Abstract A watchband is formed of two contiguous strips, an outer nonmetallic strip, normally of a synthetic resin, and an inner metal strip. The metal strip is formed with an array of throughgoing perforations over substantially all of its surface and the nonmetallic strip is formed with a multiplicity of bosses each projecting through a respective perforation and extending beyond the inner face of the metal strip so that the band will rest via these bosses against the skin of the wearer.
