I have upgraded my Garmin watch to the Forerunner 265 so I no longer need the Forerunner 645.
The watch was first released by Garmin in 2018, I have had the watch for about 2 year, bought it new from Amazon in December of 2020 for $414.00
I am looking to get $180, extra watch band included, full printed manual as well.
Note: not the Music version so no internal storage of music files.
