Our suppliers aftermarket cases feature a similar octagon bezel, secured with visible screws, and integrated case design paying homage to the famous AP 'Royal-oak' style.

The aftermarket style butterfly clasp is another adding both elegance and functionality to the watch. Unlike traditional clasps, the butterfly clasp uses two hinged sides that open symmetrically, resembling a butterfly’s wings, which allows for a seamless, secure, and comfortable fit. This feature not only ensures a smooth, sleek look but also prevents the bracelet from being twisted or out of alignment when fastened.
