Casio US has cut three of the four red LCD models in its G-Shock Fine Metallic series by 20% for November. The square digital GM-5600YRA-8 drops to $216 from $270, and the analog-digital GM-2100YRA-8A and GM-110YRA-8A fall to $232 each from $290.
The 6900 isn’t part of it.
Fine Metallic sits between standard resin G-Shocks and the full metal lines: a stainless steel bezel up top, Casio’s Tough Silicone Band underneath, so the watch reads metal and wears soft. All four red LCD models reached the US in February 2026. These are the first US discounts on the red set.
GM-6900YRA-8, the round digital in the group, keeps its $270 list price and is out of stock at Casio US, though Amazon lists it at $250. The three sale models are all in stock at Casio, and since each suits a different wrist, the picks run smallest to largest.
What Fine Metallic actually changes
Casio polishes each stainless bezel with two finishes on the same part, a brushed hairline grain across the broad faces and a mirror polish on the edges, and the two surfaces catch light differently as your wrist turns. A coated resin case at this price can’t do it, and the effect is why these read closer to a $400 metal watch than to the resin G-Shocks they share a parts bin with.
The band loop parts are stainless steel too, so no plastic breaks the line anywhere on the watch.
Underneath, the Tough Silicone Band is built in layers: a soft silicone base, a urethane film over the top surface to shrug off scuffs, and a transparent underside carrying a silvery vapor deposition finish that continues the metal look around the back of your wrist.
Every watch in the set is shock resistant and water resistant to 200 meters, and the shared functions run to world time, a 1/100 second stopwatch, a countdown timer, five daily alarms and a full auto calendar. The core spec sheet barely changes from model to model. Pick on case shape and size.
GM-5600YRA-8 at $216
GM-5600YRA-8 is the direct descendant of the first G-Shock, and the square case still wears the smallest here at 49.6 by 43.2 by 12.9 mm, with module 3525 running a digital-only display set into a black frame that makes the red LCD look deeper than it does on the analog models, and it’s the easiest of the three to wear under a cuff. Battery life runs about five years, against roughly three for the two analog-digital models below, and at $216 it’s the cheapest way into the Fine Metallic treatment.

GM-2100YRA-8A at $232
GM-2100YRA-8A takes the octagonal 2100 case, the shape most buyers know as the CasiOak, and slims the watch to 11.8 mm thick at 84 g, the thinnest profile in the set. Module 5611 pairs analog hands with a red digital window in the lower half of the dial, world time covers 31 time zones across 48 cities, and a double LED lights the dial and the window after dark.
Take this one if you want the metal bezel without the bulk that usually comes with it. It matches the bigger 110 dollar for dollar at $232 and wears noticeably smaller doing it.

GM-110YRA-8A at $232
GM-110YRA-8A goes the other direction: 51.9 by 48.8 by 16.9 mm and 106 g, the largest footprint in the set by a wide margin. Module 5553 adds magnetic resistance the other modules skip, and hands plus layered dial furniture fill the face, with the red digital window cut in low.
Nothing on the shared spec sheet goes missing to get the size, though. Water resistance, alarms, world time, all of it carries over.
Big wrists should start here, and so should anyone who wants a G-Shock that reads as a statement piece across a room. The $232 sale price matches the slimmer 2100 exactly, so the only real decision between the two is how much watch your wrist wants to carry.

Sizes and prices side by side
Thickness runs from 11.8 mm on the 2100 to 16.9 mm on the 110, while pricing holds a simple two tier shape once the discount lands.
| Model | Case size | Module | Sale price | List price |
|---|---|---|---|---|
| GM-5600YRA-8 | 49.6 x 43.2 x 12.9 mm | 3525 | $216 | $270 |
| GM-2100YRA-8A | 49.3 x 44.4 x 11.8 mm | 5611 | $232 | $290 |
| GM-110YRA-8A | 51.9 x 48.8 x 16.9 mm | 5553 | $232 | $290 |
More looks at the finish
The fourth watch and the pick
Completionists should know the set has a fourth member: GM-6900YRA-8 keeps the round 6900 case, module 3230 and the same red LCD treatment at a $270 list price, but Casio US shows it out of stock and it sits outside the 20% cut. Amazon lists it at $250 if you want the full set now.
Buy the square if your wrist runs small. The 5600 at $216 is the original shape, the longest battery of the three, and the only one here that disappears under a cuff, and pocketing the $16 difference against the analog pair loses you nothing but hands. Buy the 2100 if you want the one you’ll actually wear daily: at $232, 11.8 mm thin and 84 g, it’s the Fine Metallic idea with the bulk engineered out, and it’s the pick of this sale.
Buy the 110 only if big is the point, because at the same $232 its extra size buys presence rather than function. And if the round 6900 is the shape you actually want, skip the sale entirely and take Amazon’s $250 listing. The discount doesn’t change which watch fits your wrist. It just makes the right one cheaper.
