Wristwatch strap with protective layer that contacts the wrist

摘要

A wristwatch strap of leather or the like has a continuous non-porous barrier layer on the surfaces of the strap that contact the wrist of the wearer. The barrier layer consists of metal particles such as aluminum, noble metal or silver, having a particle size of 150 to 500 microns, preferably 200 to 350 microns, embedded in a matrix which consists of a synthetic resin. The barrier layer is effective to prevent the transfer of allergens and irritants from the material of the wristwatch strap, to the skin of the wearer.
