The bones of their software are over 20 years old at this point, back to the Forerunner 101 which came out in 2003, predating modern smartphones. You had to plug them into a COM port to download your runs. I have Garmin watches from this time period that still work, but I can't figure out how to get any data from them. They're also issued in some military circles where they're not allowed to connect to a smartphone, and the lack of a microphone is a plus.
