Sustainability matters

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.

Alligator leather

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 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.
免费在线视频 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. The quality of our diamonds is consistently tested and certified by an independent laboratory.

Careful use of resources

We have set ourselves the aim of continually reducing our energy consumption and optimising our energy footprint. This includes the careful use of natural resources such as paper, responsible waste management and the recycling of general and raw materials. We also favour working with regional service providers and pay attention to sensible, environmentally friendly logistics.
In 2015, A. Lange & Söhne opened a new manufacturing building. To make the manufactory as green as possible, a geothermal heat pump is used for heating, cooling and hot water. The use of the geothermal and green electricity to drive the heat pumps enables carbon-free energy supplies for the new building. The geothermal system that has been installed to this end is the largest in the Free State of Saxony to date.
