G-Shock 2500 Turns the Original Square Into a Fully Analog Watch

G-Shock has always had a way of making watch collectors loosen their collars.

The new 2500 series leans into that appeal by taking the familiar outline of the original 1983 DW-5000C and giving it a fully analog display, complete with broad hands, small seconds and a date window that does more than its placement suggests.

It’s still unmistakably a G-Shock, but the shift away from a digital or ana-digital layout gives this line a different kind of daily-wear charm.

At a glance

• G-Shock’s 2500 series reimagines the original square case language as an all-analog watch family.
• The line introduces a Multi-Mission Date display, a Shock Release Hand system and a quartz module developed for this series.
• Nine versions are listed across resin, stainless steel bezel and steel bracelet configurations, with Singapore pricing from SGD 189.

The square G-Shock gets a 12-hour dial

The 2500 keeps the octagonal bezel character associated with the original G-Shock square, though the case has been softened with rounder curves.

The side architecture remains important, with plateau-like button guards that extend slightly farther and run longer vertically than the familiar template.

On the dial, Casio has gone for broad central hands, raised bar markers and a small seconds display at nine o’clock.

The date aperture sits opposite at three o’clock, using a fan-like opening that shows three cells rather than a simple single window.

Casio describes the dial concept as “Depth in Shadow,” with sculptural surfaces intended to catch light and cast shadow across the hands, indices and openings.

That approach feels particularly natural on the metal-bezel versions, where the added material contrast gives the analog layout more depth than a flat utilitarian dial would allow.

A date window with more than one job

The most interesting functional detail is the Multi-Mission Date system.

Alongside the date, the same display can show stopwatch minutes, mode information and setting information.

When the year, month and day are set correctly, the watch also works as a full automatic calendar through 2099.

The central minute hand has its own G-Shock-specific solution.

Casio’s Shock Release Hand uses magnetic force to hold the hand in place, allowing it to absorb and disperse impact.

That matters because hands are among the more vulnerable parts of an analog watch, especially in a family built around impact resistance.

Casio notes that an impact or vibration may temporarily move the minute hand out of position, though it is designed to return to the correct position within a few minutes.

The small seconds hand can also be put to sleep to reduce power consumption.

Resin, metal bezel and full bracelet versions

The 2500 collection is divided into three configurations and nine versions.

The resin GAC-2500 comes in black, dark green, white and yellow, making it the most playful entry point in the family.

At 47g, it is also the lightest version listed.

The GMC-2500 adds a stainless steel bezel, brass dial and bio-based resin strap.

Black and silver dial versions use sunray finishes, while the gold version has a honed finish and a gold ion-plated bezel.

The GMC-2500D pairs the stainless steel bezel with a stainless steel bracelet and comes with either a black or blue-gray dial.

Its bracelet recalls the metal 5000 series, though with a cleaner link design that omits the small dimples.

Across the collection, the watches feature shock-resistant construction, 200m water resistance, a mineral crystal and an LED light.

Singapore launch and the design thinking behind it

G-Shock marked the Southeast Asia launch of the 2500 series on 7 November 2026 at IMBA Theatre at Singapore’s Gardens by the Bay.

The event used immersive visuals across the space and included a presentation that traced the line from the DW-5000C through the GA-2100 and on to the new 2500 series.

Shingo Yamaga, managing director of Casio South East Asia, welcomed guests at the event.

Earlier in the day, Kevin Tan, Casio South East Asia’s senior marketing manager, framed the new analog format around the simple pleasure of reading elapsed and remaining time at a glance on a classic 12-hour dial.

Yosuke Nagayama, Casio’s global head of timepiece design, linked the watch’s design brief to younger buyers’ interest in objects with lasting value and distinct character.

He also connected the exterior form to beetle exoskeletons and protective armor, references that suit a watch whose identity is still rooted in toughness.

Tomohiro Yuasa, a product planner in Casio’s timepiece division, described the early brief as a watch that could be worn for years without looking out of place.

Casio’s new analog quartz movement for the line is made at Yamagata Casio, the company’s mother factory.

Details & Specifications

The 2500 series works because it doesn’t try to make G-Shock dressy in the traditional sense.

Instead, it gives the square a clear analog identity while keeping the practical engineering and everyday resilience that made the shape worth revisiting in the first place.
