Works as expected. Always keeps perfect time. After several days of normal use indoors the watch reached a full charge and has stayed fully charged ever since. I never try to charge the watch by placing it in the light since there is no need. The watch has automatic power saving features when it is not worn but quickly wakes up again when picked up. The face illumination is legible and effective. Even with this occasional bumping and scraping there are still no marks on the watch after months of wear. The crystal is protected from damage by being recessed below the outer rim of the watch.
