Comments about Tide Indicator Watch:

I bought this for a week-long kayak trip in which it would be valuable to conveniently know the tide situation without having to fiddle with a hand-held GPS, tide tables, or smart-phone. The tide indication on the watch works fine with one caveat. It only graphically shows the rising tide. For the falling tide, the tide graph doesn't give any indication of the progress. This is due to the way the LCD screen is designed. The best you can do for the falling tide is to glance at the screen to realize that you are in a falling tide situation (because nothing in the tide graphic is colored in) and then toggle through the menu to find the time of the next low tide and do a mental calculation to determine the falling tide progress. For the rising tide, you can simply glance at the tide graphic on the screen to see where in the rising tide part of the cycle you are in.

To initially set the tide predictor up, you have to go through the menu to enter the next high or low tide. Then it will predict them going forward. If you are traveling through different costal regions, though, you will need to update the tide information setup because high tide at location A won't be the same as high tide at location B even at the same longitude due to terrain differences.

The watch has the moon phase on the display and nice large digits for the time which is nice. The display is easy to read in bright sunlight and there is a built-in light for night viewing. It is only rated to 50m (splash resistant) so don't go swimming with it. It is a tad large for my wrist so I probably would not wear it as an everyday watch.
