Two new Casio G-Shock G-Line watches have been unveiled. The GLX-5600WHR24-2 and the GLX-5600KB-1 are designed in collaboration with others and available European customers. Both battery-powered watches can run for up to seven years and offer features like tide charts and a wide range of time zones.https://www.notebookcheck.net/Casio-reveals-new-G-Shock-G-Line-watches-with-tide-charts.893825.0.html
It would be great if the tide display showed real life graphs rather than the simple (and often wrong) sine waves based purely on high and low tide times.
