G-Shock occupies such a lovely space in watch collecting. Yes, watch enthusiasts can spend an entire afternoon seriously discussing intricate movement finishing, case proportions and the minute details in a watch, then find themselves just as excited about a full resin watch from Casio. And for this new 2500 line, there’s plenty to enjoy here, and it certainly has got everyone’s attention.

The idea is straightforward enough. Take the ingenious and iconic design of the DW-5000C, the original G-Shock shape from 1983, and imagine it with an entirely analog display — and it’s so awesome. The 2500 line carries the familiar watch outline with hours, minutes, small seconds, and a date window with quite a bit more to do than meets the eye — we’ll touch on that again later.

G-Shock’s Power Move

Shape-wise, the case maintains the octagonal bezel associated with the original square, though it has softer curves that give it a rounder appearance. The plateau-like button guards on the sides remain part of the design, though slightly different as they protrude out slightly further and extend longer vertically.

And for the dial, it brings together broad hands, raised bar markers and a fan-like date window opening that shows three cells – a design that was focused on having “Depth in Shadow”. The small seconds is at nine o’clock, while the color-matched date window sits opposite at three o’clock. It’s a combination that I personally feel looks particularly good in the metal bezel versions, where it gives light a few extra surfaces to catch and play around with.

That date window is where things become especially interesting. Casio calls it a Multi-Mission Date, and its job changes with the function you want to use. Alongside the date, it can also display stopwatch minutes, mode and setting information. Set the year, month and day correctly, and the watch also functions as a perpetual calendar through 2099.

The minute hand also has a clever arrangement of its own. Casio’s Shock Release Hand uses magnetic force to hold it in place, allowing it to absorb and disperse impact. Hands are vulnerable parts of an analog watch, so this engineering touch was 100% appropriate for a G-Shock. There is, however, a small caveat, as an impact or vibration may temporarily move the minute hand out of position — though it will return to the correct position within a few minutes.

Users can also put the small seconds hand to sleep to reduce power consumption. The watch runs on a CR1025 battery with approximately two years of autonomy on the normal setting, and five years on power saver mode.

GMC-2500D with black dial

There are nine versions to choose from across three configurations. The resin GAC-2500 comes in black, dark green, white and yellow. At 47g, it is the lightest option, and the colors give the new shape a suitably playful starting point. The GMC-2500 combines a stainless steel bezel, brass dials and a resin strap. The black- and silver-dial versions have sunray finishes while the gold version has a honed finish. Then there is the GMC-2500D, which pairs the steel bezel with a steel bracelet and comes with a black or blue-gray dial. The bracelet recalls the metal 5000 series with a cleaner design, without the little dimples on each link.

Across the 2500 collection, shock-resistant construction is joined by water resistance to 200m, a mineral crystal and an LED light.

The launch in Singapore

G-Shock certainly made an occasion of the 2500’s launch in South East Asia. On 7 November 2026, regional guests gathered at IMBA Theatre at Singapore’s Gardens by the Bay, where immersive visuals filled the walls and floor of the space. Shingo Yamaga, the managing director of Casio South East Asia, welcomed guests, and a presentation traced the familiar digital square from the DW-5000C, through the ana-digi GA-2100 and on to the new 2500 series. The scale of it all made it clear just how much this new family means to the brand.

There was also a media panel earlier in the day that gave us a little more to think about when it came to the development of the 2500. Kevin Tan, Casio South East Asia’s senior marketing manager, brought the conversation back to the act of reading time. Coming from the brand’s usual fully digital or ana-digital displays, the 2500’s pair of hands is a pleasure for us watch enthusiasts: seeing at a glance how much of an hour has passed and how much remains, all on a classic 12-hour dial format. It’s an appealing starting point for G-Shock, especially when so much of daily life already happens through a screen.

Yosuke Nagayama, Casio’s global head of timepiece design, connected the design brief to younger buyers’ interest in objects with lasting value and distinct character. His explanation of the aforementioned “Depth in Shadow” was key to the decisions made when it came to the sculptural look and feel of the 2500. Architectural forms informed the way of the broad hands, raised indices and dial surfaces that catch light and cast shadows. The small seconds and date windows were intricately positioned to leave open space around them. Interestingly, the exterior also took inspiration from beetle exoskeletons and protective armor, bringing flowing curves to a structure designed to withstand impact.

Tomohiro Yuasa, a product planner in the timepiece division of Casio, described the brief that was given to him as well during the watch’s early development: It was a watch that could be worn for years without looking out of place. Casio’s experience with electronic timekeeping helped feed into a brand new analog quartz movement developed just for this line and made at Yamagata Casio, the mother factory we visited earlier this year. The factory’s expertise in precision mold making and movement assembly naturally provided a useful connection to the engineering behind this new display. For Tomoaki Nakamura, general manager of Casio South East Asia, G-Shock’s appeal across the region also meant they had to come back to the qualities that matter in everyday wear: durability, practicality, versatility, and an evident sense of quality and beauty.

The 2500 launch event in Singapore

Back at the launch event at IMBA, this message on versatility was shown in a rather fun expression. The projected face of the 2500 display became the floor for a runway show, with models pairing the watches with a series of different looks.
