The G-SHOCK GMC-2500-1A8DR is G-SHOCK stripped back to reading the time. A two-eye layout puts a small seconds sub-dial and a date wheel on a brass dial, finished by sunray or honing depending on the colourway, inside the octagonal case shape taken from the DW-5000C — the first G-SHOCK. The date window is coloured to match the dial so it recedes rather than interrupts, and the hands are parallel-line designs echoing the raised bar indexes.

The engineering that makes this work is unusual: the minute hand is a Shock Release Hand, attached by magnetic force. On impact it gives rather than resists, absorbing the shock and returning to position afterwards. It is a different answer to the same problem the resin case solves, and it is why a thin-handed analog can carry shock-resistant construction and 200-metre water resistance at 68 grams.

A seconds hand sleep function parks the seconds hand to save battery, and the LED is amber rather than the usual white — warmer against a metal dial. The hand shift feature moves the hands clear of the sub-dial on demand.

Why You'll Love It

  • A brass dial is rare at this level. Sunray or honing finishing gives it a depth and a shift under light that a printed resin dial cannot reach, and Casio lists polished metal as a headline feature of this model.
  • The Shock Release Hand is a genuinely different approach to shock protection — the minute hand is held magnetically, so it absorbs an impact by moving with it rather than taking the force, then returns.
  • The two-eye layout keeps the face calm. A small seconds sub-dial and a colour-matched date wheel give you everything you need and nothing you don't, which is unusual for a G-SHOCK.
  • 68 grams and 12.9mm thick is light and slim for a 200-metre shock-resistant watch, so it works through a desk day as easily as a weekend.
  • The octagonal case traces directly to the DW-5000C, so the shape has a line back to the original G-SHOCK rather than a generic sports profile.
  • The seconds hand sleep function parks the seconds hand to conserve the battery, and the amber LED with afterglow reads warmer against metal than a white light would.

Key Features

  • Brass dial with sunray or honing finish — the finish varies by colourway, with raised bar indexes and parallel-line hands designed to echo them.
  • Two-eye layout — a small seconds sub-dial alongside a mode-function date wheel, with a three-cell date window coloured to match the dial so it sits quietly. The seconds hand carries the Shock Resist mark.
  • Shock Release Hand — the minute hand is attached by magnetic force, absorbing impact by giving way rather than resisting, then returning to position.
  • Shock-resistant construction with 200-metre water resistance (20 BAR) — rated for swimming, snorkelling and recreational water sports. Not rated for saturation diving.
  • Seconds hand sleep function — parks the seconds hand to conserve battery life.
  • Hand shift feature — the hands move clear of the sub-dial on demand for an unobstructed read.
  • Amber LED light with afterglow — a warmer light than the white LEDs used across most of the range.
  • Stopwatch and calendar — 1-second stopwatch with a 30-minute capacity in elapsed-time mode, plus a full auto-calendar to 2099 and Neobrite luminous treatment.
  • Resin and stainless steel case with bio-based resin band — 46.7 × 43.8 × 12.9mm at 68 grams, adjustable from 145mm to 215mm.

Technical Specifications

The Casio G-SHOCK GMC-2500-1A8DR is a two-hand analog watch on module 5757 from the GMC-2500 series, built with a resin and stainless steel case around a brass dial in a two-eye layout. The case measures 46.7 × 43.8 × 12.9mm and weighs 68 grams, with mineral glass, Neobrite luminous treatment and a bio-based resin band adjustable from 145mm to 215mm, built to shock-resistant construction and rated to 200 metres of water resistance. The minute hand is a magnetically attached Shock Release Hand that absorbs impact, and the module adds a hand shift feature, a seconds hand sleep function, a 30-minute stopwatch and an amber LED light. Accuracy is ±15 seconds per month and battery life is approximately two years on a CR1025.

Frequently Asked Questions

Does this watch have a daily alarm?

No. The GMC-2500 has no daily alarm function. Casio has advised that some units may carry a product tag incorrectly listing one — the specification on this page is the correct one. If your tag shows an alarm, the tag is wrong, not the watch.

Why does the minute hand sometimes move after a knock?

That is the shock protection working as designed. Casio calls it the Shock Release Hand: the minute hand is held by magnetic force rather than fixed, so on impact it gives way and absorbs the force instead of taking it. It may shift briefly and then return to its correct position. This is normal behaviour for the GMC-2500 and not a fault.

What is the two-eye layout?

Two openings on the dial rather than a cluster of sub-dials: a small seconds sub-dial and a mode-function date wheel. The date window is coloured to match the dial so it reduces contrast and sits quietly within the design rather than cutting across it.

What does the seconds hand sleep function do?

It parks the seconds hand to conserve battery when continuous seconds display is not needed. The watch keeps correct time throughout — only the hand stops moving, and it resumes when you need it.

Why does the minute hand move in steps?

The minute hand advances every 20 seconds rather than sweeping continuously. This is normal for module 5757 and conserves battery. Timekeeping accuracy is unaffected at ±15 seconds per month.

Can I swim or dive with it?

You can swim and snorkel with it. 200-metre (20 BAR) water resistance covers swimming, surfing and recreational water sports. It is not rated for saturation diving or use with helium-based gas mixtures. Avoid operating the buttons while the watch is submerged.

How long does the battery last, and can I get it replaced?

Approximately two years on a single CR1025 cell. When it runs down, bring the watch to any City Chain outlet — having it changed by a service centre keeps the case seal correctly reseated, which protects the 200-metre rating.

What other versions are there in this series?

The GMC-2500 runs across five references sharing the same case, module and two-eye layout, with brass dials in black, silver and gold. The GMC-2500-1A is the other resin-band reference alongside this one, the GMC-2500D models pair the same movement with a metal band, and the GMC-2500G-9A is the gold reference. Everything structural stays the same across the family.

Can the resin band be shortened?

The bio-based resin band is a buckle-and-holes design covering 145mm to 215mm with no tooling required. Unlike a metal bracelet there are no links to remove, so there is no in-store sizing step — set it to the hole that fits and you are done.

What warranty does this watch come with?

The GMC-2500-1A8DR comes with Casio's official 1-year warranty when purchased from City Chain Singapore, an authorised Casio retailer.
