With the vision of making the watch industry and consumer culture more sustainable, Nordgreens Guardian was developed according to circular values. As part of this, an environmental analysis of a watch was conducted with scientists to innovatively optimise the watch design, resource use and supply chain for durability. The Guardian is therefore made of recycled steel from Outokumpu, the world leader in ISO14021 regulations. The Japanese movement works by automatic, and the bracelet and clasp follow durable design principles.
