Hey guys I don't know if you have heard about these. But I ordered a couple out of curiosity. These are an awesome way of changing up a basic G to just about any color you want. They do collaborations customs Right now they are available for the 6900 only. But they do have them coming out for the GA100/110 series as well. I think these are a really good and cheap way to take a basic 6900 and change it up into a really cool G shock in secs. Each one comes with its own watchband pin tool. You have to take the original band off. Then you can just slip the watch head itself into any color you want or have. I only ordered two for now to see if I would like then. The functions of the watch including the recessed setting button are all accessible with these on the watch. They are a super soft ,,,buttery soft silicone. Very nice. Right now you can order 5 colors for 100.00 Not too bad. The one on the left is the very basic DW6900-1V and the one on the right is My DW6900-MS1. Its kind of a cool way of dressing up a G your bored with. Or if you only have one ^900,,for the price of a single G you could order 5 different colors and Bam!!! you have 5 different looks for the very same watch. I wasn't sure if I could post the actual website where you can order these so if anyone would like to find them PM me and Ill give the website to you. All and all these are really cool. The only problem I can see is if you have a tiny wrist and already don't like the size of the 6900, these DO add a bit of bulk to the watch. So keep that in mind if you get some of these.
