Casio G-shock watch GA-100B-4AER

From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness comes the Military Colored Layered Band Series.

Bi-colour moulding makes it possible to create a new type of layered band with different colours for the inner and outer surfaces. The inside surface colouring is visible from the edge of the band and through the band holes for an original look. The military motif of these models is highlighted by their colouring, which recalls the inner lining of a flight jacket.

The base model is the anti-magnetic GA100 analogue-digital watch, and the five colourways in the lineup are black, blue, orange, white and beige.
