Abstract
The utility model provides a watch. A watch upper cover comprises an upper cover base. The sidewall of the upper cover base is covered with a gold foil layer. The upper cover and the watchcase are connected in the interference fit manner. In the watch assembly process, a gold foil is coated in a half manner, and then the gold-coated upper cover is fixed on the watchcase in the interference fit manner to make the gold foil layer form a good grasping force on the upper cover, and at the same time, the weld joint is hidden smartly to prevent the corrosive material from entering the weld joint, so the aesthetics of the gold-coated upper cover watchcase can be improved. According to the utility model, the problem of the corrosion of the soldering paste in the weld joint in the later utilization process with the existing gold-coated watchcase in the manufacturing process due to the existence of the weld joint can be solved. In the gold-coated upper cover watchcase long-time utilization process, alloying elements of the soldering paste in the weld joint will be in contact with corrosive gases or liquid to undergo chemical reaction, and metallic elements of different valences undergo the galvanic reaction due to electron transfer to make corrosive materials occur on the weld joint, and according to the utility model, the phenomenon can be eliminated.
