The Nike+ SportWatch GPS is designed to be simple and intuitive with only three buttons and a Tap Screen for navigation.  The watch works with GPS and an optional Nike+ shoe sensor to record distance, pace, elapsed time, and estimates the calories burned while running. With an optional heart rate monitor, the watch will also record your heart rate.  Upon completion of a workout, the watch can be connected to a computer USB port to upload runs to nikeplus.com, where your runs are logged.  You can see graphs of your run and where you went on a map.

The controls on the watch are very simple... two scroll buttons and a Select button to make choices.  During a run, the scroll buttons can be used to toggle the display through your current distance, pace, elapsed time, calories or time of day.  You can also tap the screen to mark laps or turn on the backlight.

After downloading and installing free Nike+ Connect software on your computer, the watch can be plugged into a USB port to set it up, transfer run data and recharge the watch battery.  The USB connector is built into the watch strap.  In photos the connector looks a bit fragile so it will be interesting to see how reliable it is.  Battery life is reported to be 40 days running as a watch and 9 hours when running GPS continuously.

The optional Nike+ shoe sensor will work with the watch to continuously track run information when a GPS signal is weak, or when running indoors.  To start a run before a GPS signal is found, you can use the quickstart feature, which uses the Nike+ sensor (in your shoe) to track run information until your watch locates a GPS signal.

A setup option will allow you to change your "laps" preference from "off" to "auto" or "manual." "Manual" will mark a lap whenever you tap the screen.  Another setup option will allow you to program intervals.  When turned on, you will see the word "run" on the main screen as run time counts down, thenyou're your "interval" or rest time, count down.  The "Run" and "Rest" times will switch back and forth until you've reached your goal.  Note: Laps and Intervals can't be used at the same time.
