There's a lot to like in the {{Garmin 620}}; it's smaller than many [[Best Running Watch| comparable watches]] and its interface is nice to use. How well the 620 will suit you will depend a long on your needs, so for a simple evaluation of a GPS watch, I look at how well it can answer some basic questions:
* '''How far did I run?''' This is the most basic question, and the 620 has somewhat reasonable, but not great GPS accuracy, so its estimate of how far you've run needs to be treated with a little caution.
* '''What's my cadence? '''[[Cadence]]''' '''is one of the most critical and often overlooked aspects of running. If you get your Cadence right, many other things naturally fall into place. Not only does the 620 get [[Cadence]] from a [[Footpod]], it will also get it from the Garmin Run Heart Rate monitor. There is also support for Cadence from the internal accelerometer, though I find that's not as accurate. The Cadence alerts are especially useful for keeping you on track.
The 620 is not a good choice for ultrarunners, as its battery life is too short. See [[Best Running Watch#Watches for Ultrarunning| Watches for Ultrarunning]] for more details.

* With the updated firmware, the GPS accuracy is reasonable. It's not as good as the [[Polar V800]] or some of the other watches, but it's okay for most usage.
* '''Graphs'''. Instead of simply displaying a numeric value for things like heart rate, some watches will display a graph of the value over time, giving you a sense of how things are progressing.
* '''Web Configuration'''. Some watches allow you to setup the configuration via a web site, and then download your changes. This is vastly easier than fiddling with the watch.
