For fans of precision: the countdown timers help you to remember specific or recurring events by giving off an audible signal at a preset time. They The time can be set to the nearest second and up to 24 hours in advance. While the module is not Bluetooth connected or solar-powered, there’s a certain level of reliability that can be appreciated by a watch you set yourself and that’s powered by replaceable batteries. Not to mention, this allows Casio to offer a solid dial — versus a semi-transparent dial that’s required for sunlight to enter on a solar-powered watch — with the attractive vertical brushed vapor finish. There are almost always trade-offs, and this is a good one considering the dial, to me, is one of the primary highlights of this watch.With the GM2100 series, you get the hype of the CasiOak — which is named for its resemblance to watch designer Gerald Genta’s famous octagonal Royal Oak design — now in a more durable and premium metal-clad version, and for a very reasonable price. Perfect for free diving without scuba gear: the watch is water resistant up to 20 bar according to ISO 22810. On the wrist, I expected the 44 mm diameter to be cumbersome and a bit too large for my wrist and personal taste, but in reality, the case feels more like a 40 or 42 mm, primarily because the hinges on the left and right sides of the case add to the diameter but don’t make the watch wear as large as the dimensions suggest. I’ve yet to try on the smaller GMS2100 Series, which measures 40 mm in diameter, but I imagine it will have similar real-life wearability, which is to say it will likely wear small and comfortably as well — which is a good thing. At 11.8 mm, the case is incredibly thin and greatly enhances the incredible ergonomics. The lug-to-lug at 48.5 mm is also a key factor in why this watch wears so well (Casio’s official specifications state that it’s 49.3 lug-to-lug).

Synthetic resin is the ideal material for wrist straps thanks to its extremely durable and flexible properties. In my experience, the brushed surface of the bezel holds up well, even with significant impacts. However, I’m not sure how durable the polished portion of the case will be, although on the sample units the only noticeable scratches were actually on the bezel, which you may notice in some of the photos in this review.
