AE-1200 Metal Case Installation: Complete Royale Mod Tutorial
The Casio AE-1200 “Royale” is one of the most popular budget-friendly watches for modding enthusiasts. With its clean design and affordable price point, it’s the perfect candidate for a metal case upgrade. In this comprehensive guide, we’ll walk you through the complete AE-1200 metal case installation process, transforming your plastic Royale into a premium timepiece.
Why Choose Metal Over Plastic?
The stock AE-1200 comes with a resin (plastic) case that’s lightweight and durable, but lacks the premium feel many watch enthusiasts desire. Here’s why upgrading to a metal case is worth considering:
- Premium Aesthetics: Metal cases offer a more luxurious appearance with brushed or polished finishes
- Better Weight Distribution: The added heft provides a more substantial feel on the wrist
- Enhanced Durability: Metal is more resistant to scratches and impacts
- Increased Value: A modded AE-1200 with a metal case looks and feels like a much more expensive watch
- Customization Options: Metal cases come in various finishes including silver, gold, black, and rose gold
Required Tools and Parts
Before starting the AE-1200 metal case installation, gather these essential tools:
Essential Tools
- Case Back Wrench: For opening the case back
- Spring Bar Tool: For strap removal and installation
- Fine-Tip Tweezers: For handling small components
- Watchmaker’s Screwdriver Set: Phillips and flathead in various sizes
- Movement Holder: To secure the movement during work
- Cleaning Cloth: Microfiber for dust and fingerprint removal
- Case Press Tool: For resealing the case back
Required Parts
- AE-1200 Metal Case (compatible with AE-1200 movement)
- New case gasket (highly recommended)
- Replacement spring bars (if needed)
Understanding AE-1200 Case Structure
The AE-1200 has a relatively simple case construction compared to other G-Shock models:
- Case Back: Screw-down type with four corners
- Movement: Module 3458 (analog-digital)
- Crystal: Mineral glass (may need transfer to new case)
- Bezel: Integrated with the case on metal versions
Understanding this structure helps you plan the disassembly and reassembly process efficiently.
Step-by-Step Installation
Step 1: Removing the Original Case
- Remove the strap using the spring bar tool
- Place the watch face down on a soft cloth
- Use the case back wrench to unscrew the case back (turn counter-clockwise)
- Carefully remove the case back gasket and set it aside
- Gently lift out the movement module
- If the crystal is integrated with the movement, handle with extreme care
Pro Tip: Take photos at each step to remember how components fit together.
Step 2: Preparing the Metal Case
- Inspect the new metal case for any defects or debris
- Clean the inside with compressed air or a soft brush
- If the new case doesn’t include a crystal, carefully transfer the original
- Install a new gasket into the groove of the metal case
Important: Always use a new gasket for optimal water resistance.
Step 3: Installing the Movement
- Align the movement with the case opening
- Ensure the crown/buttons align with their respective holes
- Gently lower the movement into the case
- Check that the dial sits flush with the case
- Verify all buttons move freely and click properly
Step 4: Sealing and Testing
- Place the case back over the movement
- Align the screw threads carefully
- Hand-tighten first to avoid cross-threading
- Use the case wrench to fully tighten
- Perform a water resistance test
Water Resistance Considerations
Water resistance is crucial for any watch modification. Here’s what you need to know:
- Original Rating: The AE-1200 is rated for 100m water resistance
- After Metal Case: Rating may vary based on the quality of the metal case and gasket
- Testing: Always test water resistance after the mod
- Professional Testing: Consider having a watchmaker pressure test your work
Warning: Never swim or shower with a newly modded watch until you’ve verified its water resistance.
Professional Tips for Success
- Work in a Clean Environment: Dust particles can interfere with movement
- Use Proper Lighting: A desk lamp with magnification helps see small details
- Don’t Force Components: If something doesn’t fit, recheck alignment
- Keep Parts Organized: Use small containers to separate screws and components
- Take Your Time: Rushing leads to mistakes and damaged parts
- Have Extra Gaskets: They’re inexpensive and essential for water resistance
