Gave away this clock. Unfortunately, one of the hands was loose. We tried to fix it, but the eye can be very bad pull on the ring. This is not a problem. The supplier has responded promptly to my request and send me a replacement. I found interesting in this context, something that I have rediscovered in the statutes of Amazon: goods containing batteries or acids, you can not return it to Amazon for security reasons. In this case, probably not, even if I remove the battery. This is no problem in this case, because I will send them directly to the supplier. I hope the replacement watch is fine. I find the idea good and unobtrusive.
