Garmin Forerunner 405 CX
It's no surprise that one of the biggest names in GPS is also a top name in GPS sports watches. The Forerunner series (Forerunner 50, 205, 305, 310 XT, 405, 405 CX) is designed primarily for running and cross training. The 405 CX monitors time, distance, pace and other workout indicators and sends the data wirelessly to your computer where you can analyze it later and adjust your training regimen as needed. You can then go out and try to beat your previous marks. The 405 CX also includes a heart monitor. The watch is compatible with cycling as well, with the purchase of a cadence sensor that tracks your wheel movement. A foot pod can convert the watch into an indoor training tool, where GPS isn't available to provide tracking data. Other watches in the Forerunner series include varied features and are aimed at running, biking and multi-sport applications.
Suunto X10
The Suunto X10 is more of an outdoor sports and adventure watch. This watch is essentially a wrist-top GPS navigation unit that is designed for navigating through the wilderness. The watch includes other staple functions of outdoor sports watches such as altimeter, barometer and compass. The X10 plugs into your computer so that after that epic day in the bush, you can chart your journey using Suunto Trek Manager and Google Earth. Add up to 500 waypoints to more accurately navigate and use Suunto's Trek Manager software to help you plan your trip.
Timex Ironman Bodylink System
The Timex cheats a little bit in that it requires a separate GPS unit, which straps to your other wrist or upper arm. The GPS unit communicates with the watch to provide the distance traveled, speed and elevation. The watch is designed for a variety of athletes including swimmers, bikers, walkers and runners. A heart monitor is included.
