A real disappointment as the product is of poor quality. This Swiss-made watch does not give the time .. There is indeed a bug "known" Withings: the watch drift 20 min per day. It may sound unbelievable for a quartz watch, but that is the case and there is no patch.
Moreover, the "double tap" that can be acknowledged the alarm clock that does not work. The bug is "known function" Withings can not solve problem.
Would you like to have a "bad time" (or just have the time on your wrist)? It's simple, do not purchase this product!
