A battery-operated wristwatch includes a watch case, two strap parts and a clasp, wherein a battery housing including a battery is integrated in the clasp. One of the strap parts includes power transmission wires. The battery housing is coupled to the power transmission strap part by a first coupling that allows the transmission of a power signal. Likewise, the power transmission strap part is coupled to the watch case by a second coupling that allows the transmission of the power signal from the battery to the watch case. Particular embodiments are related to a watch provided with a deployable clasp comprising clasp portions which can be folded together, and wherein the battery housing is attached to one of the clasp portions.

The invention relates to a clasp for bands comprising a device for adjusting the length, wherein said adjustment device comprises a pivotally arranged member, and the said member can be activated by a user in order to activate the length adjustment. Preferably, the said pivoting element is part of the clasp cover. Preferably, the said pivoting element is articulated by means of axes that correspond to the shafts of the pushers of the clasp-locking mechanism.

The invention relates to a bracelet lengthening device, comprising at least one adjusting assembly (1, 2) that is movable relative to a clasp cover (21), the adjusting assembly (1, 2) and the cover (21) being provided with a first and a second fastening element (23, 35′), respectively, for fastening them respectively in several positions that are able to bring about different bracelet lengths, characterized in that the adjusting assembly (1, 2) and the cover (21) are also provided with a first and a second indexing element (15, 35), respectively.

A clasp for a watch bracelet including a cover connected on a first side to a first bracelet strand and on a second side to a second bracelet strand, a connection between the second bracelet strand and the cover of the clasp, the connection including a connecting link sliding in a longitudinal direction of the clasp between a first position and a second position. The clasp includes at least one first and one second bars mounted in the cover, and the connecting link includes a lever provided with a hook capable of moving from a first position wherein the hook is engaged with a first bar integral with the cover of the clasp, into a second position wherein the hook is released from the engagement thereof with the first bar and the link is free to slide so as to engage the second bar with a hook.

An approach is provided that automatically adjusts a band of a wearable electronic device. The approach detects conditions, such as activity-based conditions and location-based conditions, and automatically adjusts the band of the wearable electronic device based on the detected conditions.

A clasp is configured to permanently interlock around a flexible strip of material and includes first and second interlocking members. At least one interlocking member includes a Bluetooth communication device. Each interlocking member can include a plurality of hooks and a corresponding plurality of recesses, where the recesses of one interlocking member receive the hooks of the other interlocking member to secure a band within the clasp between the interlocking members. The recesses can be completely internal to the clasp to prevent external tampering. Each of the interlocking members can include various protrusions and ribs that compress and secure the band within the clasp, so as to prevent movement of the band between the interlocking members when interlocked.
