The company is unacceptable from the moment the watch comes without a box, with a simple nylon strap and without battery safety (a tab on the button). If I exclude the above for now, I found the problem it had far more important... the hand was sticking at various points from the first minute of operation... I may have come across a faulty piece but the company is still unacceptable since the prerequisites were missing and at such a price.... especially when I see watches with 15 euros like skmei that have everything and a 2-year warranty.
