Essential Tools for Every Modifier
1. Spring Bar Tool (Must-Have)
The spring bar tool is the single most important tool for G Shock modification. It’s used to remove and install the pins that hold your strap to the watch case.
- Price: $5-$20
- What to look for: Forked end for leverage, thin enough to fit between strap and case
- Recommended brands: Bergeon, Horotec, or budget options from Amazon
💡 Pro Tip: Invest in a quality spring bar tool. Cheap ones can bend or break, potentially scratching your watch.

For any modification that requires accessing the inside of your watch, you’ll need a case back opener. G Shocks typically use snap-off case backs.
- Price: $8-$30

3. Precision Tweezers
Tweezers are essential for handling small parts like spring bars, screws, and dial components.
