The accuracy of his heart rate monitor is comparable to my portable digital heart rate monitor HB (Omron brand). His thermometer is comparable to my Accurite Weather Monitor and alcohol thermometer. Its compass is also accurate, but always needs calibration. The downside is its readability, poorly readable number due to low contrast and poor backlight. In general I liked the watch, the size of the case is just right for my wrist and the bow of the strap is very comfortable on the wrist.
