All but one of the watches below is GD-X6900 which is slightly more expensive than the standard DW6900. The GD-Xs are wider, thicker, and feature 10 year battery life, full auto calendar (to 2099), flash and buzzer alerts,and the handy auto “Super Illuminator.” Otherwise they are G-Shock through and through with the durability, dependability, all resin band and case, accuracy, alarms, and timer as you would expect from them.
GD-X6900TC Tiger Stripe Camo G-Shock
One could speculate that the TC in its nomenclature refers to “Tiger Camouflage.” Casios’ description (in the translated Japanese) also includes references to duck, troops, military, jungle, tropical rain forest,and casual fashion.
But whatever it is that draws you to it, know that the GD-X watch is the largest 6900 layout and that it benefits from the G-Shock durability, 10 year battery life and extra readable “Super Illuminator” back-lighting. Released near the end of 2014 in Japan,this series has a retail price of Yen 17,500.
Recently these watches have shown up on the big shopping sites in the range of $90 to $100.
GD-X6900SP-1 Supra X G-shock
The illustrations don’t show well the polka-dot pattern that covers the entire band of this special, limited edition wrist watch.
Being a footwear manufacturer, it is no surprise that Supra is co-marketing shoes with the same pattern.
The back cover is co-branded and the packaging is fashioned with the dot pattern and Supra/G-shock brands. This watch may become collectible. It was released in several markets in August 2015 at Yen 19,000.
GD-X6900MC “Camouflage Series” G-Shock
Yet another camo design emerges, just when you though you had your fill of Duck Dynasty, in a few colorways to perhaps fill a hole in your (military themed part of) wardrobe that you may have overlooked.
Sometimes the pictures’ color is way off.
This watch will appeal to those who like really big plastic watches and who particularly like the pattern on the band, bezel, and dial. If you like it, you love it. If you don’t, it looks even dumber than Capri pants. These watches will be available soon at ShopCasio.com for $150 and the big shopping sites for around $130.
GD-S6900HT Heathered Color Series
As is the case with a lot of the entry-level fashion G-Shocks, the pattern and colorway are stretched almost seamlessly from end to end of the band, right through the bezel and dial.
In the case of the Heathered models, the finish is fabric-like, somewhat soft in presentation but on some models possess quite vivid colors. For those who color key their outfits to perfection, this series provides numerous co-ordination possibilities. Shipped earlier this year, this series is available for some fairly good prices (MSRP Yen 17,000).
GD-X6900PM-1 G-Shock Polarized Marble Series
“From the tough and rugged G-SHOCK lineup comes a collection of a new model that apply new print technology to create an innovative design motif,” says the blurb by Casio. This is a limited edition – collector’s alert! As a particularly dramatic artistic colorway this series also includes 5600 and GA110 versions to consider for your collection.
The case and band are decorated with a marbled pattern using a new polarizing printing process that shows a different view depending on the viewing angle. The result is an ever-changing look that is both dynamic and plenty of fun. (released February 2015 internationally)
