The community take
Owners talk.
The Casio GM-H5600 is praised for its exceptional comfort, with the case back and strap combination allowing it to sit perfectly on the wrist without hotspots, and owners appreciate its low-light legibility and strong vibration alarm. Some owners find the strap significantly better than other 5600 models and note the watch is not as bulky as perceived. The GM-H5600 is considered more sensible on the wrist than the DW-H5600 due to its lighter weight. However, owners report poor battery life, with figures around 30-35 hours when using features like the HR sensor, and some find the tracking and cardio features do not work well. One owner reported connectivity issues with the app. Overall, owners rate the Casio GM-H5600 highly for its comfort and wearability, despite noted issues with battery life and feature performance.
