We aimed to overhaul the entire zipper design, to create something solid and high-quality like a watch strap. By devising a way to smoothen element engagement despite smaller inter-element gaps, we perfected a luxury zipper with a sense of flatness and seamlessness. This revolutionary design establishes the zipper as a luxurious embellishment, rather than just a fastening device. New technology is used to achieve high-quality operability to match the external beauty. The complex shape is created using new die-cutting and attachment methods. Flexibility is achieved by an optimal balance between esthetics and strength.
