These new models are smaller, thinner versions of the popular analog-digital GA-2100. Based on the concepts of metallic semi-transparent materials, the colors of these models have been specially selected for easy, all-season styling. The metallic feel of the hour markers is produced by vapor deposition. The dials of the GMA-S2100SK-2ADR and GMA-S2100SK-4ADR have a coating that is slightly polarized, creating a mysterious feel.
