While NFC technology is not new in a watch (contactless payment watch), it takes on a whole new dimension here thanks to the innovations developed: the internal structure of the watch remains completely unchanged; the technology, which is non-invasive, is integrated only in the sapphire crystal glass on Chapter 4 models or within the straps on Chapter 3 and 5 models. BA111OD is the first watchmaker to use the NFC function at your service.
