If it were consistent that would be fine, but I tried calibrating the watch long ago with no luck. Here are some typical readings I got:
At rest: on wrist, 79; actual, 65 (14 high).
Bicycling: on wrist, 88; actual, 70 (18 high).
XC skiing: outside of clothing, 48; actual, 28 (20 high).
Here's what I got taking the silly thing off and letting it sit for 15+ minutes as previously suggested:
Room temp: watch, 70; actual, 64 (8 high).
Outside temp: watch, 55; actual, 45 (10 high).
Sitting all night by bed: watch, 63; actual, 56 (7 high).
Nice watch in many respects but as useful as those tiny keychain thermometers for telling temperature.
