Abstract: A wristwatch including a watch case, a bezel mounted to rotate on the watch case, and a dial including at least one luminous index. The luminous index is illuminated through the dial by at least one light source disposed underneath the dial and powered by an electrical energy source. An activation component for activating the light source is housed inside the rotating dial and cooperates with a detection element housed inside the watch case. The activation component, in a determined position of the rotating bezel, detects presence of the activation component by the detection element. The detection element then emits an electrical signal addressed to a microprocessor circuit housed inside the watch case. The microprocessor circuit emits in response to reception of the electrical signal emitted by the detection element an electrical signal that activates lighting of the light source for a determined period of time.

Abstract: A clasp for a bracelet having first and second free ends, the clasp including: a device for adjusting the useful length of the bracelet including an adjusting member carrying a first bracelet fastening member, and a lock having a default closed state, in which the adjusting member is fixed, and an open state, in which the adjusting member is free to slide with respect to a second bracelet fastening member to modify the useful length of the bracelet. The adjusting device is distinct from the locking member, and the lock is arranged to change from the closed state to the open state thereof by action of the user such that the adjusting member is shifted independently of the open or closed state of the clasp. The control member includes a push-piece displaceable in response to an action of the user, the push-piece being independent of the lock.
