Casio G-SHOCK Watch GMC-2500-1AER

Presenting the Casio G-SHOCK Watch GMC-2500-1AER, the octagonal G-SHOCK case turned fully analogue. A stainless steel bezel with polished facets, engraved G-SHOCK at 12, frames a black dial with applied silver bar indices, silver hands, a small sub-dial at 9 and a date window at 3. The print WATER RESIST 20BAR sits above 6 and a matte black resin strap closes the look.

It runs on Casio module 5757. The 46.7 × 43.8 × 12.9 mm case pairs bio-based resin with stainless steel for just 68 g, with a mineral crystal, shock-resistant construction and 20 bar water resistance. A CR1025 battery lasts about 2 years, accuracy is ±15 seconds per month and an amber LED light plus Neobrite help at night. The hands move in 20-second steps, alongside a 1-second stopwatch up to 29:59'30'' and a full auto calendar to 2099.

G-SHOCK was born in 1983 with the DW-5000C, built by Casio to survive drops and knocks. That toughness still defines the line, and the octagonal case has become one of its best-known shapes, here with an analogue dial made to be read at a glance.

At TicTacArea we have been jewellers since 1993 and online since 1999. As an authorised official Casio distributor, we deliver this watch genuine and factory-new, in its official box with its documentation.
