Black PVD butterfly type folding clasp. Most watch strap sellers do not offer deployment buckles for sale. Antenen offers pin and folding buckles in different shapes and colors. The folding clasp opens in three parts: hence the name butterfly folding clasp. All pin buckles on a watch strap can be replaced by a folding clasp. Note: The bracelet should not be too thick. Maximum thickness: 2.5 mm at the tip of the longest part of the bracelet. The butterfly folding clasp prevents the premeditated wear of the leather. Once the buckle is attached to the 2 sides of the watch strap, the handling for the wear is carried out exclusively by the buckle.
