I've only had it for a few days, so the accuracy of the watch hasn't been tested enough; it will show in the future, but so far it is accurate. What impresses me is how lightweight and cheaply made it looks. The display is quite bright at the highest intensity, but at a cost, because the LCD screen isn't the best, as you can understand, making the other digits appear like a reflection on the dial. The radio has good and clear reception, and its volume, despite its small size, is satisfactory. Finally, the ability to project the time onto the wall or ceiling with the built-in projector is very useful. A fair choice at 30 euros. I gave it four instead of five stars because it looks like a cheap construction, as I mentioned before. Its durability will be shown by time. It will lose about 1 minute a month. But that's about how much all watches of this kind lose.
Update: on 8-11-2019: No, it doesn't lose!! The watch proves to be accurate!! That's very good.
Update: 31-8-2024: After 5 years of use, it proves to be reliable since it still works just fine, which is why I'm giving it one extra star.
