The watch looks better than the pictures you see here. The blue highlighting on the case is darker and more subtle. The black part of the case has tiny embedded metal flakes and a luster that makes it look more like ion-plated metal than plastic. The backlight lights up the entire face with a soft orange light that has great contrast and won't ruin your night vision. The case measures 43 mm, but the cutouts for the pushers, and the bezel styling, make it look smaller. It doesn't have the bulky, overwhelming look of the G-Shocks and the low weight means it rides lightly on your wrist.
The tide function is improved compared to older Casio tide watches. Older models required you to enter the "lunitidal interval" for your location if you want an accurate tide readout. This watch only needs the time of the first high tide of the day, then it calculates the lunitidal interval and stores it internally for all subsequent calculations- it's a one-time setup. Also, unlike older Casios, this watch displays the relative height of the tide, indicating higher tides near the new and full moons. Note that the tidal model used by this watch is fairly simple and its accuracy depends on how complex the tides are at your location. It is more accurate for the east coast of the US, and less accurate for some locations on the west and gulf coasts. Check the tide graphs on tidesonline.noaa.gov and compare them to what the watch is telling you before relying on it.
Other features I like are: a stopwatch that measures a full 24 hours, dual time display that shows foreign and home city simultaneously, five alarms (a little louder than usual), and a 24 hour countdown timer.Read more ›
I use this watch when I snorkel/freedive and it works great. I chose the Tough Solar as there is no need for a battery replacement which causes the seals to leak after opening the back and reseating.
Setting the Tide was a bit tricky as my city was not on the list. I chose Santiago, Chile which has a code of (SCL) and is GMT-4 which is my
time zone. I don't have DST so I turned this off. I checked on the internet for tide tables for my country and I entered the next high tide in the settings. Voila the tide and moon information is quite accurate and very handy.
Update: I have had this watch for more than 2 years and its still going strong. I am in the sea at least once a week and this watch takes a good beating. Sometimes the currents push me against hard rocks and the watch takes a good hit. It works really good.
The manual however is written in such a tiny font that it is difficult to read. I went to the Casio site and downloaded the pdf manual. I can only read it on the computer because when you print it it comes out really tiny. If you increase the magnification of the pages, it prints with parts missing.
I am very happy as I use this Casio Tough Solar as an inexpensive diving watch. It has loads of functions which I am yet to read up on and is built pretty solid and is quite good looking. This watch might last 20 years for all I know, the only weak-point would be the rubber seal under water pressure. Time will tell. I had one casio that lasted 10 years.
Update 28-Feb-2016: I have had this watch for over 4 years and it is still going strong. I go out into the sea at least once a week.
