A watch system may include a watchband including a flexible member configured to be mounted onto a wrist of a user, and a puck including watch functionality. The watchband may have an end that has a concave curved shape. The puck may have a connection interface that has a convex curved shape. The connection interface may be to be removably coupled to the end of the watchband. The watchband and the puck may have corresponding locking features that are configured to rotationally and translationally fix the puck to the watchband. The corresponding locking features may be configured to be engaged when the watchband is translated relative to the puck and rotated relative to the puck by a predetermined rotation angle.

A band includes first and second pin member including first and second pin, an operation member that moves between first and second positions, a housing including a coupling part and an engaging part, and a guide part that guides and moves the first and second pin members between an engagement position and a release position. The first and second pin members move to the engagement position when the operation member is moved to the first position, whereas move to the release position when the operation member is moved to the second position. The engagement/release position is a position where each pin is located outside/outside the side surface of the housing in the width direction, and the engagement/release position is closer to the coupling/engaging part than the release/engagement position in the longitudinal direction.

An identification bracelet includes a wristband securable to a wearer. The wristband includes a plurality of openings for receiving a locking rivet and one or more openings for receiving one or more color-coded pins, a housing attached to the wristband, the housing having a pair of lugs with a slit, each lug extending from each side of the housing and adapted to receive the corresponding ends of the wristband inserted into the corresponding slits. The housing comprises a snap-on cover with at least a portion of the cover being transparent, a base, and a waterproof gasket insertable into the base. The snap-on cover is configured to be snapped on the base thereby creating a hermetically sealed waterproof structure. The housing also includes an information tag insertable into the housing and visible through the transparent portion of the housing.

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.

Systems may include a watch band, a watch body including at least one image sensor configured to capture a wide-angle image, a coupling mechanism configured to detachably couple the watch body to the watch band, and at least one biometric sensor on at least one of the watch band or the watch body. Various other related methods and systems.

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.

A sub-assembly of external parts including, a bolt interposed between a first component and a second component compressing together a joint, securing them together by axially blocking the first component, and which cooperates with the second component to enclose a ball occupying a well of depth greater than its diameter, that an orientation housing in the second component or the bolt includes, framed by channels of depth less than its diameter, limited by stops, which ball can occupy, when subjected to the gravity field and/or a magnetic field, both an orientation housing and a complementary housing of depth less than its diameter, that the bolt or respectively the second component includes, for their relative drive by the ball when it is simultaneously braced on a channel and a complementary housing.

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.
