Casio G-SHOCK Watch GMC-2500G-9AER

Presenting the Casio G-SHOCK Watch GMC-2500G-9AER, an analogue G-SHOCK with a two-eye dial in the octagonal case. The eight-sided bezel is ion-plated in a gold tone, brushed on top with polished bevels, and carries the G-SHOCK lettering at six o'clock. The silver-white sunburst dial shows raised bar indices, gold-tone hands, a small seconds subdial on the right and a date window on the left. A black resin strap completes the watch.

Inside is Casio module 5757, powered by a CR1025 battery lasting approximately 2 years, with an accuracy of ±15 seconds per month. The case and bezel combine bio-based resin and stainless steel in a shock-resistant build measuring 46.7 × 43.8 × 12.9 mm and weighing 68 g, with a mineral crystal and 20 bar water resistance. Functions include a 1-second stopwatch measuring elapsed time up to 29:59'30'', a full auto calendar to 2099, an amber LED light and Neobrite luminous material.

G-SHOCK was born in 1983, when Casio engineer Kikuo Ibe set out to build a watch that could survive a fall. The first model, the DW-5000C, set the shock-resistant standard the line still follows today. The GMC-2500 carries that heritage over to a purely analogue dial designed to be read at a glance.

At TicTacArea, jewellers since 1993 and online since 1999, we are an authorised official Casio distributor: your GMC-2500G-9AER arrives genuine and factory-new, in its official Casio box with its documentation.
