The clock itself works very well, but they only synchronizes once every 24 hours, and the reference point for this is the time at which the battery is inserted. Thus, it is inevitable given that if you have inserted the battery time on a late afternoon or evening, the clock to the time change only very late shows the correct time. Most radio clocks synchronize the morning at 4 and 5 respectively clock and is that OK. But if I have to carry out the time change of hand I do not need clock !! In addition, that even now when I renew or remove the battery shortly to set, I have to do this even when temperature sensor, otherwise no communication between the two devices takes place. This whole situation clearly leads to the devaluation. And therefore I can not watch this company recommend, because I'm assuming that the other watch manufacturer function similarly.
