Abstract: A watch constituted by a case carried by a band, the case fastened on the band by a removable connection constituted by the interaction of two elements, a first element fastened on the band and a second element integral with the case. One of the elements is a hooking element while the other element is a locking element comprising a movable bolt biased by a resilient system, coupling it to the hooking element. The hooking element is constituted by a slider that interacts with a slide rail in the locking element, while the movable bolt comprises a locking projection engaged into a recessed profile on the slider. The movable bolt mounted in the locking element pivotingly around an axis is a class 1 lever including a first arm comprising the locking projection and a second arm biased by unlocking means.
