Lange watches are made from several hundred individual components, which are lovingly processed and then assembled by hand. When producing these individual components, we ensure that the raw materials used comply with international regulations. We believe our watches can last many years, as long as they are cared for. In a Lange watch, we only use components which we guarantee can be newly produced in the long term.
As a long-standing member of the Internationaler Reptilleder Verband (IRV – International Reptile Leather Association), we rigorously abide by the Washington Convention on International Trade in Endangered Species (CITES). The alligator leather used for our straps is sourced exclusively from farms in the USA where ethical animal husbandry principles are upheld. The leather trade is strictly state-monitored as well. The species protection seal on the alligator leather strap of a Lange watch includes a registration number that is checked by customs officials when imported, allowing each strap to be traced back to the source.
Responsible Jewellery Council
The Responsible Jewellery Council (RJC) is an international non-profit organisation which brings together representatives of the watch and jewellery industry from all over the world who undertake to observe strict requirements along their entire value chain. These regulations apply to not only social, ethical and environmentally friendly procedures, but also the guaranteed protection of human rights.
As an officially certified member of the Responsible Jewellery Council, we guarantee that all of our precious metals and jewels are responsibly sourced. Long-standing partnerships and meticulous evidence on all invoices from our suppliers guarantee that the raw materials (diamond, gold and platinum) used for our watches come from legitimate sources. In particular, we expressly rule out the use of diamonds from Myanmar and Marange in Zimbabwe – places which have been criticised for severe human rights violations. The quality of our diamonds is consistently tested and certified by an independent laboratory.
