I am pleased with the capabilities of this watch.  Accuracy of the Temperature is very good but the watch must be removed from your wrist for temperature of your surroundings. The Temperature response is slow.  The compass is accurate and can be set up to include variation correction for True readings.  I find the Tide readings very good and matching the information from my Tide Clock.  The tide feature is most important to me as I live in the Northeast Tidal area with tides of nine feet ot more and walk on the beaches daily and opperate marine vessels.  The compass is interesting and would be of greater use on land navigation as boats have many compasses available. The temperature is great to check in the morning before I place the watch on my wrist.  Also very important is the time keeping capability, which I find excellent.  I do like the analogue display of the compass better than the digital display I have on another watch.  I do agree with others that the Watch Band will have to be replaced soon.  Due to the size and weight of the watch, it has to be secured snugly and removing it requires sharp bending of the band to release it from the clasp that holds it.  The powered indiglow works well but viewing the Glow from the radiation dots and hands is not effective very long after it is removed from the light.  I find this watch a good value.
