Casio is making its premium full-metal G-Shock chronograph lineup far more tempting right now, thanks to a steep limited-time discount on the GMCB2100D series at the Casio US outlet. Both the G-Shock GMCB2100D-1A and the G-Shock GMCB2100D-2A are currently marked down by 40%, dropping the price from $800 to $480. If you’ve had your eye on a Japan-made, full-metal G-Shock with classic analog styling and modern smart features, this is one of the better price cuts we’ve seen for this tier.
The GMCB2100D-1A stands out immediately for its larger presence compared to the GM-B2100. It uses a 46.3 mm stainless steel case paired with a metal bezel and a matching steel bracelet. The band includes a one-touch, three-fold clasp meant to make taking it on and off quick and secure. That said, this is not a subtle watch—anyone with smaller wrists may find it wears big.
It’s also built with the hefty feel you’d expect from an all-metal G-Shock. At roughly 171 grams (about 0.37 lbs), it sits on the heavier side for daily wear, which some collectors love for the “solid tool watch” vibe, while others may prefer something lighter for all-day comfort.
On the dial, Casio goes for a bold, black-finished look with three main hands (hour, minute, and seconds) plus three subdials showing dual time in a 24-hour format, minutes, and day. One trade-off at this price is the use of mineral glass rather than a higher-end crystal, but Casio balances that with one of its most practical advantages: Tough Solar charging. The brand says you can expect up to five months of operation on a single charge, which is a major plus if you want a grab-and-go watch that doesn’t constantly need attention.
Feature-wise, it checks a lot of boxes for a modern G-Shock chronograph. Along with standard timekeeping, you get Bluetooth connectivity for enhanced functionality, a 1-second stopwatch, a countdown timer, dual time support, a daily alarm, an LED light with afterglow for low-light visibility, and a battery level indicator so you’re not guessing when it’s time to get back under a light source.
Overall, the Casio G-Shock GMCB2100D-1A (and its sibling, the GMCB2100D-2A) looks like a strong value at $480 if you want a durable, full-metal, Japan-made G-Shock chronograph with solar power and Bluetooth. At full price it’s a tougher sell for some shoppers, but with this Casio outlet discount, it becomes a much more compelling pick for collectors and everyday wearers alike.
