A G-Shock watch with a tide graph and moon chart is a useful tool for a variety of outdoor activities such as surfing, fishing, boating, kayaking, and beach combing. While a tide watch is not meant to be the only resource for proper trip planning, it is a convenient way to have quick access to ocean conditions as it can give you the tide level and moon age for the current time as well as at a specific date and time in the future. Here are all the Casio G-Shock watches available featuring tide and moon data for all your beach and ocean needs.
The Gulfman G-9100 is known as the “Rust Resist” G-Shock with its external metal parts made of a titanium alloy. That combined with its tide and moon phase graphs make it a good choice for seafaring use. The Gulfman is a straightforward model that would serve one well on the job. It brings to mind the G-Shock lineup of the 2000s when G-Shock watches were still medium-sized and mostly digital-display models.
There is also a GW-9110 Tough Solar/Multi-Band 6 version, though it is only available as an import.
G-Shock G-LIDE Series
The G-Shock G-LIDE series is designed for action sports and the following models are part of its designated surfing lines.
The GAX-100 series is a recent addition to the G-LIDE line. Housed in the popular GA-100-style large case, the GAX-100 is an analog-digital model with a tide chart and moon graph and also a thermometer sensor.
The GLX-5600 has a low profile of 12.7mm which is considered very slim for a G-Shock. The tide and moon data will help surfers determine when the waves will be at their peak. The smaller size of the GLX-5600 also makes it a good choice for anyone who wants a tide watch that is as unobtrusive as possible. Also see the GLX-5600F Floral Series featuring a Hawaiian floral print motif.
The GWX-5600C-4 is a glossy red Tough Solar/Multi-Band 6 tide watch.
The GWX-8900 is a Tough Solar/Multi-Band 6 surfing and tide watch with a larger case.
The GLX-150 is another large-case G-LIDE model that features a high-tech look. The tide and moon phase graphs are integrated very well into the display of this watch and it has a clean, appealing design with nice angles.
G-Shock G-7900 and GW-7900 G-RESCUE Series
The G-Shock G-9700 G-RESCUEseries is designed for emergency and rescue workers. The large case and buttons allow the watch to be operated when wearing gloves. The tide graph and moon chart make this series a good choice for coast guard personnel and boaters.
The GW-9700B-1 has Tough Solar and Multi-Band 6. Its dark reverse display gives it an extra-tough look though some may find it more difficult to view than a standard LCD display.
There is also a GW-7900-1ER with a standard LCD display but as an import G-Shock model it costs a lot more.
G-Shock Gulfmaster: GWN-1000, GWN-Q1000, and GN-1000
The Gulfmaster GWN-1000 is G-Shock’s flagship maritime model featuring a Triple Sensor (altimeter/barometer, compass, and thermometer) as well as a tide graph and moon age data. The GWN-1000 does not have a dedicated moon phase graph like the other watches on this list but it does display the moon age as a numerical value on the LCD display.
The Gulfmaster GWN-Q1000 is the latest Gulfmaster model and the first G-Shock with a Quad Sensor which includes a water depth meter, altimeter, barometer, compass, and thermometer. Other new features include sunrise/sunset data, a sapphire crystal. Like the GWN-1000 it has a tide graph and the moon age data is available on the LCD display.
The Gulfmaster GN-1000 is a more affordable battery-powered model with a Twin Sensor (compass and thermometer) and tide and moon data. It does not have Tough Solar or Multi-Band 6 like the GWN-1000 above, but it does have a dedicated moon phase display.
G-Shock Frogman GWF-1000
The GWF-1000 Frogman is G-Shock’s flagship diving watch featuring ISO 200-meter water resistance, Tough Solar, Multi-Band 6, and tide and moon graphs. The Frogman represents the top of the all-digital G-Shock family, has a full stainless steel body, and is manufactured in Japan.
