  • Our take on the Casio G-Shock GM2100-1ASW Men's Analog Digital Resin Watch

    The GM2100-1A is Casio's metal-clad take on the classic 2100 'CasiOak' octagonal G-Shock. A stainless steel bezel sits over a black resin case, giving it the look of a steel sports watch while keeping the shock resistance and light weight of a G-Shock. It runs on quartz analog-digital movement with 200m water resistance, world time, stopwatch, countdown timer, alarms and an LED light. It suits people who want a rugged everyday watch that dresses up better than an all-resin G-Shock, and it undercuts steel-bezel rivals on features per dollar while staying tougher than most fashion watches at the same level.

    Best forEveryday wear with casual or smart-casual outfitsBuyers who want G-Shock toughness in a steel-look caseTravelers who use world time and dual time zonesGifts for men who prefer analog hands over a pure digital display
    Pros
    • Stainless steel bezel over a shock-resistant resin case
    • 200m water resistance, fine for swimming and snorkeling
    • Analog-digital display with world time, stopwatch, timer and alarms
    • Slimmer and lighter than most full-steel G-Shocks
    • Octagonal case shape reads as a steel sports watch, not a plastic beater
    Cons
    • Mineral glass, not sapphire, so it scratches more easily
    • Negative LCD subdial is small and hard to read in low light
    • Resin strap and caseback feel less premium than the steel bezel suggests
    • No Bluetooth or solar charging, unlike higher-tier G-Shocks

    What reviewers say

    Owners like the GM2100-1A for its looks: it reads as a steel watch but wears light and survives knocks. Most praise is about the case finish, comfort and toughness. Complaints focus on legibility of the small digital display and the mineral crystal.

    What people mention
    • BuildPraisedOwners say the steel bezel and resin case take knocks without visible damage.
    • LegibilityCriticisedThe negative LCD subdial is dim and small, so digital readouts are hard to see in low light.
    • ComfortPraisedThe resin strap and light case make it comfortable for all-day wear.
    • CrystalCriticisedSome owners report scratches on the mineral glass with normal use.
    • LooksPraisedBuyers say it looks like a steel sports watch and dresses up better than a resin G-Shock.

    Questions and answers

    Is the GM2100-1A good for swimming?
    Yes. It is rated to 20 ATM (200m), which covers swimming, snorkeling and showering. Casio does not rate it for scuba diving.
    How does it differ from a standard GA-2100?
    The GM2100 adds a stainless steel bezel and a metal dial ring over the same octagonal resin case. It looks more like a steel watch and weighs a little more.
    Does it have Bluetooth or solar charging?
    No. It runs on a standard quartz battery and has no Bluetooth link or Tough Solar. Setting time and world time is done with the buttons.
    How does the size compare with other G-Shocks?
    It is slimmer and smaller than chunky models like the GA-110, so it fits average wrists better. It still wears larger than a typical 40mm dress watch.
    What functions does it have?
    World time, a 1/100-second stopwatch, countdown timer, daily alarms, a full auto calendar and an LED light. The analog hands and digital display work together.
    Is the glass sapphire?
    No, it is mineral glass. It resists everyday knocks but scratches more easily than sapphire.
    Where is the Casio G-Shock GM2100-1ASW Men's Analog Digital Resin Watch cheapest?
    At Amazon, for $219.95, as of our latest check.
    Where can I buy the Casio G-Shock GM2100-1ASW Men's Analog Digital Resin Watch?
