Beach Camera via Walmart offers the refurbished Garmin Forerunner 620 Watch in Blue/Black, model no. 010-n1128-00, for $129.99 with free shipping. That's tied with our mention of a refurb from September and $220 under the lowest total price we could find for a new unit. It features a touchscreen, water resistance to 165 feet, and tracks pace, distance, heart rate via HRM-Run chest sensor (not included), recovery time, and calorie consumption.
Note: A 1-year warranty applies, although it's unclear who supports it.
