As is known, watches are provided with a strap for wearing on the wrist; as a band of this wristwatch, for example, a band of tanned leather such as cow leather or crocodile leather is generally cut into a band shape, and the band-shaped leather is sewn with leather of different materials, thereby providing strength. In addition, a band of a wristwatch is also called a metal band, in which pieces made of metal or the like are connected in a chain shape, and the pieces are connected by a pin called an adjustment pin, so that the band is formed by bending the connected pieces along a wrist. In recent years, there is also a band-shaped watch band called a resin watch band, which is formed of a synthetic resin such as polyurethane. These watch bands are generally all composed of two band-shaped portions, and are made such that one end side of each band-shaped portion is connected to a body of the watch including a display portion, and the other end sides can be connected to each other by a metal clip or the like. However, for a wristwatch, the user desires that the wristband be length adjustable.
