G-SHOCK for Surf Conditions

The GBX-100NS-1 is a digital G-SHOCK built for surfers who need tide data, moon phase and daylight times on the wrist. Smartphone connectivity syncs the watch to 3,300 surf spots worldwide so local conditions are displayed instantly. The high-resolution MIP LCD keeps graphs and numbers readable in bright sun or low light.

200-Metre Water Resistance Limit

The case is rated to 200 metres, which covers surfing, swimming and recreational diving but not professional saturation diving. Mineral crystal protects the display from everyday impacts. Resin case and strap resist saltwater corrosion and stay light on the wrist during long sessions.

Tide, Moon and Calendar Capacity

Tide graphs show high and low times with levels, while moon age and phase appear for any date. Stopwatch measures up to 99 hours 59 minutes 59 seconds in 1-second steps with split-time function. Full auto-calendar runs to year 2099 in both 12- and 24-hour formats.

Questions about this item

Which colour or style variant of the GBX-100NS-1 should I pick?

The GBX-100NS-1 comes in a single black resin case with a black digital dial and matching resin strap; there are no alternative colours or case sizes listed for this model.

How does the 200 m water-resistance rating hold up during actual surf sessions?

A 200 m rating means the watch is built for professional marine activity and serious surface water sports, so it handles repeated immersion, wave impact and salt water without issue.

What does the 3,300 surf-spot database actually give me on the watch face?

Once a spot is selected in the paired app, the watch displays tide graphs, high and low tide times and levels, moon age, moon phase, and sunrise or sunset times for that location.
