THERMOMETER
When worn on wrist, thermometer reading is affected by

and TEMP push buttons move hand clockwise and counter-
clockwise, respectively. Push crown in when done.

or bridges, or objects that give off electromagnetic
radiation, such as televisions or computers, which
could affect the magnetic field around the watch. If the
compass is calibrated near such objects, it will only
