- Perfect size for a runner’s watch
- All the advanced running features that marathoners want
- Intuitive software
- Water resistant down to 50 meters
- VIRB and music playback
- No wrist heart rate monitor
- Not fans of the touchscreen even though it’s a full-color display
- Too expensive
Best pure-play runner’s watch. We just wish it had a built-in wrist heart rate monitor.
We really like the FR630. The size is perfect. It’s comfortable to wear. The display is bright and full color. The software is easy to use. But the touchscreen is not our favorite and it’s probably not the best idea for a runner’s watch. Additionally, there is no built-in heart rate monitor so you always have to pair it with a chest strap HRM. When you do pair it with an external HRM, however, you will get your advanced running dynamics such as ground contact time and vertical oscillation, which hardcore runners seem to really value. These are in addition to the watch by itself estimating your cadence. Beyond being a runner’s watch, the Forerunner 630 is your activity and sleep tracker and does have baseline smart features. It’s not an impulse buy [See on Amazon], but if you want a solid GPS running watch and do not care about the lack of a wrist HRM, it’s a good option.
