## Description

CASIO WATCHES is the official Bluetooth companion app for CASIO, G-SHOCK, BABY-G, EDIFICE, PRO TREK and OCEANUS watches. The latest update refreshes the home screen with brand-matching backgrounds, at-a-glance watch status, recent activity and Life Log summaries. Important: on Android 12+ enable the “Nearby devices” permission for CASIO WATCHES in OS Settings → Applications → App permissions, then restart the app to restore automatic time synchronization.

The app lets you register watches, access user manuals, adjust time and world time settings via Bluetooth, set alarms, view activity data (steps, calories, heart rate), discover exclusive G-SHOCK content and earn BADGE COLLECTIONS for step milestones. MY G-SHOCK allows customization and ordering of unique G-SHOCK models. Requires Android 8.0+, a CASIO ID, and Bluetooth 4.0+; compatibility and features vary by watch model and device.
