I love this watch.  It is so nice to have the functions this watch brings to the table.  I watched alot of videos before buying this watch and like any watch it is operated and sometimes the operator is the problem.  Temperature gauge  will show your body temperature to within 10 degrees if your wearing it.  So if you want the outside temperature let the air wear it for a few minutes not your wrist.  The compass is quite accurate when on the wrist but even more accurate if laid flat like a map.  If you need perfect north to head north then get a guide.  I love the tide feature being from the coast though you may need to callibrate this to your regional tide times.  Time and date are fairly standard.  The hour and minute hands will glow for quite a while after being in light but I have not tested the time for that.  The indiglo is the true indiglo.  I use it to find my key hole for the door at night.  I did not like the band but that is an easy fix.  It is well made and very flexible considering its strength.  I would recommend this watch.
