Reviews

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Casio GA-800

The Casio GA-800 is widely praised for its legible analog dial, dual LED illumination, and precise second hand, with many owners appreciating its comfortable size and thinness compared to other G-Shocks. Reviewers and owners consistently highlight its value and well-thought-out ana-digi design, with some calling it the best G-Shock at its price point. However, some users wish for lumed hour markers, a more robust world time function, and lament the lack of solar and atomic capabilities. One owner reported unexpected resets after a battery change, and a stopwatch record storing function glitch affected some units. Accuracy is reported as around +7 seconds per month. Overall, owners rate the Casio GA-800 highly for its legibility and comfortable wearability at the price.

Casio GBA-400

Owners report the Casio GBA-400 is a rugged, 200m water-resistant Bluetooth watch that allows remote music control from a smartphone. The watch has demonstrated remarkable durability, with one owner noting it looked brand new after five years of use and various tortures. However, connectivity issues are noted, with one owner unable to connect to an iPhone and another reporting the app does not work with Android 12, while Bluetooth connectivity can be inconsistent and music controls may not work with all phones. Some owners also flag the crown as fragile, with one reporting it broke and required repair. Overall, owners rate the Casio GBA-400 highly for its durability and ruggedness, despite noted Bluetooth connectivity and crown fragility concerns.
