Casio's New GMA-P2110B G-Shock Goes Monochrome at $145
Casio just put two new G-Shock models on sale in the US — the GMA-P2110B-1A in black and the GMA-P2110B-5A in brown — priced at $145 each on Casio.com. Both are in stock as of September 27, 2026. The pair represent a clear shift in direction: where G-Shock typically leans into bold colorways and heavy sport aesthetics, these two are built around a single-color, low-key look aimed squarely at everyday wear.
The look
The GMA-P2110B keeps the signature octagonal bezel from the 2100 series — the same silhouette behind the GA-2100's cult following — but strips out the visual noise. Both models are monochromatic from band to bezel ring. The case measures 46 × 40.5 × 11.3 mm and weighs just 37 g, making it noticeably more compact than most G-Shocks on the shelf. The bezel and band use bio-based resin, and a metallic bezel ring adds a subtle premium touch without going full dress-watch. Casio has been moving toward biomass materials across its lineup — Casio's New G-Shock Mudmaster Arrives Outside Japan With a Magma Look and Biomass Build when it expanded outside Japan earlier this year.
The specs
It's a hybrid analog-digital watch, with mineral glass over the dial. The hand-shift function moves the analog hands out of the way so the digital display is fully readable — useful when you're checking a timer or alarm mid-run. Dual LEDs light up the analog and digital sections separately. Water resistance sits at 200m, so it handles swimming and diving without issue.
Feature-wise, you get world time across 31 time zones and 48 cities, a 1/100-second stopwatch, a 24-hour countdown timer, five daily alarms, and an auto calendar. Battery is a CR1025, rated for approximately three years.
Availability
Both models are live now in the US at $145. In Europe, the brown 5A variant is listed as coming soon on Casio's German, Dutch, and Spanish sites at €139, per Notebookcheck. The black 1A model has no confirmed listing outside the US yet. UK pricing and retail availability — Currys, John Lewis — remain unconfirmed. If the monochrome direction interests you, Casio had Casio Unveils New G-Shock with Sleek Monochrome Design and 200m Water Resistance before this full launch, so the rollout has been deliberate.
