## Description

Casio presents the G-Shock GA-2100-1AER, a men's analogue-digital quartz watch from the Carbon Core Octagon Series. This timepiece features carbon-reinforced resin casing for structural strength plus a black colour scheme throughout. The watch includes a mineral dial window with Neobrite luminous coating on the hands for visibility in dark conditions. Designed for adult males, this G-Shock model combines traditional analogue display with digital functionality. The silicone strap is secured with a buckle clasp, plus the watch weighs 51 grams for lightweight wear. The lithium battery powers the quartz movement for accurate timekeeping. The watch features dual illuminator technology with separate illumination for analogue or digital components, ensuring readability in low light conditions. The LED light offers selectable illumination duration of either 1.5 seconds or 3 seconds, with afterglow feature for extended visibility. Functional features include stopwatch for timing activities, countdown timer for intervals, perpetual calendar for automatic date adjustment, alarm for reminders, plus world time for tracking multiple time zones. Waterproof to 200 metres depth, this watch is suitable for diving or water activities. The mineral dial window provides clarity plus protection for the watch face. The GA-2100-1AER incorporates shock protection construction with Hollow Core Guard Structure, designed to defend the watch mechanism against impact or vibration. This technology enhances durability during active use or physical activities. The carbon-reinforced resin casing provides structural integrity whilst maintaining the lightweight 51-gram total weight. Model number GA-2100-1ADR, series number 2100, part of the G-Shock collection. Easy reader design with clear analogue plus digital displays for convenient time reading. The watch arrives ready to wear with battery installed.

Review: Good quality highly recommended - Brilliant strong and tough as you would expect from GShock the face is clear and easy to read in day and night more than happy with it.
Review: Durable, clear and stylish - This is an excellent watch. It’s very clear to read and is light enough for you not to notice it’s on, whilst at the same time being sturdy and durable. I’ve had Casios since I was a child but always the cheaper digital ones, which I’ve always found to be excellent in their own right. They never come off my wrist as they’re durable and waterproof enough not to need to worry. This watch is no different. In fact, the G-shock is just an upgrade in that regard. My only reservation is with the tiny LCD display, which is too small for me to read in anything other than direct sunlight. This down to me eyes, but others will feel the same. The watch has every feature you’d need and none that you wouldn’t. The hands are clear to read with just a glance from any angle and they retain their luminosity through the night (although this isn’t bright) to enable you to tell the time without pressing the light button. This saves battery over the years and is welcome. I have 7” wrists and it doesn’t feel too big or too small - just nicely chunky. It’s low profile too, which means you don’t bash it on every door frame that you pass or snag it every time you take your top off. I replaced the strap as soon as I got it, to a NATO style strap, so I can’t comment on the qualities of the strap. Buy with the utmost confidence. This is excellent.

### ⭐⭐⭐⭐⭐ Solid watch, nice size, definitely recommend.
*by T***. on 19 March 2026*

Great watch, just right size for my wrist compared to other G-shocks. Highly visible face which was essential for my eyes, no need for glasses. I did manage to set the time only with the help of YouTube videos. All in all I would highly recommend this watch. Keep an eye out for the other offers column to the right of the page. I got mine for €80.00 (£70.00), plus free postage. Thanks Amazon. Thomas.
