Watch case comprising an unfolding clasp for a flexible strap, with the unfolding clasp comprising: a middle connected to a first end of the strap, a base connected to the second end of the strap, an extension, connected in articulated fashion to the middle and to the base. The articulations between the middle and the extension and between the base and the extension are arranged in such a manner as to allow the middle, the extension and the base to superimpose in folded position, and to be juxtaposed in an unfolded position. The watch case further comprising a regulating cam for holding by compression and/or friction the strap against the base, the cam being capable of being swung to increase or reduce in a reversible manner the length of the strap in folded position.
