Casio names four model families—GA-700HDS, GA-110HDS, GA-6900HDS and GA-2100HDS—with a shared white-and-blue theme and glow-in-the-dark dial details. Its UK listings provide specifications for three models; the 6900 listing is titled DW-6900HDS-7ER-F4, rather than GA-6900HDS.
What is in the Fantastic Four G-SHOCK collection?
Casio presents the watches as white-and-blue designs inspired by the Fantastic Four and their suits. The collection copy also describes sci-fi-inspired dials that glow in the dark, retro-futuristic 1960s packaging and Fantastic Four pin badge sets. Casio calls the collection limited, but does not state how many watches will be made. Casio UK’s collection and GA-700HDS listing
The collection is associated with The Fantastic Four: First Steps. Casio’s copy says the film is in cinemas Thursday July 24, without giving a year for that date. Casio UK

What the listings establish—and what they do not
Casio describes the collection as shock resistant and 200-metre water resistant, and the three reviewed product listings provide model-specific details for the watches they cover. The available information does not support a complete four-way comparison, including full specifications for the GA-110HDS. Check the exact product page before choosing a model rather than assuming the watches share every feature.

The official collection copy calls the range limited but does not give a production quantity. Current UK prices and stock for all four models are not established by the product-page information cited here, so check Casio’s live listings for availability and the precise model number before buying. A collection announcement or product page alone does not establish that a particular watch is currently in stock.
