Tools You’ll Need
Essential Tool: Spring Bar Tool
The only tool you absolutely need for strap replacement is a spring bar tool. This thin, forked tool allows you to compress the spring bar pins that hold your strap to the watch case.
- Price: $5-$20
- Where to buy: Amazon, watch supply stores, GshockMod store
- Features to look for: Forked end, comfortable grip, thin enough to fit between strap and case
💡 Pro Tip: If you don’t have a spring bar tool, you can use a small flathead screwdriver or even a stiff piece of plastic in a pinch. However, investing in a proper tool makes the job much easier and reduces the risk of scratching your watch.
Optional but Helpful Tools
- Microfiber cloth – To protect your watch and catch small parts ($2)
- Parts tray – To organize spring bars and screws ($5)
- Tweezers – For handling small spring bars ($5)
- Watch cushion – To hold your watch steady ($5)
Strap Width Guide by Model
Before buying a new strap, you must know the correct width for your G Shock model. Using the wrong size won’t fit and can damage your watch.
| Model Series | Strap Width | Notes |
|---|---|---|
| GA-2100 (Casioak) | 22mm | Most versatile size |
| GM-2100 (Metal Casioak) | 21mm | ⚠️ Different from GA-2100! |
| DW-5600 | 18mm | Classic square |
| DW-6900 | 20mm | Larger case |
| GWG-2000 (Mudmaster) | 24mm | Large tactical |
| GW-9400 (Frogman) | 24mm | Dive watch |
| F-91W | 18mm | Budget classic |
| A158WA | 18mm | Retro style |
| AE1200 | 22mm | Aviation themed |
⚠️ Important: The GM-2100 (Metal Casioak) uses a 21mm strap, while the GA-2100 uses 22mm. This is a common mistake! Always double-check your model before ordering.
Step-by-Step Strap Replacement Tutorial
Preparation (2 minutes)
- Set up your workspace – Find a clean, well-lit area with a flat surface
- Place a microfiber cloth – This protects your watch and catches any small parts that might fall
- Organize your tools – Have your spring bar tool and new strap ready
- Remove your watch – Take it off your wrist and place it face-down on the cloth
Removing the Old Strap (5-10 minutes)
Step 1: Locate the spring bar
Turn your watch over and look at where the strap connects to the case. You’ll see a small metal pin (the spring bar) running through the strap end.
Step 2: Insert the spring bar tool
Take your spring bar tool and insert the forked end between the strap and the case lug (the part of the case that holds the strap). Position it so the fork catches the shoulder of the spring bar.
Step 3: Compress and release
Push down on the tool to compress the spring bar. While holding pressure, gently pull the strap away from the case. The strap should release.
💡 Pro Tip: If the strap is tight, try pushing the spring bar from different angles. Some straps fit more snugly than others.
Step 4: Remove the spring bar
Once the strap is off, push the spring bar out of the strap. Set it aside in your parts tray if you plan to reuse it.
Step 5: Repeat for the other side
Follow the same steps for the other side of the strap.
Installing the New Strap (5-10 minutes)
Step 1: Prepare the new strap
If your new strap came with spring bars, use those. If not, use the spring bars from your old strap. Insert a spring bar through one end of the new strap.
Step 2: Position the strap
Hold the strap in position against the case lug. Make sure the strap is facing the right direction (the end with the buckle goes at 12 o’clock).
Step 3: Insert one end of the spring bar
Place one end of the spring bar into the hole in the case lug. This end should stay in place while you work on the other end.
Step 4: Compress and seat the spring bar
Use your spring bar tool to compress the free end of the spring bar. Slide the strap into position and release the tool, allowing the spring bar to expand into the hole.
You should hear or feel a click when the spring bar seats properly.
Step 5: Verify the connection
Gently pull on the strap to make sure it’s securely attached. It should hold firmly without any movement. If it feels loose, remove and reinstall.
Step 6: Repeat for the other side
Follow the same steps for the other half of the strap.
Final Check (1 minute)
- Pull firmly on both straps to verify they’re secure
- Check that the buckle is at 12 o’clock
- Try the watch on to check fit and comfort

Troubleshooting Common Issues
Problem: Strap won’t release
Solution: Try approaching from different angles. Insert the tool from the top, bottom, or side. Some straps fit very tightly.
Problem: Spring bar keeps falling out
Solution: Check that your spring bars are the correct size. They should be slightly longer than the strap width (e.g., 22mm strap needs ~24mm spring bar).
Problem: Strap gaps at the lugs
Solution: This is usually a sign that the strap is too narrow. Try a wider strap or add small rubber washers to fill the gap.
Problem: Scratched the case
Solution: Use tape to protect the case lugs before starting. Light scratches can often be buffed out with a polishing cloth.
