SHARK CLASSIC ABC XL

This watch is well constructed and very comfortable but lacks in functionality. Obviously there can't be an expectation that all features of the watch are going to be highly accurate due to the relationship between barometric pressure, temperature and altitude. Any of these variables will affect the accuracy of the other. The only real complaint that I have is the temp sensor is not very accurate. To get a true reading (closer to accurate anyway) the watch has to be off of your wrist. Not too much of a surprise considering the heat from your body will affect the accuracy but I don't usually carry my watch around off my wrist, I can use my cell phone for that. Regardless, the watch suits my needs. I purchased it mainly for the chrono and compass and both work just fine.
