The compass works great. There is a setting to adjust for declination (which you can find on online) so you can get true north or you can opt for magnetic north. The compass shows heading and north for about 5-6 seconds, then the compass turns itself off. I don't know if that is something that saves power or improves accuracy. I presume it was designed that way. Temperature sensors on watches are always a joke since you have to take the watch off and let it sit for a few minutes or else you get the temperature of your wrist interfering with the reading. Don't buy it if you want a thermometer, just buy a separate thermometer - a small one you can put on the zipper of your coat.

The core watch features work well, alarm, timer, stopwatch. I especially like the layout of the date with the month/ day/ day of week noted in the three letter abbreviation (as opposed to the two letter abbreviation used by timex). The light only last for two seconds even if you keep the button pressed. I don't like that. I wish the light stayed on as long as the button was pressed and I wish the time the light stayed on was adjustable.
