Walmart offers the refurbished Garmin Forerunner 210HRM GPS-Enabled Sports Watch with Heart Rate Monitor in Black for $84.88 with free shipping. That's $44 under our mention from over a year ago and the best price we've seen for this watch. (It's also $19 under the best price we could find for a refurb in any color elsewhere.) It features an automatic time zone, up to eight hours of battery life in training mode, ANT+ compatibility, position, speed/pace, and distance and calorie data.
A 1-year warranty applies, although it's unclear who backs it.
