Before the super high-tech 935 and even the equally impressive 735, Garmin’s warhorse was the tried and true Forerunner 620, one of the true pioneers in high-tech runner’s watches. It measures your training based on VO2 max, or oxygen-intake potential and helps to improve your times by providing reasonable goals based on hard data. The 620 also provides optimal recovery times, telling just how long you should wait before pushing your limits again, and the syncing to Garmin Connect lets you live-track and share your runs via social media.
Right now, you can pick up Garmin’s Forerunner 620 running watch for just $127 on eBay. Yes, you'll have to accept the orange and white color scheme — if you're not man enough to pull it off, feel free to cough up $200 more for the blue and black Forerunner 620 at Garmin.com.
