Features
The composite band GWF-A1000C is the latest additions to the GWF-A1000 Series, the first analog model 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 center segments of the GWF-A1000C's band are made using fine resin making the bands both strong and lightweight.
The stainless steel bezel of GWF-A1000C sports a blue ion-plated (IP) finish and a yellow second hand for improved visibility.
The base model for this new addition is the GWF-A1000, 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 monocoque structure of this model incorporates the case and back cover into a single piece.
