Casio is a Japanese brand that markets high-performance, long-lasting gadgets on the international stage. It has diversified its lineup with modern, practical watches offering a wide range of functions and an ever-on-trend style. Through its G-Shock collection, the brand delivers ultra-rugged, precise, and multifunctional models built for any activity - even the most extreme. In the Capsule Fine Metallic series, meet this stunning gold-tone GM-2100YMG-9AER watch. It features a robust, shock-resistant case with an octagonal shape, a diameter of 44.40 mm, a length of 49.30 mm, and a thickness of 11.80 mm. Weighing 84 g, the case is crafted from glass-fiber-reinforced resin combined with stainless steel. A mineral glass crystal sits over the dial, and four pushers on either side of the case allow you to navigate the functions. Finally, the screw-back case ensures water resistance of 20 ATM - perfect for water sports.
This watch features a black dial that enhances its beauty while ensuring easy, clear timekeeping. At the center, two gold-toned hands are coated with a Neobrite treatment for excellent legibility in the dark. They sweep around the hour markers to display hours and minutes. A minute track runs along the outer edge of the dial to complete the time display. At 9 o'clock, a subdial shows the day of the week, while a digital screen sits at approximately 5 o'clock, displaying the time, calendar, and other watch functions. Finally, the brand name is printed beneath 12 o'clock as a signature.
This model is powered by a Japanese-origin quartz movement. A Casio-branded mechanism known for its performance and reliability, it runs on a battery with a 3-year lifespan.
Gold-toned, this strap sports an eye-catching design that will stand out on men's wrists. It is crafted from vapor-deposited colored silicone coated with urethane. A tang buckle keeps it securely fastened in any situation. This strap fits wrist circumferences from 145 to 215 mm.
With a water resistance rating of 20 atmospheres, equivalent to 200 meters, this model is what experts would confidently call a dive watch. Our watchmaking specialists agree that while this timepiece is more than capable of handling showers, baths, lap swimming, freediving, and recreational scuba diving, it is not designed for extreme deep-sea diving where pressure would ultimately compromise its seal. For serious professional divers looking to push depth limits, we recommend models rated at 30 atmospheres or more. We also advise against operating the pushers or crown while submerged, in order to maintain a perfect water-resistant seal.
