G-SHOCK GBX-H5600-2 - G-LIDE Tide Square
A blue band on a tide watch is close to on the nose, and it works anyway.
The GBX-H5600 is a G-LIDE model in G-SHOCK's 5600 Series, built around tide graph and moon phase data with step tracking alongside. The case is carbon-bio and bio-based resin, charged by solar or by a dedicated USB cable, and the whole watch weighs 47 grams.
Black face against a blue and light blue band, in a case 51.1 by 44.5 mm and 17.3 mm deep. Module 3586 connects to the CASIO WATCHES app over Bluetooth for time setting and tide location, and carries world time, a stopwatch, a countdown timer, alarms and a full auto-calendar. 200 m water resistant.
Light enough to forget on a wrist and specific enough to be worth choosing on purpose.
Perfect for: blue G-LIDE watches, tide graph surf watches, lightweight square digital watches.
