Why Does My Tempe Keep Disconnecting From My Watch?

At the start of an activity or when you view the temperature widget, your watch will look for a previously paired tempe™ sensor and will connect it if it is in range and powered on. Once you have concluded your activity or left the temperature widget page for more then 30 seconds, it will disconnect again to conserve battery. 

For steps on pairing sensors to your watch, see your owner's manual.
