working order. My sons have fitness trackers and didn't need this one, so it's up for sale. Comes with charging cord and a quick start guide. Online tutorials and the Garmin app will be helpful to use it to its full potential. This s a 2019 model and is compatible with current Garmin apps. Model 010-01863-22. All functions have not been tested. I am unaware of any faults, malfunctions or imperfections with this device.
