Very good for its price. The battery does not charge with solar power, but it probably lasts longer than other watches because even with very little sunlight, it functions only with solar power!
Time will tell about its durability.
It is nice, large, and easy to read. So far, very satisfied.

Attention, the term 'Solar Charging' is incorrect. In English, it is described as solar, not solar charge. The battery it has is an sr626sw, a simple one, not rechargeable. All these watches operate in the same way: as long as the watch has sunlight, it receives power from the sun. When there is no sunlight, the watch receives power from a regular battery, which needs to be replaced after a few years. You don't gain much by having a solar watch unless you are exposed to sunlight for 12 hours!
