      Comments about Casio WS210H-1AV Tough Solar Moon Tide Graphs Watch:

      If you're like me, you are considering this product because you need a timing device while in dive mode (which your diving computer doesn't provide). The fact that this watch also provides a daily tide graph makes it doubly attractive for dive instructors.

      I purchased this watch last month and went diving with it last week, at depths of 25 meters with some mild current and surges. More critically, I was pressing buttons at 18 meters to test the stopwatch function. The watch did not flood or fog, and it continues to function as new. At roughly $30USD, there really is no need to upgrade your existing dive computer.

        Questions & Answers Powered by TurnTo®

        Questions about this item:

        Shopper  The description says this watch shows the tide level. Will it indicate a rising or falling tide?
        Steve S  Yes. This will show the entire tide schedule.
        Stefano D  I'm confused about the strap being described as steel. It looks like a resin in the photo, and how does it fasten? It is an adjustable buckle, or do links need to be removed/added for a fixed length?
        TYLER M  It's a plastic wrist band. It has an adjustable buckle with one pin that goes in the appropriate hole. 1 size fits all basically. I've had mine about 6 months and am pretty happy with it. I dive with it about 15-20 dives per week. No issues. I don't use the tide graph too often though.
        Mark B  Hordy Does this watch have an Illuminator light button to light up the time functions?????
        EIRINI Z  YES!!
