G-SHOCK Bezel and Strap Replacement: What to Buy and How
Short answer
A G-SHOCK bezel and strap are separate parts, and both can be replaced without opening the watch. Buy by the model number on the case back, because each part is made for one case shape. You can fit an original resin part to restore the watch or an aftermarket metal or moissanite bezel to change its look, and replacing both takes about 15 minutes with a spring bar tool and a small screwdriver.
When does a G-SHOCK bezel or strap need replacing?
Resin wears with age and use. Casio's care instructions warn that leaving sweat or water on a resin band or bezel, or storing the watch somewhere very humid, can lead to premature wear, cuts and breaks.
Replace the part when the resin has cracked, split at the strap holes, gone sticky or discolored. The watch inside usually outlasts several sets of resin.
Are the bezel and the strap the same part?
No. The bezel is the cover around the watch face, held on by four small screws. The strap, or band, is two pieces attached at the top and bottom of the case by spring bars. They are sold separately, and you can replace one without the other.
Original or aftermarket replacement parts?
There are three kinds of replacement part, and they do different jobs.
- Original Casio resin parts restore the watch to how it left the factory. Ask Casio's service channels or an authorized retailer for the part made for your model.
- Aftermarket resin parts copy the original shape, usually in more colors. Fit and material quality vary by maker.
- Aftermarket metal and moissanite bezels change the look of the watch. They are upgrades, not like-for-like spares.
How to find the right part for your G-SHOCK
Read the model name and the four-digit module number on the case back, and buy a part that names that model. Bezels and straps are not interchangeable between case shapes: a DW-5600 part does not fit a DW-6900 or a GA-2100.
How to replace a G-SHOCK strap
On G-SHOCKs whose strap is held by spring bars, the strap comes off in a few steps.
- Step 1: Lay the watch face down on a soft cloth.
- Step 2: Push the end of the spring bar inward with a spring bar tool and ease that side of the strap out of the case.
- Step 3: Slide the spring bar out of the old strap and into the new one.
- Step 4: Seat one end of the bar in the case, compress the other end and let it click into place.
- Step 5: Pull the strap firmly in both directions to check that it is locked.
How to replace a G-SHOCK bezel
With the strap off, undo the four bezel screws, lift the old bezel away, seat the new one evenly and refit the screws. Our step-by-step guide covers the tools and the mistakes that strip screws.

Common questions
Can I replace only the bezel on a G-SHOCK?
Yes. The bezel and the strap are separate parts. Take the strap off to reach the bezel screws, swap the bezel and refit the same strap.
Are G-SHOCK straps and bezels interchangeable between models?
No. Each strap and bezel is made for one case shape. Match the model number on your case back to the model named on the part.
Is it worth replacing a G-SHOCK bezel?
Usually yes. The watch inside tends to outlast its resin, so a new bezel and strap make an old G-SHOCK look new for far less than a new watch.
Does GshockVendor sell G-SHOCK straps?
Not as separate resin straps. Our GA-2100 mod kits include a stainless steel band along with the steel case.
Do I need to open the case back to replace the bezel or strap?
No. Both come off from the outside. The case back and the movement stay closed.
