Abstract
Method of ultrasonic welding a watch crystal, the watch including a middle part which, with the crystal, delimits a watch case, the crystal including a top face oriented towards the user and an opposite bottom face oriented towards the watch cases, a digital display device being fixed to the bottom face of the crystal, a printed circuit board being disposed inside the watch case, underneath and remote from the digital display device, the digital display device being electrically connected to the printed circuit board by means of a zebra electrical connector, wherein, as the crystal is abutting on a shoulder arranged in the middle part, the ultrasounds are directed onto the shoulder to melt the shoulder and to lower the level of the crystal in the direction of the printed circuit board, so that the zebra connector is compressed between the digital display device and the printed circuit board.
