Like all Casio models, the watch is powered by a Japanese quartz movement, delivering an accuracy of +/- 15 seconds per month. Time Functions: Digital hour / minute / seconds, date, day, stopwatch (1-sec), countdown timer, Four daily alarms with snooze, 12 / 24 hour format, World Time (29 time zones / 38 cities), hourly time signal, auto-light.

Tide information and sunrise/sunset times for about 3,300 locations around the world can easily be set using the dedicated app. Also provides comfort with a soft urethane band with slits that help with fit and allow water and sweat to escape.

The high-definition MIP LCD also improves visibility. Its ability to display tide graphs, moon data, high tide/low tide times and levels, and sunrise/sunset times is useful for surfers as it enables them to understand the tide situation in detail at a glance, which pairs well with the training measurement functions. Training Function: Display of distance, speed, pace, and other calculated values based on accelerometer, auto/manual lap times, Auto Pause, target alert setting (time, calories burned) on/off, training display customization The reason is simple: at a very similar cost, you get quite a few more features that are both interesting and practical, especially if you’re into surfing. And while the design is very similar, we think the stainless steel bezel gives GBX 100 an edge in terms of aesthetics. Even with only, basic notification coming from the phone the watch does send info to the Move App, whether iOS or Android, such as surf and training data, and you can even set goals within the App. And you can set surfing spots and other features and send them to the watch via the Move app. So the watch does communicate in a two-way nature, just not as far as phone notifications which are one-way only.

All the data can be viewed on the watch’s display or on your smartphone, using the Mobile link feature that pairs the two devices via Bluetooth connection. MovementAll of the G-Move data can also be conveniently viewed on your smartphone, using the Mobile link function that connects the watch with your phone via Bluetooth. Firstly, the watch wears slightly bigger since its rectangular case diameter is 50,9. Because of the larger stature, the watch is also a bit heavier, weighing 66g. Another difference worth pointing out in terms of the exterior is the material of the bezel. While Casio GBD200 is fully made from resin, this model features a stylish stainless steel bezel that makes the design a bit more sophisticated. Now let’s move on to the area in which we think GBX 100 edges out GBD 200 and that’s the feature set. Features
