Casio Men's Analogue-Digital Quartz Watch with Plastic Strap GM-2100-1AER

Product Information

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).

There are 5 daily alarms available to set and an on/off hourly time signal, as well as a battery level indicator so you can ensure that the battery has received enough sunlight/artificial light. To conserve energy, the Power Saving features blanks out the display automatically when not in use (left in the dark). Elapsed time, split time and final time are measured with 1/100-sec accuracy. The watch can measure times of up to 24 hours. Technical amendments and errors excepted. The sizes in figures do not correspond to the original sizes. Pressing a button on the watch records the date, time, and position on a map, which is then viewable within the Casio Watches App. The watch can remind you of up to five upcoming events, which you set within the app. There’s a phone finder function activated from the watch. A mixture of vapor deposition and grind mark finishing on the outer ring and indices, respectively, adds a luxurious texture to the dial. On The WristMeasuring Capacity: 24 hours, Measuring Modes: Elapsed time, split time, Measuring Unit: 1/100 second (for the first 60 minutes) 1 second (after 60 minutes) The daily alarm reminds you about recurring events with an acoustic signal at the time you have set. This model has 5 independent alarms for flexible reminders of important appointments. 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.

Synthetic resin is the ideal material for wrist straps thanks to its extremely durable and flexible properties. Signal Range: Up to 2m (may differ depending on surrounding conditions), Auto time adjustment, Easy watch setting, Approximately 300 world time cities, Time & place and Phone finder using the CASIO CONNECTED APP The high-brightness double LED light can be set to illuminate the dial for 1.5 or 3 seconds, at the push of a button, and includes afterglow. This is the same for both the GMB2100 and the GM2100.

Reviews

The button tones for using the mode button can be turned off. This means that the watch no longer beeps when switching from one function to another. Preset alarm or countdown timers remain active when the button tones are deactivated. Perfect for free diving without scuba gear: the watch is water resistant up to 20 bar according to ISO 22810. The built-in stopwatch is accurate to 1/100th of a second for the first 60 minutes, after which the accuracy changes to one second, and the total measuring capacity of 24 hours. You can measure elapsed time and lap/split time and there’s also a 60-minute countdown timer. Powered by any light source, saving time and money as no battery change required- known as TOUGH SOLAR
