Abstract: A carbon fiber watch case includes a main body structure and a conductive structure. The main body structure has an inner surface and an outer surface. The conductive structure has a first contact on the inner surface and a second contact on the outer surface to electrically connect the inner surface and the outer surface of the carbon fiber watch case. The main body structure includes a braided body and a polymer body. The braided body includes a carbon fiber, and the braided body has a network-like structure. The polymer body at least fills a gap of the network-like structure of the braided body so that the braided body and the conductive structure form an integrated structure.

Abstract: In some embodiments, a braided watch band includes a braided band. The braided band includes a first braided band branch and a second braided band branch arranged in a thickness direction. The braided band further includes a first binding yarn and a second binding yarn. The first braided band branch and the second braided band branch to form a separate section and joint sections. In the joint sections, the first binding yarn and the second binding yarn form an orthogonally locking structure. In the separate section, the first binding yarn passes through one of the first braided band branch or the second braided band branch, and the second binding yarn passes through the other of the first braided band branch or the second braided band branch. Portions of the first braided band branch and the second braided band branch at the separate section form a loop.
