[0002] During the processing of the watch case, the watch head needs to be drilled. Drilling is a crucial part of the watch processing process. When drilling the watch head, the target holes at the three o'clock positions and the ear holes at the 6 and 12 positions are mainly drilled. When packaging, the target holes at the three o'clock positions need to be inserted with target tubes so that they can be connected to the movement in the dial later. The purpose of the ear holes is mainly to connect the head grain with the strap; During the drilling process, the target holes at the three time positions are different in size from the ear holes at both ends.
