Smaller, more compact and even more convenient. The new G-SHOCK GMA-P2100-4AER Watch is slightly smaller and more compact than its predecessors. The strap is also shorter, making it ideal for narrower wrists. Its dial is more minimalist and appears calmer than previous models. The case and strap of these watches are made from a bio-based resin that comes from renewable organic sources. This material should not only reduce CO2 emissions, but also minimise the environmental impact in general.
