Forerunner 920XT: WAS $450, NOW $200

Like the Forerunner 735XT, the 920XT is a multi-sport watch that tracks running, swimming and cycling activities. The major difference between the two watches is that the 920XT does not have wrist-based heart rate technology. It does make up for it with the special features listed below:

Unlike the 735XT and the 920XT, the Vivoactive HR is NOT a multi-sport GPS watch. That means that if you were doing a triathlon, transitioning your watch from swim to bike to run requires a little more effort and your recorded time will not be continuous. It also does not include an open water swimming mode.
