Using your G - Shock GBX100 - 2 G - Lide watch is a piece of cake. To access surfer - specific info like tide times, just connect your watch to the phone app and select your location. You can use the training functions to keep track of your surfing performance. Press the appropriate buttons to start, stop, or pause measurements. When it comes to alarms, set them according to your schedule and decide if you want a vibration or tone. For timekeeping, switch between 12 - hour and 24 - hour formats as you like. Now, for the important stuff. This watch is shock - resistant and 200 - meter water - resistant, but don't subject it to extreme impacts or deep - sea diving beyond its limits. Keep the buttons dry and avoid pressing them underwater. To maintain your watch, wipe it with a soft cloth after use, especially if it gets wet. When the battery starts to run low (after about 2 years), replace the CR2032 battery. If you're traveling, use the world time function to set the correct time in different time zones, and remember to adjust for daylight saving time if needed.
