Description

Watchband and wrist-watch

Technical Field

The utility model relates to a leather goods field especially relates to a leather watchband and wrist-watch.

Background

The watch band is a type of watch band commonly used in watches, and the structure of the watch band includes a short band assembly and a long band assembly. The cross-sectional structures of the long and short belts are as follows: the watchband surface leather, the middle core material layer and the watchband bottom leather are adhered into a whole by glue, wherein the watchband surface leather and the watchband bottom leather are usually made of animal leather, the middle core material layer is made of superfine fiber PU synthetic leather, and after the watchband is made, the outer watchband surface leather and the watchband bottom leather are easy to wrinkle when a user bends in the using process due to different shrinkage rates of the two materials, so that the visual effect is poor; the existing solution is to manufacture the watch strap surface leather and the watch strap bottom leather by selecting the part with the animal leather shrinkage rate close to the middle core material layer, but the manufacturing cost of the leather watch strap is greatly increased by the method. There is therefore a need for a strap that avoids the problem of the strap cover and strap base being prone to wrinkling when the strap is bent, and that does not add additional cost.
