Abstract
The invention provides a watch and a manufacturing method thereof. A watch upper sleeve comprises an upper sleeve base body. The side wall of the upper sleeve base body is covered by a gold foil layer. The upper sleeve and a watchcase are connected by adopting an interference fit mode. That is to say, in the assembling process of the watch, the gold foil is semi-packaged firstly, and then the gold covered upper sleeve is fixed on the watchcase via the interference fit mode so that a great grapping force is formed on the upper sleeve by the gold foil layer. Meanwhile, a welding seam is ingeniously concealed so that corrosive matter can be prevented from entering into the welding seam, and beauty of the gold covered upper sleeve watchcase is increased. A problem of corrosion of welding paste in the welding seam in the later use process due to existence of the welding seam in the manufacturing process of the existing gold covered watchcase is solved. A phenomenon of appearance of corrosive matter in the welding seam due to the fact that alloy elements of the welding paste in the welding seam chemically react with corrosive gas or liquid via contacting and galvanic reaction is generated by electron migration of different valences of metal elements in the long-term use process of the gold covered upper sleeve watchcase is eliminated.
