ITEM#: 17910380

A digital compass takes continuous readings for 60 seconds to help find your bearings at sea, and a thermometer feature helps to keep you informed about the environment around you. A Tide Graphfeature lets you check tide conditions whenever you want, while a Moon age indicator shows a graphic representation of Moon data. Both of these functions also support activities on the sea. A hand shift feature temporarily moves hands out of the way with the press of a button for easy reading of digital display contents. The soft urethane band creates a secure fit around the entire case to form smooth-flowing lines. This also serves to relieve band tension and provide a comfortable fit to the wrist. The result is useful and highly practical functions packed into a form that maintains its comfort, even after long hours of wear. From functionality to design, everything about these new GULFMASTER models supports the men of the sea and their activities in harsh environments.

    I bought this watch for my husband. He couldn't stop pushing the buttons and using all the features it has to offer. We have had many G-Shock watches and this one has a much better back light that previous ones. Very impressed.

    I ordered this watch for my husband for Christmas, he was very excited when he received it. We live on the coast and enjoy boating. This tide watch will be very helpful when we are on the water. He has used Casio watches in past and still has several that he still uses. Hood product,would recommend.

    I purchased this watch as a surprise for my husband. He loves every bit of this watch. It does so much more than his other g shock watches. He is a fisherman and goes on Lake Erie frequently. This watch even tells you wave depth. Love this watch!

    Great watch. Great price for this gshock watch. It has a trendy, nautical loom. The blue is metallic and stand out nicely. My bf wore the watch to the beach and had no problems getting it wet. I want one for myself now.
