Casio G-Shock GMA-P2110B Arrives With Compact Octagonal Design and Monochrome Style
Casio has officially listed the new G-Shock GMA-P2110B on its international website, confirming two sleek monochrome models designed for fans of compact, rugged watches with a clean modern look. The new lineup includes the GMA-P2110B-1A in all-black and the GMA-P2110B-5A in an earthy brown finish.
Both models continue the popular octagonal case style that has become one of the most recognizable modern G-Shock designs. The shape follows the design language made famous by the GA-2100 series, but this version keeps things smaller, lighter, and more wearable for those who prefer a compact everyday watch.
What makes the GMA-P2110B stand out is its refined single-color styling. Casio describes the look as a modern monochromatic color scheme, and the effect is simple but striking. Instead of mixing multiple tones across the case, bezel, and strap, each model uses a unified color theme. The metallic bezel ring adds a subtle shine, giving the watch a more premium feel without making it look flashy.
The black version offers a stealthy, versatile look that can pair easily with casual or sporty outfits. The brown model brings a warmer, more natural tone, making it a good option for anyone who wants a G-Shock that feels rugged but slightly more understated.
The design also carries over several details from the standard GMA-P2110 series, including the slim metal ring insert and a clean bezel without large logo branding. The bar indexes are sharper and more defined than those found on some larger models, helping the dial remain easy to read while keeping the watch visually balanced.
Inside the GMA-P2110B is Casio’s 5730 module, which provides the practical everyday functions expected from a G-Shock. Features include a 1/100-second stopwatch, a 24-hour countdown timer, five daily alarms, an hourly time signal, world time support for 31 time zones and 48 cities, and a full auto-calendar programmed until 2099.
The watch also includes a hand-shift function, allowing the analog hands to move out of the way when they block the digital display. This is especially useful for quickly checking digital information without adjusting the angle of the watch.
Durability remains a major focus. The GMA-P2110B is rated for 200 meters of water resistance, making it suitable for swimming, outdoor use, and everyday exposure to water. The case measures 46 x 40.5 x 11.3 mm, and the watch weighs just 37 grams, keeping it light and comfortable on the wrist.
Power comes from a CR1025 battery, with an estimated battery life of around three years. Casio lists monthly accuracy at within 15 seconds, which is standard for this type of quartz G-Shock model.
Another notable detail is the use of bio-based resin for both the bezel and band. This fits with Casio’s ongoing move toward incorporating more renewable materials into its watch lineup, while still maintaining the toughness and flexibility that G-Shock watches are known for.
Casio has not yet announced pricing for the GMA-P2110B-1A or GMA-P2110B-5A. The official listing currently points buyers toward retail availability rather than offering direct purchase details. This is common for international product pages, so regional pricing and release timing may vary depending on the market.
With its compact size, octagonal case, monochrome styling, metallic bezel accent, 200-meter water resistance, and practical digital-analog feature set, the Casio G-Shock GMA-P2110B looks positioned as an appealing everyday watch for fans of minimalist design and classic G-Shock durability.
