Decimal Day Progress Watchface

A novelty Garmin watchface that displays time as decimal day progress (French Revolutionary Time style) instead of traditional 12/24 hour format!

Concept

Instead of the traditional 12-hour clock, this watchface divides the day into 10 equal parts and displays your progress through the day as a decimal number from 0 to 10.

Time Conversions

• Midnight (00:00) → 0.0
• 6:00 AM → 2.5
• Noon (12:00) → 5.0
• 6:00 PM → 7.5
• End of day (24:00) → 10.0

Features

• Analog watchface with 10 divisions (0-9)
• Rotating red hand showing current day progress
• Digital decimal time display
• Clean, minimalist design
• Supports most modern Garmin devices

Building the Watchface

Prerequisites

1. Garmin Connect IQ SDK - Download from developer.garmin.com
2. Java Development Kit (JDK) - OpenJDK recommended
3. Visual Studio Code (optional but recommended)
4. Garmin Monkey C Extension for VS Code (optional)

Build Methods

Method 1: Using Visual Studio Code

1. Open this folder in VS Code
2. Ensure the Monkey C extension is installed
3. Press the play button in the toolbar
4. Select your target device from the simulator

Method 2: Using Command Line

If you have the SDK installed and $SDK_PATH set:

# Build for simulator
$SDK_PATH/bin/monkeyc \
    -o DecimalWatchFace.prg \
    -f monkey.jungle \
    -y $SDK_PATH/bin/developer_key

# Run in simulator
$SDK_PATH/bin/connectiq

Method 3: Using monkeybrains (if available)

monkeybrains build
monkeybrains run

Deploying to a Real Device

1. Build the .prg file using one of the methods above
2. Connect your Garmin device via USB
3. Copy the .prg file to the GARMIN/APPS folder on your device
4. Safely disconnect the device
5. The watchface should now be available in your watchface selection menu

How It Works

The watchface calculates decimal time using the formula:

decimalTime = (hours + minutes/60 + seconds/3600) / 24 * 10

This value (0.0 to 10.0) is then displayed:

• Graphically via a rotating red hand on an analog face
• Digitally as a decimal number at the bottom of the screen

Supported Devices

This watchface supports a wide range of Garmin devices including:

• Fenix series (5, 5 Plus, 6, 7)
• Forerunner series (245, 645, 945, 955)
• Vivoactive series (3, 4)
• Venu series (1, 2, 2 Plus)

See manifest.xml for the complete list.

Notes

• The launcher icon is currently a placeholder - you can replace it with your own PNG image
• The watchface uses a simple black background with white/red elements
• Updates occur every second when active to show smooth hand movement

Future Enhancements

Potential improvements:

• Add date display
• Battery indicator
• Step count or other fitness metrics
• Customizable colors via settings
• Different hand styles
• AMOLED-optimized always-on mode
