# Bluetooth Watch Smart Sync Bluetooth Watch Smart Sync is an independent, open-source Android application for selected Bluetooth-enabled watches. The application communicates directly with compatible watches over Bluetooth and provides tools for synchronizing time, managing alarms and reminders, configuring watch settings, and using selected watch functions with your Android phone. For a complete list of supported watches, see the project's GitHub repository: https://github.com/izivkov/CasioGShockSmartSync ## Key Features ### No account required Connect directly to supported watches without requiring an account. ### Calendar Sync Send events from your Android calendars, including Google Calendar and other supported calendar providers, to compatible watch reminders. ### Automatic Timezone Use your phone's current time and timezone information to configure the watch when travelling. The application can synchronize local time, timezone, and daylight-saving settings on supported watches. ### Remote Control Use supported watch buttons to trigger selected actions on your phone, including: - Find Phone - Take Photo - Flashlight - Next Track - Voice Assistant - Other supported actions Some actions have Android or device-specific limitations. ### Alarm Management Read and configure alarms stored on supported watches directly from the application. ### Watch Settings Configure selected watch settings from your phone, depending on the capabilities of your watch. ### Battery Information View battery information on supported watch models. ### Time Synchronization The application can use the phone's current time and location information to configure the local time, timezone, daylight-saving settings, and supported Home Time settings on the watch. This can be particularly useful when travelling between timezones. ### Alarms View and configure the alarms stored on supported watches. Depending on the watch model, the application can display multiple alarms and the hourly signal (chime) setting. ### Calendar Events and Reminders View upcoming events from your Android calendars and send compatible events to the watch's reminder feature. Standard calendar events are supported. Some complex recurrence patterns may not be compatible with the reminder capabilities of a particular watch. ### Actions Supported watches can be configured to trigger selected phone actions through watch button presses. Available actions depend on the watch model and Android version. For example, supported actions may include finding your phone, taking a photo, controlling music, activating the flashlight, or launching a voice assistant. ## Open Source Bluetooth Watch Smart Sync is free and open-source software. The source code is publicly available on GitHub.

- Jul 13, 2026 42.5## ✨ Highlights ### 🌍 Local Mean & Solar Time Support Introduced advanced time synchronization options for users interested in astronomical and local geographic time: * **New Time Options**: You can now select between **System Time**, **Local Mean Time (LMT)**, and **Local Solar Time (LST)** directly from the Time screen. * **LMT Calculation**: Automatically calculates time based on your exact longitude (1° = 4 minutes offset from UTC). * **Local Solar Time**: Uses the `adhan2` library to calculate the "True Solar Time" based on the sun's actual position (Equation of Time). * **Watch Synchronization**: When you press "Send to Watch" or when the app syncs automatically, it now respects your selected time type, allowing your G-Shock to display LMT or LST. * **Persistent Settings**: Your time type selection is securely stored in the watch's internal "scratchpad" memory and persists across sessions.

### ℹ️ Educational Info Dialog * **Interactive Info Button**: Added a new information button next to the time zone selector with clear, brief explanations of what each time type represents. * **Multilingual Support**: Updated the info dialog and instructions with full translations for **11 languages**, including Arabic, Bulgarian, Catalan, Chinese, French, German, Hungarian, Japanese, Russian, and Spanish. ### ⚙️ Enhanced Automation & UI * **Automatic Action Saving**: Removed the manual "Send to Watch" button in the Actions screen. Settings are now saved automatically in the background 3 seconds after a change is made, or immediately upon leaving the screen. * **Simplified Instructions**: Streamlined the connection screen instructions across all languages, making it easier to understand how to pair and run actions. * **UI Spacing**: Improved the layout of the time screen with better spacing for easier interaction. ### 🛠 Reliability & Performance * **Connection Stability**: Added a brief 0.5s safety delay during the connection handshake to improve reliability with certain watch models. * **Real-Time Offset Clock**: The on-screen clock now dynamically updates to show the selected LMT or LST in real-time. - Jun 30, 2026 42.3New release 42.3
