The device for fixing a wristband to a watch middle includes a connecting element (11) for connection to a wristband (10) or a watch middle (20), at least one pin (1) able to occupy two positions, one projecting from the connecting element (11) and another retracted into a housing (11a) of the connecting element (11), and a receiving element (21) for connection to a watch middle (20) or a wristband (10), having at least one bore (21a). The fixing device includes at least one insert (5), and is designed to occupy at least two configurations: a first configuration in which the at least one pin (1) occupies a position retracted into the connecting element (11), enabling a wristband to be separated from a watch middle, and a second configuration in which the at least one pin (1) occupies a position projecting from the connecting element and is positioned in the at least one bore (21a) of the receiving element (21), the at least one insert (5) forming an interface between the at least one pin (1) and the at least one bore (21a) and/or the housing (11a) to minimize frictional wear on rotation of the at least one pin (1) relative to the receiving element (21) and/or the connecting element (11) respectively.

It is herein disclosed a novel strap for a wearable electronic device and a wearable electronic device with such a strap. The strap features a first layer of microfiber and a second layer of natural or artificial leather as an outer layer. A layer of elastic adhesive attaches the first layer to the second layer.

An insert for a strand of a watch wristlet to manually lock and unlock the connection between the strand and a strip of a watch case, including a body and a latch, the body having a parallelepiped portion extended by a hook-shaped portion forming a housing for the strip, and the parallelepiped portion configured to be secured to the strand. The latch is hinged to the body to cause it to pivot around a hinge axis and includes a closing wall for closing the housing. The latch has locking means formed by a pin integral with the latch cooperating with a hole in the body and first return means to constrain the pin in the hole in a locking position. The latch has a length less than the length of the cavity so that when the latch is pushed manually in the direction of the hinge axis it releases the pin.

The invention discloses a smart watch, which comprises: a dial (10), a first and a second straps (20,24), connected respectively to both sides of the dial (10); wherein a first and a second displays (12,13) are disposed respectively on a front and a back of the shell body (11) of the dial (10), the first and second straps (20,24) are disposed with a plurality of clasps (21) and clasp holes (22) correspondingly, and the first and second displays (12,13) can have the same or different shapes and sizes, depending on whether the watch is worn on front or back, so that when worn on different side, different display is viewed to achieve complex application. Designing different appearances for the front and back of smart watch satisfies various esthetics, and manufacturing the first and second displays (12,13) monolithically simplifies the control circuit to improve smart watch quality.
