RIOS1931 watch straps are goods unobjectionable concerning hygiene and protection of species. We exclusively use coutchouc based glue, nickel-free fastenings made of stainless steel and hypo-allergenic padding leathers. In order to provide a higher level of protection we also apply a special coating to the surfaces, which were developed in collaboration with our tannery.

All leathers follow to regulations concerning formaldehyde and are free of harmful substances like PCP or AZO color, which may cause cancer.
Any and all RIOS watch straps made of reptile leathers bear the label of the IRV (International Reptile Association).
This guarantees that the leather in question is in compliance concerning protection of species and was purchased in accordance with the CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora).
