A clasp for a wristlet has at least two movable blades (4), (5) articulated with respect to one another about an axis of the blades (51) and a locking device (10) making it possible to lock or unlock a first blade (5) relative to a second blade (4), respectively in closed and open configurations of the clasp. The locking device (10) is linked to the first blade (5) and has an actuation lever (2) intended for the actuation of the locking device by a user, a locking element (1) capable of cooperating with a complementary locking element (4a) of the second blade (4), and an intermediate element (3) linked to the locking element (1) by a first link device and to the actuation lever (2) by a second link device, at least one of these two link devices being provided with at least two degrees of freedom.

The application describes a watch band and methods of manufacture and use thereof. In various embodiments, the watch band includes a first portion and a second portion continuous with the first portion. The first portion can be made of a first material and be adapted to be located directly under a back of a watch case. The second portion can include a series of rigid links formed from a second material that is different than the first material. The second portion can be adapted to wrap around the wrist of a user. In various embodiments, the watch band can feature offset links to enable the watch band to curl around a user's wrist while maintaining the watch case at a low profile above the first portion. In some cases, the watch band can include a detachment mechanism remote from where the watch band attaches to the watch case.

A watch can include a first watch band portion and a second watch band portion both configured to be coupled with a mechanical watch. The watch can further include a circuit board associated with a controller, the circuit board and controller being removably retained by a clasp. The circuit board and the controller can be electronically and operatively independent from the mechanical watch.
