The composite band GWF-A1000XC-1AJF is the latest addition to the GWFA1000 Series, the first analog models for the FROGMAN Series of G-SHOCK MASTER OF G ISO 200m diver-level water-resistant watches.

This model is the first of the FROGMAN lineup to come with a composite band with an extension mechanism on the buckle that allows it to be easily worn over a wet suit while diving. During normal wear, the mechanism can be folded up for a normal-length band. The band of the GWF-A1000XC-1A is made using carbon-reinforced resin, making the band both strong and lightweight.

The laminated carbon bezel of the GWF-A1000XC has a single orange layer for a distinctive look. This ties in with orange dial accents that unify the overall design scheme. The base model for this new addition is the GWFA1000, which introduced an analog face while maintaining the asymmetrical face design that has been part of this series since its inception in 1993. Large, luminescent hour and minute hands improve readability, and the face provides an intuitive indication of measurement information.

The monologue structure of these models incorporates the case and back cover into a single piece.
