A wristwatch having a watch case that rests against the radial side of a wearer's wrist is provided. The wristwatch includes a radial watch having a rigid band with a first and second end that forms a gap. A watch case is secured between the ends forming a closed loop. The rigid band is monolithic and sized in such a way that the watch case is disposed on the radial side of the wrist when worn. The watch case includes a face that can be oriented towards the wearer for convenient viewing. In one embodiment, the band includes padding on an interior side.

A device for attaching a bracelet to a watch case, the device including, on the one hand, a bar secured to the watch case by a horn, and on the other hand, an insert integral with the end of a bracelet, wherein the bar and the insert are complementary in order to cooperate by interlocking to form removable assembly to make the bracelet interchangeable. The bar is formed by a cylindrical hollow body provided with two retractable pivots, and having at least one housing arranged to cooperate by interlocking with an insert, the bar including a device for holding the insert, and being arranged so as to pivot from a first position, in which the insert is capable of being positioned on the bar, into a second position in which the insert is locked onto the bar by locking device cooperating with the holding device.

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.

An attachment link for a watch band arranged to attach the band to a watch case between the horns, wherein a first end of the attachment link is fixed to a watch band strand and the second end of the attachment link is fixed to the case with a bar, wherein the link is between the horns and against the case. The attachment link includes a device for blocking pivoting in order to firmly hold the attachment link between the horns.

A band configured to couple a device to a body of a user is disclosed. The band includes a first link comprising a recess defined in a body of the first link, a leaf spring positioned in the recess and comprising a tongue portion protruding from the leaf spring, and a second link coupled to the first link and comprising first and second lip portions extending away from a body of the second link and separated from one another by a gap. The tongue portion is positioned in the gap between the first and second lip portions, and the first and second lip portions engage the leaf spring to retain the second link to the first link.

A device capable of being used for a long time is achieved. A power supply, a connection method of a power supply, or a connecting member, for easy attachment and detachment and non-detachment when in use, is provided. A power supply, a connection method of a power supply, or a connecting member for easy replacement is provided. A highly designed power supply is provided. Power from a battery is supplied to an electronic device through a connecting member including a pipe, a spring, and a pair of pivots. The pair of pivots are electrically insulated from each other, and electrically connected to any one of a pair of electrodes of the battery. The electronic device into which the pair of pivots are inserted includes a pair of bearings capable of receiving power.

A sleeve for use in an assembly for coupling a wristworn device to a first end of a strap. The sleeve has a first end dimensioned to be received in the recess in the inner face of the first lug of a wristworn device, an inner cavity dimensioned to receive therein the first end of a conventional spring bar, and a retractor coupled to the sleeve for urging the first end of the spring bar towards the second end of the spring bar. The second end of the spring bar is coupled to the second lug, the spring bar is coupled to the strap, the first end of the spring bar is positioned in the inner cavity of the sleeve and the first end of the sleeve is coupled to the first lug. A removable retractor for use with a spring bar, which allows for the use of a plurality of spring bars and therefore, lends itself to widespread use and retrofitting of an assembly that couples a strap to a wristworn device, is also provided.

A connector including an attachment member which has an attachment hole and is provided on one of a connection object and a connection target, and a connection member which includes a slide member that has a lever and is slidable in a cylindrical member inserted into the attachment hole, and is attached to an other one of the connection object and the connection target by the slide member protruding from an end of the cylindrical member, in which the attachment member has a slit hole which is formed extending from one end of the attachment hole to an other end of the attachment hole and in which the lever is slidable.

Disclosed are a connecting apparatus for a watch strap that enables a user to simply replace a watch strap without a separation tool, and a watch strap with the connecting apparatus. The connecting apparatus connects a body of a watch and a watch strap, and includes at least: a tube having a first hole; a first pin inserted in and being able to protrude from a first end of the tube; a second pin inserted in and being able to protrude from a second end of the tube; a spring disposed between the first and second pins, providing elasticity to the first and second pins, in first and second directions, respectively; a protrusive member connected to the first pin and protruding through the first hole; and a slider connected to the protrusive member, moving the first pin in the second direction, and having a portion overlapping the first hole.
