Sometimes referred to as a hidden clasp, the butterfly hasp serves as a concealed closure for men's and women's watches. Opening and closing a butterfly or hidden hasp isn't difficult and you won't forget once you learn. It only takes a few minutes to do and you don't need any materials or tools to assist you in this simple task.

Skill level:


  1. 1

    Grasp the band of the watch in both hands with your thumb and index finger of each hand, grasping either end of the butterfly hasp. Grab the opposite ends of the hasp where the watch stops being flexible and becomes stiff. The stiffness is the clasp.

  2. 2

    Make a bending motion with each end of the butterfly hasp in either hand. This pushes the centre of the hasp upward in a pitched shape. The seam of the clasp will begin to separate in the centre of the hasp.

  3. 3

    Unfold the hasp by pulling the opening seam of the clasp apart. This causes the hasp to open completely, which causes the band of the watch to widen in size by at least 1 inch.

Tips and warnings

  • To put on the watch, simply slide it over your wrist and then click the hinged ends of the opened hasp together.
