Slim, lightweight, compact watches with octagonal bezels and a monochromatic look. The new GMAS2100 series downsizes the popular GA2100 to create a simple and slim design. The octagonal bezel, flat face, simple bar hour markers, and carbon core guard structure that are distinctive features of the GA2100 are now available in a compact configuration. Available in store and online at Christies Jewellery and Watches

The dimensions are 46.2 x 42.9 x 11.2 millimetres, this is smaller than the GA-2100 which is the slimmest current G-Shock watch.
