I got a question from Zeroed4x if the bezel of a DW-6900 fits a GW-6900 case. I assumed that the bezels won't fit, because there is a small difference in height of both models. Zeroed4x replied that Casio Tech Support answered that the bezels will fit.
Well, I wasn't sure of my answer and Casio Tech Support seems to know what they are talking about. There is only way to find out if the bezels are interchangeable. I was reading my messages lazy in bed, listening Sunday shouting, so I got up and grabbed a G-6900, GW-6900 and a DW-6900.
Well, there is a little difference in the bumper/button protector on the side. The G-6900 bezel (on my GW-6900, these bezels are interchangeable) has a smaller bumper. In the Macro above you can see the DW-6900 is about 1mm higher.
In case of doubt: Left the DW-6900, right a G-6900.
After stripping the bezels off, more differences occurred. The DW-6900 has a recessed ADJUST button, while this is not on the G-6900. Note that there are also differences in the shape of the cases where the strap is attached.
Also Casio uses slightly longer screws on the G(W)-6900.
And then the final test. The shape of the case might be different and small differences appear on the bezel too, but that does not necessary mean that bezels would not be interchangeable.
The GW-6900 bezel does in no way even want to fit the DW-6900. It is somewhere too small, I can't even pull it over the buttons on one side. So will it fit: "NO"
Then the DW-6900 bezel over the G-6900. Witt some brute force I got it pulled over the buttons, but you feel that is isn't fitting over the whole case. Also I noticed the light button is slightly lower than on the DW-6900. It will not fit in any way you try. SO does a DW-6900 bezel fit a G(W)-6900? Anwer: "No!" Myth Busted.
Below a group photo of the participants: Pink DW-6900, black G-6900 with GW-6900 bezel and straps and yellow GW-6900 with G-6900 bezel and straps.
Conclusion: "Myth Busted!"
