GM-2100M-1AER

The iconic GM-5600 digital model, with its unmistakable square shape and metal bezel, together with the GM-2100 analogue-digital design, adopt an achromatic palette that enhances the elegance of simplicity and pure functionality.

The textured metal bezel, accompanied by a subtle red accent on the function label—symbolising G-SHOCK's commitment to absolute resistance—reinforces an aesthetic where every detail has a purpose.

Its uniquely designed bezel incorporates openings that reveal the interior of the case, highlighting the technological essence of G-SHOCK: a structure designed to withstand shocks and extreme conditions.

With a perfect balance of streamlined design, versatility and functionality, this watch is a durable piece, designed to accompany you for many years to come.
