Claims15
A watch glass comprising a near field communication module (NFC), the NFC module containing at least one microcircuit or a microprocessor connected to an antenna, wherein the watch glass comprises a lower layer comprising a groove in its upper periphery and a notch which is located in a lateral extension of the groove, and wherein the microcircuit or microprocessor is positioned in the notch, and wherein the antenna is positioned in the groove;
- and an upper layer comprising on its inner periphery a cover coating, said cover coating being positioned precisely on the groove and the notch during when the two layers are being bonded together, in order to hide the NFC module.
A method of producing a watch glass which comprises two layers, which define an upper layer and lower layer respectively, bonded together and an NFC module which contains at least one microcircuit or a microprocessor connected to an antenna, the method comprising the following steps:
- produce the upper layer which comprises on its inner periphery a cover coating;
- produce the lower layer by machining a groove in an upper periphery of the lower layer and machining a notch located in a lateral extension of the groove;
- produce from a single piece, the NFC module comprising at least one microcircuit or a microprocessor connected to an antenna;
- place the NFC module in the groove and notch of the lower layer;
- bond together the upper layer with the lower layer, positioning the cover coating on the groove and the notch when the two layers are glued, in order to conceal the NFC module.
