Abstract: An assembly for a consumer product, such as a wristwatch or other wearable electronic device, can securely retain a cover member against a housing of the product. A retaining member from within the housing can engage and secure the cover member to provide a fluid barrier. The cover member can include a window or other components of a sensor device. The parts can be easily disassembled without causing permanent damage.

Abstract: A set of watch straps include a first strap, the first strap including a first band, a first adapter, and a first lug connected in series, and a second strap, the second strap including a second band, a second adapter, and a second lug connected in series. The first lug is configured to slide into a first strap receiving groove of the watch, and the second lug is configured to slide into a second strap receiving groove of the watch. At least one of the first strap and the second strap is reversible.

Abstract: A system that transforms the APPLE WATCH®, or a similarly constructed wearable computing device, into a jewelry or wearable accessory that is adaptable to a wide variety of styles. The system includes two pins that are compatible with the device and provide multiple functionalities. The first pin has a bail that effectively turns the device into a pendant or any accessory that is desired, and the second pin has a hinge knuckle onto which other parts—for example a cover, a second bail, or a charm—can attach. When a cover is used, the first pin has the additional functionality of being an attachment point for closure. Both pins maximize unintentional interference with the device and support the device from opposing and/or pulling forces with minimal wear. The pins work in harmony to transform the device into any wearable jewelry the user desires.

Abstract: A biometric monitoring device and multiple carrying cases for same are provided. In some implementations, the case may be made from a flexible viscoelastic material and the biometric monitoring device may be slipped into a receptacle in the case through an opening in the case; the opening may become distended during the insertion of the biometric monitoring device. In some implementations, the case may feature a display window that, in combination with materials of the biometric monitoring device, may mask a display of the biometric monitoring device from view when the display is off and may allow the display to be seen when the display is displaying content.

Abstract: The present invention concerns a portable object (1). This portable object includes a case (2) to which a bracelet or strap (3) is fixed taking the form of two bracelet or strap strands.

Abstract: A strap-type watch band construction is fabricated from a blank. The blank includes three sections. A first section is folded over forming a double layer portion that is stitched and secures a buckle and a keeper and supports a watch casing, which is preferably slidably supported thereon. A second section is a single layer of the blank, extends from the first section, and includes apertures therethrough for receiving the buckle. A third section extends from the second section and is folded over to form a tip portion. The third section improves gripping and facilitates insertion of the tip portion through the buckle and the keeper. The single layer construction of the second section facilitates putting the watch band construction on the wrist as it is flexible and tends to form around the wrist.

Abstract: The invention concerns a device enabling reversibility and interchangeability of an object, such as a watch and a wrist watch, comprising at least one reversible and interchangeable element (110, 111) including a cavity (120, 121) and a removable projecting fixing element (203) integral with the bracelet or other support to be inserted axially parallel or not and to be moved in parallel with the element to the cavity (120, 121) up to a stop position and brought by rotation into its fixing position. The removable fixing element (203) can be made in different embodiments desired by a user. The device comprises a cavity in the middles (110, 111) wherein is housed the base (210) of a pivot (211) of the removable fixing element (203) which is integral with one end of the bracelet (204), whereby a rotational motion is imparted to a watch case (100, 104) and to its bracelet (204), independently of each other, so as to provide a watch with interchangeable double dial and a double-sided bracelet.

Abstract: A band that may be utilized for a timepiece, such as a watch, is disclosed. The band may have a plurality of joined links, and each link includes a cover member, an extension element, a first springbar, and a second springbar. The extension element defines a first channel and a second channel, the first springbar extends through the first channel to secure the extension element to the cover member, and the second springbar extends through the second channel to join the extension element to an adjacent cover member. In addition, the cover member is configured to join with an adjacent extension element that is separate from the extension element.

Abstract: A watch case with an interchangeable bracelet system includes a back with a neck to which a portion of a bracelet is removably coupled. A closure element closes the neck and pinches the bracelet against the back of the case. Preferably, the closure element is a ring that is attached to the back of the case by means of a bayonet device consisting of a lug that is inserted in a mating hollow. To prevent accidental separation of the closure element from the case, a compression joint may be placed in a seat provided in either the back of the case or in the closure element. The closure element compresses the joint and frictionally prevents accidental opening. The device enables the bracelet to be changed easily without tools.

Abstract: Strap 9 and case 1 assembly destined to be worn on the wrist with the strap 9 being fixed in a removable manner at its respective ends 10 linking up with connecting portions of the case 1. At least one of the connecting portions includes a hole 8 designed to receive a fastening part 16 of a decorative item 14, the corresponding end 10 of the strap 9 projecting into the hole 8 to lock the said decorative item 14 in place.

Abstract: A portable electronic device adapted to be worn on a user's wrist including an electronic unit including a transceiver for receiving and transmitting messages and a watch included within the electronic unit having movements for displaying a time of day.

At least one display is integrated with the electronic unit for the display of informative data.

Abstract: In the 6h-12h axis of the watchcase (1), two vertical bores (9) are made in the middle (2) of the watchcase. Inserted in these bores is one metal cylinder (10) each with a horizontal bore (12) and a vertical bore (14). Screwed into the horizontal bore (12), which has been provided with a threading (11), is a screw (23), which fastens the band connection (21) to the side (33) of the middle (2). Screwed into the vertical bore (14), which has been provided with an internal threading (13), is a screw (18) which fastens the back cover (3) of the watchcase to the middle (2). In the side (33) at 6h and 12h one horizontal or vertical ground area (22) each is foreseen in which the band connections (21) are somewhat recessed. Achieved through this configuration is that the band connections (21) for fastening the watchband have no play and do not turn.
