I brought the watch because I map pipework of large buildings and need to know where I am when underground. The compass feature works well enough to get you in the right area, but please don't attempt real navigation with it. The tide and temperature features will again get you in the ball park. Draw back for myself is that it is somewhat bulky and the buttons get snagged on clothes, bag straps etc.

I am very disappointed by this product.
First, it is too large, you must have the wrist of the hand of a sumo wrestler.
Secondly, the compass does not work. It shows all directions but not directly north. If the watch is rotated, the pointer does not move at all. Consequently, if the the first time indicates north, after the clock was turned, it indicates another direction as if it is north. The thermometer is greatly influenced by body heat. Consequently, it does not indicate any outdoor temperature and or body temperature. Value indicates by the clock has no practical relevance. I do not recommend this product.
